概要	To explore the role of JA or JA-regulated cellular process(es) in conditioning susceptibility, we used an Apple latent spherical virus (ALSV)-based virus-induced gene silencing (VIGS) technology to silence pea genes including LOX, AOS, AOC and 12-oxo-phytodienoic acid reductase (OPR). In LOX-, AOS-, AOC- or OPR-silenced pea plants, disease development induced by M. pinodes was remarkably reduced. Similarly, silencing of mRNA for LOX, AOS, AOC or OPR reduced the sensitivity to a phytotoxin, coronatine, which is believed to act through a JA-dependent process. On the basis of these results, it is conceivable that M. pinodes has evolved a strategy to condition susceptibility by manipulating the physiology of host cells, in particular JA-regulated cellular process(es), to promote disease development in pea.
