«We wanted to see if field - resistant pink bollworm from India harbored these same changes in the cadherin gene,» Fabrick said. (sciencedaily.com)
The caterpillar pest Helicoverpa zea (also known as cotton bollworm and corn earworm) has evolved resistance to four Bt proteins produced by biotech crops. (sciencedaily.com)
The researchers learned that the astonishing diversity of cadherin in pink bollworm from India is caused by alternative splicing, a novel mechanism of resistance that allows a single DNA sequence to code for many variants of a protein. (sciencedaily.com)
