The team used DNA analysis specifically the nifh gene that is characteristic of diazotrophs to measure the communities in the samples.
Often scientists study biodiversity at all levels--from genes to entire ecosystems. Currently researchers at the University of Missouri are employing genotyping to study movement patterns of African forest elephants in protected and unprotected regions of Gabon to better understand how human occupation of these areas might affect elephants on the African continent.
and fertility is affected partially by a deletion of a simple gene sequence. The presence and effects of this mutation have recently been discovered by scientists from Aarhus University University of Liã ge MTT Agrifood Research Finland in collaboration with the Danish Agricultural Advisory Service and the Nordic Cattle Genetic Evaluation.
We have discovered a deletion encompassing four genes as the causative variant and shown that the deletion is a recessive embryonically lethal mutation explains Goutam Sahana.
and pass the genes on to their calf for the calf to be affected. The bulls carrying the deletion can be identified routinely in on-going genomic selection program
The reason that the deleted gene sequence causing embryo mortality has become relatively widespread is that it has such as strong positive effect on milk yield.
This is at least the seventh example in livestock of an allele that is deleterious in the homozygous state being maintained at high frequency in the populations because of the selective advantage it confers to heterozygotes.
UC Davis scientists created the transgenic goats by transferring human genes for breast milk enzymes and proteins into goat embryos.
A group of Australian engineers had figured out how to silence the gene for PPO in potatoes.
They isolated four key genes involved in the production of natural sex pheromones of two moths:
Genes that code for pheromone biosynthesis were injected into the tobacco plant Nicotiana benthamiana via bacteria cultures (pictured.
By doing so, the team got the tobacco plants to express genes for moth pheromone production.
I had a chance to debate this topic a bit with Gene Bodenheimer, senior vice president of product lifecycle logistics for Genco ATC

and extraordinary genome structure enable the rapid evolution of genes. That ability helps the pathogen to outsmart its plant hosts.
The findings reveal the pathogen's unusual strategy to support the rapid evolution of critical genes, known as effector genes,
On the other hand, some effector genes can also trigger plants'immune responses--making them prime targets for combating P. infestans infection.

But a gene found in an ancient plant, a fern, might lead to solutions to sponge the toxin from contaminated areas.
They've isolated the gene (ACR3) that codes for a membrane protein within the ferns'vacuoles.
Potentially you could take these genes and put them in any organism that could suck the arsenic out of the Soil banks said.
Salt said rice plants could be modified with the gene to store arsenic in the roots of plants-instead of rice grains-in contaminated paddies.
and other ferns already have a single copy of the gene. Flowering species (from more recent branches of plant evolution) appear not to have ACR3 at all.
The animals have been modified genetically to switch off natural genes with instructions to create particular organs. Stem cells from other animals are introduced then to replace the missing instructions with organ growth from different pig species. For example
Some 95 percent of beets grown in the U s. carry the Monsanto bacterial gene that resists the herbicide glyphosate, present in Roundup Ready.
The crops contain a bacterial gene that allows them to withstand spraying with Roundup or its generic equivalents, known as glyphosate.
The environmental groups and others had said that the foreign gene might spread to organic or conventional nongenetically engineered crops,
It's just a marker to show that we can take a gene that was not originally present in the animal

I argue herein that aging can be slowed dramatically by fine-tuning your longevity genes. Indeed, scientific research carried out in the last 20 years has shown that lifespan can be modulated readily by a variety of genetic or dietary strategies.
Aging is linked to altered expression in more than a hundred genes; We employed artificial intelligence algorithms combined with animal longevity assays to screen for wide-spectrum herbal extracts that extend lifespan;
We succeeded in doubling animal lifespan using a novel class of nutrigenomic supplements that modulate genes involved in both aging and age-related disease.
but the impacts of this decline can differ with the individual genes and environment. The net result of aging in an animal population is a progressive increase in all-cause mortality and morbidity.
Thus, according to Medawar hypothesis, aging is caused indirectly by the declining forces of natural selection to select the best fitness genes for the aged animal as reproductive capacity declines.
wherein a gene may promote fitness in young fertile animals (and thus be selected for) but become a liability late in life leading to a subsequent decline in fitness.
Genescient has shown that several hundred genes have altered an expression in the Methuselah flies. In late 2010, Genescient sequenced the DNA of the wild type
and again found that more than a hundred genes appear to be altered in the long-lived Methuselah flies.
which predicts that aging leads to poorly functioning organisms as natural selection for optimal gene function wanes with age.
If there are hundreds of genes that function poorly as we age, then one possible anti-aging strategy is to utilize wide-spectrum nutraceuticals to modify gene expression to a state consistent with greater longevity.
as some of the youthful gene expression is inconsistent with longevity (e g. genes promoting rapid growth that can lead to cancer.
To affect as many longevity genes as possible I focused on complementary herbal extracts that have antioxidant, anti-inflammatory,
and metabolic potential (known factors in driving aging) along with a positive effect on longevity genes and a proven history of use in traditional herbal medicine to treat a wide spectrum of diseases.
