Resistant wheat rebuilds cell walls when attacked by Hessian flies
Date:5/19/2010

thought to be responsible for cutin and wax production was affected by the fly larvae.

Nemacheck said real-time polymerase chain reactions were used to quantify gene expression. The process uses an enzyme and other reagents to amplify target sequences from the gene of interest to levels that are detectable in order to determine the levels of messenger RNA in the tissue samples. Comparing the amount of messenger RNA in different plant samples is important because messenger RNA carries instructions that tell cells which proteins to produce, such as those responsible for generating cutin or wax. Less messenger RNA in the original tissue samples would indicate lower levels of gene expression, which ultimately determines cutin or wax production.

"The change in gene expression reflected what we observed," Nemacheck said. "In resistant plants, expression of the genes that control wax and cutin production was increased. Susceptible plants had a decrease in the expression of those genes."

Plants were determined to have become permeable through staining the tissue with a red dye that was placed on the larvae feeding sites. Resistant plants that were observed to have increased cutin production had slight red spotting along the leaves from the dye. But those that were susceptible absorbed the dye because cutin was lacking and the dye was able to seep into the plant's cells.
