The western red colobus has great bushy mutton-chops and a calico-patterned coat of bright rust white and black.
So why is sex nearly universal across animals plants and fungi? Shouldn't natural selection favor animals that forgo draining displays
Bdelloids have foreign DNA from bacteria and fungi in their chromosomes which is a great way to maintain genetic diversity.

Why do doctors refuse to believe there is a thing called microorganisms and parasites (germs worms fungus bacteria yeast insects etc.
Not only are they tolerant of pesticides/herbicides they also produce pesticides themselves through the use of fungus
The term soil is used usually to describe a more organic compound that's broken down plants and animals and fungi.
How about fungi do need mushrooms sunlight to grow? could we feed on them on a nuclear winter?
#Juniper Mold Threatens World Supplies Of Gina funguslike pathogen first discovered just five years ago now is wreaking havoc on juniper trees in the U k. This is the first time that this mold called Phytophthora
but only first discovered it in Argentina in 2007 The Phytophthora austrocedrae in South america are genetically different from those in the U k. so the U k. outbreak probably didn't come from The americas Forestry Commission scientist Sarah Green told ABC.
Other Phytophthora species are able to infect almost all of the fruit and nut trees people plant around the world.
The minerals in this solution (iron and other trace elements) have natural disinfectant properties that kill bacteria and fungi.
Not only will this kill the fungi and the bacteria in the soil it also conditions the soil by neutralizing the soil ph or soil acidity.
as a result of habitat loss not as a result of phytophthora austrocedrae as the article implies. Only one site in southern England has been identified for the pathogen with the majority of sites in the North of England and Scotland
Glucose Amylaseglucose Amylase is an industrial enzyme derived from a yeast or fungi. Glucose Amylase further catalyzes the breakdown of malto-oligosaccharides to glucose.

#Scientists Reveal The Cause Of The irish Potato Famineit's widely acknowledged that Phytophthora infestans a sort of funguslike pathogen also known as potato blight was responsible for the mid-19th-century potato famine that reduced Ireland's population through death and emigration by nearly 25 percent.
In the mid-19th century travel between the New and Old world increased bringing over new strains of Phytophthora infestans.
and found that there was still trace amounts of DNA from the Phytophthora infestans. Previously it was assumed that a strain known as US-1 was responsible for The irish Potato Famine
Tomorrow it could be altered genetically tree fungus. I wonder what exactly were they looking for in the meet to need DNA tests for...
Two fungi species that hail from the Eurasian steppes to which tumbleweed is native. He and his colleagues have submitted applications to release these exotic fungi on willing U s. farmers'lands.
Now they're just waiting for an answer. I'm very optimistic on its ability to control tumbleweed.
At the time plant pathologists in Hungary noticed a fungus infecting and killing local tumbleweeds.
Since then Berner and his colleagues has been studying that fungus Colletotrichum salsolae alongside another fungus called Uromyces salsolae.
what the fungi kill and don't kill. The latest studies included field tests of C. salsolae in Greece and Russia where C. salsolae already grows.
The fungi work against the tumbleweeds when they are saplings so they don't have the chance to grow into large bushes
if released the fungi wouldn't kill native plants. Those tests were performed in a biosafety level 3 greenhouse a precaution that was meant to protect not the human researchers who aren't susceptible to the diseases studied in the greenhouse but all of the plants outside of it.
Should the approval go through spreading the fungi will be cheap and easy. Scientists infect otherwise sterilized rice with the fungi then dump a half-kilogram pile of the rice every 5000 meters in the fields of those who want it.
Rain and tumbleweeds'tumbling will do the rest. It will eventually spread Berner says. Ultimately it's going to spread as far as tumbleweed spread u
Add Fungus The global population continues to grow and climate change is already tangibly reducing food harvests.
One answer to that question may be add fungus. Issie Lapowsky reports today for WIRED that a Seattle-based startup named Adaptive Symbiotic Technologies is almost ready to put a fungi-based product on the market that enables rice corn
and other crops to bear up amazingly well during drought and temperature extremes. According to Lapowsky the product called Bioensure is a blend of microscopic fungi that Dr. Rusty Rodriguez and his wife Dr. Regina Redman first discovered in the 1990s.
They had been trying to figure out how some plants were able to grow in the barren soil and peak 150 Degree-fahrenheit temperatures at the center of Yellowstone national park.
They discovered that fungi had colonized the plants and essentially lent them extra resilience. When the fungi were removed in the lab the plants failed under the same heat.
Since 2008 Redman has been tweaking fungi blends to work with wheat soybeans rice and corn crops.
Bioensure has been proven in real-world conditions Lapowsky writes: During the drought that destroyed much of the cropland in the Midwest in 2012 for instance Bioensure-treated corn crops generated 85 percent more yield than plants that were treated not.
Earlier he'd been photographing a brightly-colored fungus beetle for project called Meet Your Neighbors that's dedicated to reconnecting people with the wildlife on their own doorsteps
which may include the controlled introduction of biological predators like a fungus that's known to attack the beetle.
At fault was a fungus that continues its march around the planet. In recent years it has spread across Asia and Australia devastating plants there that bear the signature yellow supermarket fruit.
Scientists at the conference assumed that the fungus was limited to a single plot. The new report suggested the entire plantation was infested expanding 125 diseased acres to more than 3500.
I described a fungus commonly known as Panama Disease but scientifically termed Fusarium oxysporum f. sp. cubensis Tropical Race 4 (or Foc-TR4).
Researchers are now analyzing the strain of fungus found in Mozambique to see if it shares genetic markers with samples gathered elsewhere.
Whatever the origin it is certain that the new plantation was equipped poorly to handle the fungus.
DON'T KILL THE FUR FUNGI!!!New research you see has found that chemicals excreted by microbes in sloth fur had potent activity against a host of human pathogens
The study found that chemicals isolated from fungi in three-toed sloths were deadly for parasites that cause malaria and Chagas disease (Plasmodium falciparum and Trypanosoma cruzi respectively.
It also comes as no shock that fungi create chemicals of interest to drug developers as fungi have spawned drugs from penicillin to Lovastatin.
The researchers were surprised however by the scope of the fur-fungi's antimicrobial properities. Very few chemicals have been found to have activity against Chagas disease for example
Several of the chemicals isolated from the fungi also showed strong activity against human breast cancer cells. a
and vitamins B and C. Apart from fungi and insects the parasitic nematode Radopholus similis is considered a major banana pest.
and a little-known fungus is hurting Highbush cranberries. Both research articles were subject to the same peer review process
He sent pictures of the disease to an expert who identified the culprit as a rare kind of rust fungus about
The fungus was known to infect Highbush cranberry but nobody knew what effect it had on the plant.
the fungus may attack Highbush cranberry the most after wet spring weather. Wet springs are predicted to become more common in Daust's region of B c
This year there is tons of rust on the plants and there are hardly any berries Daust explained.
This is because many fungicides do not specifically combat fungi but prevent general processes in cells such as energy production
In addition to causing direct injury to the plant feeding can also provide the opportunity for infection by rot-inducing bacteria and fungi.
For iron rust goes right through Nordlander said. But for pure aluminum the oxide is so hard and impermeable that once you form a three-nanometer sheet of oxide the process stops.
The timber of many of the 198 species is of great economic interest because of its excellent insect and fungus resistance.
Nikki Rust of the University's Durrell Institute of Conservation and Ecology (DICE) said:''This research has shown for the first time that livestock guarding dogs can successfully be used in South africa to protect livestock from attack by predators as large as leopards or small as jackals.'
#How scavenging fungi became a plants best friendglomeromycota is an ancient lineage of fungi that has a symbiotic relationship with roots that goes back nearly 420 million years to the earliest plants.
More than two thirds of the world's plants depend on this soil-dwelling symbiotic fungus to survive including critical agricultural crops such as wheat cassava and rice.
The analysis of the Rhizophagus irregularis genome has revealed that this asexual fungus doesn't shuffle its genes the way researchers expected.
The fungus is a member of the Glomeromycota family and frequently colonizes many plants important to agriculture and forestry.
Glomeromycota also called arbuscular mycorrhizal fungi (AMF) play a vital role in how phosphorus and carbon cycles through the atmosphere and land-based ecosystems but exactly how it does this vital job is understood poorly.
It was a long hard road to a sequenced arbuscular mycorrhizal fungus. In 2006 shortly after the DOE JGI sequenced the first tree genome Populus trichocarpa it became apparent that it took a village (of other organisms) to raise a poplar tree.
Researchers Jerry Tuskan of Oak ridge National Laboratory and Francis Martin of INRA recommended that the assembly of Populus-associated fungi
Rhizophagus irregularis is the next in this linage to be released by the DOE JGI it follows the ectomycorrhizal fungal symbiont Laccaria the poplar rust pathogen Melampsora and dozens of bacterial genomes.
A relic of fungal evolution AMF diverged early on from other forms of fungus. They form dense clusters of branched structures--called arbuscules--in root cells much like a tight many-fingered handhold The arbuscules are the main route of nutrient exchange between plants and fungi.
Unable to live on their own AMF are entirely dependent on their plant hosts for the sugars they need for food.
Scientists theorize that the benefits these fungi provided enabled ancient plants to evolve during the Paleozoic era about 250 to 500 million years ago.
In exchange plants provided nutrients the fungi couldn't obtain themselves. Analysis of the R. irregularis genome also revealed several surprising details.
For comparison the button mushroom (Agaricus bisporus) also sequenced and published by the DOE JGI has a genome of about 30 Mb.
'Unlike many other fungi R. irregularis seems to lack mechanisms that can keep these transposable elements from running amok.
For example it can't make most of the toxins other plant-interacting fungi release probably the researchers speculate to avoid setting off the host plant's immune system.
It has also cast off most of its genes for breaking down plant cell walls a critical ability for free-living fungi that feed off dead organic matter in soils.
Teasing apart the complex relationship between soil fungi and plants is likely to have an impact on improving biofuel production from plant biomass.
#The ash dieback fungus, Chalara fraxinea, might have a mechanism to define territory and to combat virusesthe fungus
which causes Chalara dieback of ash trees has the potential to defend itself against virus attacks research by British scientists has shown.
Plant pathologists Dr Joan Webber from Forest Research the research agency of the Forestry Commission and Professor Clive Brasier found that the defence mechanisms which the Chalara fraxinea (C. fraxinea) fungus
Professor Brasier and Dr Webber studied C. fraxinea's genetic recognition system called a vegetative compatibility (vc) system in samples of the fungus from three different UK sites Their results
This has implications for studying the biology of the fungus and for controlling its spread.
Vegetative compatibility (vc) systems are a fungal equivalent of the tissue rejection systems in humans enabling the fungus to distinguish between self and non-self.
and survival of a fungus enabling it to define its territory to resist viral attack
Alternatively if the vc system is switched off'the germinating spores might cooperate during ash leaf infection leading to a greater spread of the fungus.
#Fungus kills ticksticks may be facing a dangerous fate. In the TICLESS project Bioforsk the Norwegian Institute for Agricultural and Environmental Research is hoping to determine
whether fungus can kill ticks in sheep pastures. This would also benefit future hikers. Tick##ites in sheep can lead to the disease tick-borne fever (TBF)
Bioforsk is therefore conducting field trials where the aim is to reduce tick populations in sheep grazing areas by using a tick pathogenic fungus called Metarhizium.
which is a formulation of an isolate of the tick pathogenic fungus Metarhizium. The fungus we are using in the trial is a natural enemy of insects
and mites found in soil. What we do is to increase the natural fungal population by releasing it in large quantities.
The death that awaits ticks exposed to this fungus is inhumane; fungal spores land and germinate on the skin (cuticle) of the tick
The fungus then grows and proliferates inside the tick. During this growth the fungus produces substances that are toxic and lethal to the tick.
The fungus continues to grow inside the tick until it fills the entire body. Thereafter it extrudes out of the tick again
and forms new spores on the outside of the body which can spread to new ticks Klingen explains.
You could for example apply the fungus along trails and on islands with a great tick population.
The trials that led to the quality assurance of the fungus and inclusion on EU's positive list conclude that the persistence in the wild was acceptable after application.
therefore looking at how effective the fungus is against ticks and also for how long it is present in the wild after having been applied as a biological control agent.
whether the fungus is effective and if it otherwise behaves acceptably here with us says Klingen.
#New antifungal composition effectively inhibits wide variety of fungiin order to overcome resistance to antifungal variety of pathogenic fungi
or chitosan oligosaccharides (COS) antifungal agents and additives that synergistically affect the growth of a variety of pathogenic fungi.
Because many fungal pathogens develop resistance to prolonged treatment with antifungal drugs it is desirable to find alternatives for their control in medical agricultural and those applications in which the fungi cause damage.
In clinics pathogenic fungi resistant to antifungal drugs are a major cause of mortality in patients.
This novel composition can be used as a medicine for clinical or veterinary use for the treatment and/or prevention of fungal infections by pathogenic yeasts and filamentous fungi such as Candida spp.
In agriculture pesticide treatments preferably in the control of diseases caused by pathogenic fungi as Botrytis cinerea and Fusarium oxysporum.
The research group has led numerous laboratory tests that have successfully proven the effectiveness of this novel composition of fungal growth inhibition of numerous species of pathogenic yeasts and filamentous fungi.
Together with a number of partners scientists from Wageningen UR (University & Research centre) have demonstrated that the disease--caused by the fungus Fusarium oxysporum f. sp. cubense--has migrated now also to Jordan.
Late last century however a new highly aggressive strain of the fungus was discovered in Southeast asia.
The Jordanian Ministry of Agriculture later sent samples of the fungus to Professor Randy Ploetz of the University of Florida who forwarded them to Gert Kema a scientist at Wageningen UR.
Phd students from Gert Kema's research group infected different banana plants with the fungus from the Jordan samples.
#Tapping fungus to unlock energy: Crafting a better enzyme cocktail to turn plants into fuel fasterscientists looking to create a potent blend of enzymes to transform materials like corn stalks
Many of today's efforts revolve around the fungus Trichoderma reesei which introduced itself to U s. troops during WORLD WAR II by chewing through their tents in the Pacific theater.
The fungus actually makes dozens of cutting enzymes each of which attacks the wrapping differently. Chemists like Wright are trying to combine
Wright's study focused on a subset of the fungus's collection of cutting tools on enzymes known as glycoside hydrolases.

Here Pseudomonas produce antibiotics that plants use to defend themselves against fungi trigger the rooting process
This insects alongside some fungi bacteria and viruses cause annual loses of between four and ten percent of all the stored grains worldwide mainly corn wheat sorghum rice and beans.
Gillespie explained that fungi is great at breaking down lignin in plants and bacteria can help break down the rest
so we are hoping to find out more about the role of fungi in the decomposition of organic matter in soil.
It explains that both types of cancer can be originated by the ingestion of food contaminated with aflatoxins produced by the fungi Aspergilus flavus and A. parasiticus.
and airborne the fungi that produce them are an olive green mold that can be found in refrigerators besides they are very resistant to high temperatures.
In the lone exception a soil fungus that was typically beneficial to plants began growing so rapidly that it impeded plant growth.
Unlike the fungi that use this communication method in soil the E coli could be grown in clear agar gels in a petri dish
In wood fallen to the forest floor it controls the rate that fungi advance through the wood cells to cause decay
He is also a leading authority on the biochemistry of brown rot wood-decay fungi
His study of the brown rot fungi led him to study tree defenses at the nanostructure scale.
Such perspectives could include a more diverse array of toxins for the control of pest populations possibly supplemented with a biological component such as pathogenic fungi or parasitic wasps.
and fungi to evolve into diverse multicellular life forms. Jeffrey Silberman a professor of biological sciences isolated a new unicellular anaerobic eukaryote
Animals plants and fungi are all eukaryotes; that is they have complex cells with organelles such as a nucleus and mitochondria.
but unequivocal relative to a supergroup of eukaryotes that include fungi and animals. It provides a glimpse of the various components of cell-to-cell adhesion
Leafcutter ants for example carry bacteria that help prevent other fungi from contaminating their fungal gardens.
and Advanced Studies (Cinvestav) who use different strains of fungi and bacteria to promote development
The fungi that provide benefits says Olalde Portugal are called the myccorrhizal. When in contact with the roots a biochemical communication starts that allows the trees to adapt with no problems
. In addition the specialist stresses that the plant with myccorrhizal fungi perform photosynthesis in a more efficient way using less water than those who don't have the association.
However not all bacteria or fungi perform with the same efficiency. For this reason a very important part of the research consisted in selecting the best strains specific for oaks pines mesquites acacias and fruit trees.
They season the wood for barrels and dry it outside or indoors a step that exposes it to fungi and bacteria.
Diseases such as fungi and viruses can attack wheat and lower yields. This research quantifies the impact of weather diseases and new wheat varieties on yields.
Estimates of the amount of missing data were based on 7539 peer-reviewed studies about animals fungi seed plants bacteria and various microscopic organisms.
Crop pests include fungi bacteria viruses insects nematodes viroids and oomycetes. The diversity of crop pests continues to expand
Losses of major crops to fungi and fungi-like microorganisms amount to enough to feed nearly nine percent of today's global population.
In addition the rice blast fungus which is present in over 80 countries and has a dramatic effect both on the agricultural economy
and leaves into better biofuela fungus and E coli bacteria have joined forces to turn tough waste plant material into isobutanol a biofuel that matches gasoline's properties better than ethanol.
The fungus Trichoderma reesei is already very good at breaking down tough plant material into sugars.
and a recent doctoral graduate in Lin's lab. The fungi turned the roughage into sugars that fed both microbe species with enough left over to produce isobutanol.
The harmonious coexistence of the fungi and bacteria with stable populations was a key success of the experiment.
Lin's team used game theory to analyze the relationship between the fungi and bacteria. Breaking cellulose down into sugar is hard work
Meanwhile the E coli use the sugars without offering the fungus anything in return which makes it a cheater.
because the fungi produce the sugars near their cell membranes which gives them the first crack at using the sugars.
#Traditional forest management reduces fungal diversityin the beech groves of Navarre a team from the UPV/EHU-University of the Basque Country has analysed the influence exerted by forestry management on the fungi populations that decompose wood.
This wood if available ought to be decomposing as it is the habitat of many living beings like lignicolous fungi.
These fungi are capable of decomposing dead wood and turning it into organic and inorganic matter.
So clearing away the dead wood from the forests is ecologically harmful for the fungi.
Nerea Abrego-Antia and Isabel Salcedo-Larralde biologists in the Department of Plant Biology and Ecology of the UPV/EHU-University of the Basque Country have quantified recently this effect on fungi populations that live off dead
and classical forest management are harming the community of saproxylic fungi. What is more the researchers have discovered that in the forests being exploited various fungi species are disappearing
and in some cases even whole families are affected. The conclusion of the research is crystal clear:
the clearing away of remains of dead wood is harming the populations of lignicolous or saproxylic fungi.
Yet many fungi have to be identified under the microscope although there are known species that are very large like the tinder fungus Fomes fomentarius.
But it is more difficult to gather samples of the rest and identify them and it takes longer.
After classifying the debris the fungal species existing in each were identified in other words the community of fungi existing in each twig.
However according to the research by Salcedo and Abrego the factor that exerts the most influence on the diversity of saproxylic fungi is the diversity of the woody debris not the volume of wood in other words that the nine groups classified should appear the maximum possible number of times.
At the same time the influence exerted by forest fragmentation on the presence of fungi is also being analysed.
and classical forest management are harming the community of saproxylic fungi at least in the zones studied.
the closest known non-disease causing relatives of the fungus that causes WNS. These fungi many of them still without formal Latin names live in bat hibernation sites
and even directly on bats but they do not cause the devastating disease that has killed millions of bats in the eastern United states. Researchers hope to use these fungi to understand why one fungus can be deadly to bats
while its close relatives are benign. The study by Andrew Minnis and Daniel Lindner both with the U s. Forest Service's Northern Research Station in Madison Wis. outlines research on the evolution of species related to the fungus
causing WNS. The study is available online from the journal Fungal Biology. Identification of the closest known relatives of this fungus makes it possible to move forward with genetic work to examine the molecular toolbox this fungus uses to kill bats according to Lindner a research plant pathologist.
Ultimately we hope to use this information to be able to interrupt the ability of this fungus to cause disease.
The study is an important step toward treating WNS according to Mylea Bayless Bat Conservation International's director of conservation programs in the U s. and Canada.
This research increases our confidence that this disease-causing fungus is in fact an invasive species Bayless said Its presence among bats in Europe where it does not cause mass mortality could suggest hope for bats suffering from this devastating wildlife disease.
which the fungus belongs resulting in a new name: Pseudogymnoascus destructans or P. destructans. This research represents more than just a name change according to Bayless.
Understanding the evolutionary relationships between this fungus and its cousins in Europe and North america should help us narrow our search for solutions to WNS.
For this study in particular USGS and Fish & Wildlife Service partners played critical roles collecting the fungi used in these studies.
