Development of a lesion-mimic phenotype in a transgenic wheat line overexpressing genes for pathogenesis-related (PR) proteins is dependent on salicylic acid concentration.

Abstract excerpt

In the course of coexpressing genes for pathogenesis-related (PR) proteins for a class IV chitinase and an acidic glucanase in transgenic wheat plants, we regenerated a wheat line that developed necrotic lesions containing dead cells in the T2 and subsequent generations. Lesion spots were detecte...
