Abstract excerpt

In Arabidopsis, resistance to Turnip Crinkle Virus (TCV) depends on the resistance (R) gene, HRT, and the recessive locus rrt. Resistance also depends on salicylic acid (SA), EDS1, and PAD4. Exogenous application of SA confers resistance in RRT-containing plants by increasing HRT transcript levels in a PAD4-dependent manner. Here we report that reduction of oleic acid (18:1) can also induce HRT gene expression...
