The widespread use of antibiotics in livestock for preventive or curative purposes or as growth promoters directly contributes to the increasing prevalence of resistant strains of bacteria to antibiotics both at local and global levels.
since the completion of the first high-quality rice genome sequence in 2005 there has been limited change in breeding practices that are important for producing improved and better adapted rice strains.
which take advantage of the natural variation between different plant strains and information on the genetic mechanisms that underlie these traits to select strains for breeding that will be more successful in producing hybrid strains with characteristics that are suited highly for growing successfully in different environments.
Dr. Zhikang Li the Project Director at CAAS stated that the 3000 Rice Genomes Project is part of an ongoing effort to provide resources specifically for poverty-stricken farmers in Africa
not only 13.4 terabytes of data they have collected also seeds from each strain (available in the International Rice Genebank Collection housed at IRRI).
Having banked seeds is essential to make full use of these now genetically defined strains to develop
and sustain the most appropriate hybrid strains for different environments. There remains however one additional component to achieve this goal:
and breeders to directly link the genetic information (genotype) to the physical traits (phenotype) of these different strains.
since the development of agriculture typically use apparent physical traits to guide strain selection for crossbreeding with the hope that the offspring will manifest a combination and improvement of the desired traits such as drought pest and disease resistance
when two strains are bred. Thus trial and error and multiple successive breeding stages are required often. Having full knowledge of the genetic makeup of a plant allows researchers to identify genetic markers related to specific physical traits
This information allows a breeder to make more intelligent choices in strain selection resulting in more accurate and rapid development of rice strains that are suited better to different agricultural environments in poor and environmentally stressed economies.
As traditional methods of controlling crop disease become less effective the need to breed new strains of crops with an inbuilt resistance to the disease pathogens increases.
which will help us to be more successful in breeding new strains of crops for resistance.
help dairy producersconsumers may have more palatable low-fat products and milk producers a solution to an industry-wide problem through use of a unique strain of lactic acid bacteria according to Ashraf Hassan
After examining bacteria from the dairy environment for more than 15 years Hassan found a strain that mimics fat.
The strain Hassan discovered produces polysaccharides with high water binding capacity that then improve the quality of low-fat dairy products.
The polysaccharide produced by this strain also improves the functionality of proteins recovered from the cheese by product whey Hassan explained.
Furthermore the polysaccharide produced by this strain minimizes the negative impact of heat on milk protein during pasteurization according to Hassan.

The current study describes how crossbreeding the fat-1 mouse with another strain transgenic for the c. elegans gene fat-2
Called the Omega mouse this strain produces both omega-6 and omega-3 fatty acids in its tissue.
The crossbreeding protocol produces four different strains within the same litter--Omega mice that express both fat-1 and fat-2 strains that express only one of the c. elegans genes
Even when fed a high-carbohydrate fat-free diet both the Omega and fat-2 strains produced significant levels of both essential fatty acids.

After screening many hundreds of potential biocontrol strains of bacteria that were isolated from farms and natural environments in the Mid-atlantic region we found about 10 isolates of bacteria representing very different genera
The resistant strains multiply in the fly and can be left behind on food by fly regurgitation or spitting and defecation.
The resistant strains then survive and are selected by antibiotic treatments. Currently we have situations where people get infections they die from
We just know there are multiple venues where wildlife can acquire resistant strains and move them around in the environment.

According to the National institutes of health cirrhosis is the 12th leading cause of death by disease in the U s as with many other human pathologic conditions end-stage liver disease goes hand in hand with oxidative stress
Cells keep oxidative stress under control through various mechanisms said Donna Zhang a professor in the UA Department of Pharmacology
Under normal healthy conditions when no oxidative stress response is needed an enzyme called Keap1 constantly chews up Nrf2 keeping its level low.
Then under stress from reactive oxygen molecules or when you eat antioxidants from certain plants like broccoli sprouts it prevents Keap1 from eating up Nrf2 allowing it to accumulate in the cell explained Zhang who is also a member of the UA BIO5 Institute.
when subjected to high oxidative stress to limit the damage from the destructive oxygen compounds. During liver cirrhosis Nrf2 should be induced by oxidative stress
but for reasons unclear until this study this does not happen. This was a puzzle before we did our study she said.
When Zhang and her colleagues studied tissue samples from a human cirrhotic liver they discovered the reason behind the inexplicably low Nrf2 levels in the face of rampant oxidative stress.
As liver cirrhosis progresses excessive inflammation triggers the garbage-mediated stress response and Hrd1 becomes very abundant

Climate change is expected also to intensify several stresses that forests already face such as damaging insect pests and diseases drought and wildfire.
Higher levels of green space were associated with lower symptoms of anxiety depression and stress. The study published recently in the International Journal of Environmental Research
and Public health combines mental-health data from the Survey of the Health of Wisconsin (SHOW) and Landsat 5 satellite data from July 2009 that analyzed how much vegetation was present in each of the SHOW census blocks.
About 2500 Wisconsin residents from 229 neighborhoods answered an assessment that asked them to rate their symptoms of depression anxiety and stress.
They found that across all strata of society people who lived in a neighborhood with less than 10 percent tree canopy were much more likely to report symptoms of depression stress and anxiety.
It also suggests a relatively simple solution to improving the mental health of poor urban neighborhoods:
The greening of neighborhoods could be a simple solution to reducing stress says Malecki. If you want to feel better go outside.
In addition to the stresses of a warming climate they may face competition and displacement from more cosmopolitan birds like blue jays which tend to come along with residential development.
Put under stress through physical exertion--such as long-distance walking or running--they gain in strength as the fibres are added

of stress: biotic generally caused by infectious organisms like bacteria; and abiotic caused by environmental agents like nutrient deficiency flood and salinity.
Traditionally scientists have believed that different sets of genes regulated plants'responses to biotic and abiotic stress.
However Wusirika and Shaik discovered that 1377 of the approximately 3800 genes involved in rice's stress response played a role in both types stress.
About 70 percent of those master genes are co-expressive--they turn on under both kinds of stress.
Typically the others turn on for biotic stress and turn off for abiotic stress. The scientists looked at the genes'response to five abiotic stresses--drought heavy metal contamination salt cold and nutrient deprivation--and five biotic stresses--bacteria fungus insect predation weed
competition and nematodes. A total of 196 genes showed a wide range of expressions to these stresses.
The top genes are likely candidates for developing a rice variety with broad stress-range tolerance Wusirika said.
Next they would like to test their findings. We want to do experimental analysis to see if five or 10 of the genes work as predicted he said.
Their study is described in the paper Machine learning Approaches Distinguish Multiple Stress Conditions using Stress-Resposive Genes
and Identify Candidate Genes for Broad Resistance in Rice published in the January edition of Plant Physiology.
Professor Hidetoshi Saze of the OIST Plant Epigenetics Unit is leading a new research project to develop a new strain of rice that produces digestion-resistant starch to prevent these diseases.
This new strain of rice is expected to serve as an alternative preventative measure. In addition to its anti-obesity effect gathering evidence suggests that the rice with digestion-resistant starch may also provide other benefits such as lower blood sugar levels reduced neutral fat and harmful cholesterol levels and prevention
Despite its great promise when researchers planted the original strain of resistant-starch rice in Okinawa the yield per hectare was about half that achieved in mainland Japan.
Saze and his team then started hybridizing the resistant-starch rice with local strains to genetically design a new strain of rice suited to Okinawa's climate.
Saze is analyzing genomes of these rice strains. He is also using plant incubators in his unit to shorten the vegetation period of the new rice.

#Birds of all feathers and global flu diversitya group of international scientists have completed the first global inventory of flu strains in birds by reviewing more than 50 published studies
and performed as part of the USAID PREDICT project identified over 116 avian flu strains in wild birds.
This surprised virologists as the strain had caused never before disease in humans. To date there have been more than 300 clinical cases of H7n9 with a 33 percent mortality rate.
This year another strain known to infect birds H10n8 has caused human cases for the first time. As was the case in the H7n9 outbreak most direct bird-to-human spillover events
Completing the first global inventory of flu strains in birds is a key step in building that understanding.
Mallards carry the highest number of strains at 89 and ruddy turnstones were second with 45.
The more a strain was shared across wild bird types the more likely it was to be found in domestic birds a risk factor for spillover events.
They also noted that some strains could be specific to certain bird types. For example gulls and shorebirds (Charadriiformes) carried ten strains that have not been identified in any other bird order.
According to Dr. Olson This inventory isn't about blaming wild birds but it allows us to map
