drought tolerance in cowpeascowpeas known as black-eyed peas in the U s. are an important and versatile food legume grown in more than 80 countries.
New and improved varieties of cowpeas have numerous adaptive traits of agronomic importance such as 60-70 day maturity drought tolerance heat tolerance aphid resistance
Dr. B b. Singh a visiting scholar and cowpea breeder with the Texas A&m soil and crop sciences department;
or SNP markers the latest DNA marker technology enabling efficient manipulation of heat and drought tolerances in cowpeas and related species Zhang said.
Cowpeas were chosen for the study because they are a high protein grain vegetable fodder and high nitrogen-fixing legume that can be intercropped with corn cotton
and other crops in many countries including the U s. Zhang said. We know it is highly tolerant to drought heat
and drought tolerances in cowpea and related species. Zhang said they have developed already a mapping population of 110 recombinant inbred lines from a cross of two cowpea lines that are highly tolerant or susceptible to both drought and high temperature.
To collect sheath saliva the scientists placed organic grape tomatoes in the cages. After two days of stink bug feeding they removed the tomatoes from the cages
and used forceps to extract the hardened sheaths from the surfaces of the tomatoes. They then processed
and analyzed the sheaths for protein content. We found that the watery saliva and the sheath saliva have distinct protein profiles Felton said.
In addition they found a large number of proteins from tomato. These results reveal that the protein composition of the sheath is a mixture of insect
We used extraordinary precaution to avoid disrupting tomato tissues during the collection of the sheaths
so we do not believe that the composition of tomato proteins in the sheath material is a spurious artifact of our collection methods

#Genetically modified spuds beat blightin a three-year GM research trial scientists boosted resistance of potatoes to late blight their most important disease without deploying fungicides.
In 2012 the third year of the trial the potatoes experienced ideal conditions for late blight.
The trial was conducted with Desiree potatoes to address the challenge of building resistance to blight in potato varieties with popular consumer and processing characteristics.
The introduced gene from a South american wild relative of potato triggers the plant's natural defense mechanisms by enabling it to recognize the pathogen.
Cultivated potatoes possess around 750 resistance genes but in most varieties late blight is able to elude them.
With new insights into both the pathogen and its potato host we can use GM technology to tip the evolutionary balance in favor of potatoes and against late blight.
In Northern europe farmers typically spray a potato crop 10-15 times or up to 25 times in a bad year.

#Conserving potato agrobiodiversity: Top-down and bottom-up approach neededmashed smashed and fried Americans love potatoes but only a few varieties are grown in much of North american agriculture.
In South america where potatoes originated more than 5000 varieties continue to exist. A Penn State geographer is gathering all the information he can about the agrobiodiversity of these uniquely adapted tubers with an eye toward sustainability of this fourth largest food crop worldwide.
In the U s. we rely primarily on 10 to 12 types of potatoes total said Karl Zimmerer department head and professor of geography.
In fact mostly we use only 5 to 8 varieties. In South america by contrast there are 74 different types of potatoes in a single field.
The fields tubers and landscapes are visually stunning. Zimmerer has studied high-agrobiodiversity land use for over 20 years
He first looked at diversity within individual potato fields and then scaled up to individual communities and landscapes.
People in a community have expert knowledge of 150 to 180 varieties of potato he said.
People in Peru for example love to eat potatoes and think that theirs are vastly superior to
They want to hang on to their high-agrobiodiversity potatoes and we want them to hang due to nutritional ecological and other conservation advantages.
Scaling up even more Zimmerer looked at potato fields on the landscape level--typically groups of 5 to 15 communities
Because the major potato growing area encompasses large parts of northern South america Zimmerer needed a novel approach
There are 4000 to 5000 different varieties of potato in Chile Colombia Northern Argentina Peru Bolivia Ecuador
and analyzing region-scale areas of concentrated agrobiodiversity are important as are the global institutions such as the International Potato Center in Peru.
But perhaps the most important part of the top down study is held the knowledge by expert potato taxonomists who have long histories of geographically extensive work.
He is a Peruvian who has worked from Chile to Venezuela and has an extraordinary knowledge of major areas where diverse potato types are located.
While many experts are local to potato growing areas other experts come from Europe and North america.
To assemble an expert database of information about locations of potato hotspots Zimmerer uses a two-pronged approach.
For those comfortable with computers he asks them to delineate on Google earth maps the regions of concentrated agrobiodiversity.
and keep track of the potatoes growing in their and their neighbor's fields. Zimmerer's approach may eventually be used for visualizations that help enable the local crowdsourcing of this agrobiodiversity.
The local farmers generally identify their potatoes on their culinary properties and uses--floury soup making or freeze drying said Zimmerer.
Interestingly the culinary uses correspond to the elevations where the potatoes grow--soup potatoes have the lowest elevation floury potatoes in mid elevation
and freezing potatoes are the highest. This type of information from the knowledge systems of farmers--often women--coupled with top down image analysis visualization
and new strategies for sustainable use of the extraordinarily high levels of biodiversity within the Andean potatoes.

#Better broccoli, enhanced anticancer benefits with longer shelf lifewhile researching methods to increase the already well-recognized anticancer properties of broccoli researchers at the University of Illinois also found a way to prolong the vegetable's shelf life.
And according to the recently published study the method is a natural and inexpensive way to produce broccoli that has even more health benefits
Jack Juvik a U of I crop sciences researcher explained that the combined application of two compounds both are extracted natural products from plants increased the presence of cancer-fighting agents in broccoli
We had figured out ways to increase the anticancer activity in broccoli but the way we figured it out created a situation that would cause the product to deteriorate more rapidly after application Juvik said.
For fresh-market broccoli that you harvest it's not too big a deal but many of these products have to be shipped frozen cut up
The researchers first used methyl jasmonate (Meja) a nontoxic plant-signal compound produced naturally in plants) to increase the broccoli's anticancer potential
which they sprayed on the broccoli about four days before harvest. When applied Meja initiates a process of gene activity affiliated with the biosynthesis of glucosinolates (GS)
which are compounds found in the tissue of broccoli and other brassica vegetables (such as cauliflower cabbage and kale).
They applied the compound after harvesting the same broccoli that had already been treated with Meja before harvest.

The regional agricultural authorities furthermore seemed unaware that bees visited flowering soybeans to collect nectar and pollen.
As far as we could determine every kind of GMO soybean grown in Campeche is approved for human consumption said Roubik.

#Nitrogen management studied in greenhouse pepper productionas consumer demand for year-round fresh produce increases vegetable
