HPGDS and infection: These proteins include nine glutathione S-transferases (GSTs), a ubiquitous class of enzymes that are capable of detoxifying xenobiotics51; three heat shock proteins (HSPs), of which RTM2 protein (Glyma.04G129900) functions in phloem to redistrict long-distance movements of virus52, another HSP gene, Glyma.04G108500, that was strongly induced by 32.3-fold following HG type 2.5.7 infection in S54 but that was insensitive in S67; and eight protease inhibitors that have the capacity to interfere with the digestive processes of insects, leading to resistance reactions53.
