which was designed to make an insect-killing bacterial protein called Bt toxin. The results could have major impacts for managing pest resistance to Bt crops.
Bt crops have had major benefits for society said Jeffrey Fabrick the lead author of the study and a research entomologist at the USDA Agricultural research service in Maricopa Arizona.
By understanding how insects adapt to Bt crops we can devise better strategies to delay the evolution of resistance
and extend these benefits. Many mechanisms of resistance to Bt proteins have been proposed and studied in the lab
but this is the first analysis of the molecular genetic basis of severe pest resistance to a Bt crop in the field said Bruce Tabashnik one of the paper's authors and the head of the Department of Entomology in the UA College
of Agriculture and Life sciences. He also is a member of the UA's BIO5 Institute.
Based on laboratory experiments aimed at determining the molecular mechanisms involved scientists knew that pink bollworm can evolve resistance against the Bt toxin
and implement resistance management strategies such as providing refuges of standard cotton plants that do not produce Bt proteins and releasing sterile pink bollworm moths.
Planting refuges near Bt crops allows susceptible insects to survive and reproduce and thus reduces the chances that two resistant insects will mate with each other
As a result pink bollworm has been eradicated all but in the southwestern U s. Suppression of this pest with Bt cotton is the cornerstone of an integrated pest management program that has allowed Arizona cotton growers to reduce broad spectrum insecticide use by 80
In the U s. pink bollworm populations have not evolved resistance to Bt toxins in the wild. However resistant pink bollworm populations have emerged in India
which grows the most Bt cotton of any country in the world. Crops genetically engineered to produce proteins from the bacterium Bacillus thuringiensis
--or Bt--were introduced in 1996 and planted on more than 180 million acres worldwide during 2013.
Organic growers have used Bt proteins in sprays for decades because they kill certain pests but are not toxic to people and most other organisms.
Pest control with Bt proteins--either in sprays or genetically engineered crops--reduces reliance on chemical insecticides.
Although Bt proteins provide environmental and economic benefits these benefits are cut short when pests evolve resistance.
The emergence of resistant pink bollworm in India provided the researchers an opportunity to test the hypothesis that insects in the field would evolve resistance to Bt toxin by the same genetic mechanism found previously in the lab. In the lab strains the scientists had identified mutations in a gene
Binding of Bt toxin to cadherin is an essential step in the intoxication process. Mutations that disrupt cadherin block this binding
which leaves the insect unscathed by the Bt toxin. We wanted to see if field-resistant pink bollworm from India harbored these same changes in the cadherin gene Fabrick said.
Our findings represent the first example of alternative splicing associated with Bt resistance that evolved in the field said Fabrick who is also an adjunct scientist in the Department of Entomology at UA.
Mario Soberã n a Bt expert at the Universidad Nacional Autã noma de MÃ xico in Cuernavaca who was not an author of the study commented This is a neat example of the diverse mechanisms insect
An important implication is that DNA screening would not be efficient for monitoring resistance of pink bollworm to Bt toxins.

#Hydrologists find Mississippi river networks buffering system for nitrates is overwhelmeda new method of measuring the interaction of surface water
and groundwater along the length of the Mississippi river network adds fresh evidence that the network's natural ability to chemically filter out nitrates is being overwhelmed.
in the Mississippi river network goes through a natural filtering process as it flows to the Gulf of mexico.
The analysis found that 99.6 percent of the water in the network passes through filtering sediment along the banks of creeks streams and rivers.
While further research is needed this would make it unlikely that natural systems can accommodate the high levels of nitrates that have made their way from farmland and other sources into the river network's waterways.

and placed them at each site so they could watch how quickly they dissolved. To determine whether local growing conditions were poor for the grasses they planted healthy grass in each site
and then protected it from all herbivores including the crabs. To assess whether any site had too much nitrogen they took leaves of the grasses at each site back to the lab ground them up
and analyzed their chemistry. In the second week in July they measured herbivory at each site by walking a 20-meter line at each site
and then stopping every two meters to measure signs of crab damage on 100 cordgrass stalks.
They even measured how hard the marsh soil was at each site. When fall came they analyzed all the data.
The number crunching revealed that differences in herbivory at each site explained 73 percent of the variation in die off from at each site.
