A series of hormone mutants, transgenetic plants and inhibitors were used to investigate the roles of ethylene (ET), jasmonic acid (JA) and salicylic acid (SA) pathways as well as their crosstalk during the interaction between tomato plants and AAL(Alternaria stem canker disease in tomato), and programmed cell death (PCD) induced by AAL-toxins.It turned out that both the ET and JAI1 receptor-dependent JA signalling pathways are necessary for susceptibility, while SA response promotes resistance to AAL infection.In addition, the role of JA in susceptibility to AAL is partly dependent on ET biosynthesis and perception, while the SA pathway enhances resistance to AAL and antagonizes the ET response.In general, ET, JA, and SA each on their own can influence the susceptibility of tomato to AAL.Moreover, the functions of JA and SA in susceptibility to the pathogen are correlated with the enhanced or decreased action of ET, respectively.
