Molecular response of resistant and susceptible apple genotypes to Erwinia am…

The leaves of apple cultivars resistant (cv.Free Redstar) and susceptible (cv. Idared) to fire blight were infiltrated with Erwinia amylovora. After 24 hours, differential gene expression was analysed using cDNA-AFLP technique. The expression pattern in the resistant cultivar, especially up-regulated genes encoding proteins involved in hypersensitive reaction and controlled cell death (BAX inhi…
