Figure 1. Hessian fly induces higher levels of glutathione in wheat tissues at the feeding site in resistant plants, but did not affect the ratio of GSH/GSSG.

Black and grey bars represent data from susceptible (Newton) and resistant (Molly) plants, respectively. GSH+GSSG represent changes in the abundance of total glutathione, whereas GSSG represents changes in abundance of oxidized glutathione. The bottom panel represents the ratio of GSSG/GSH.
