Abstract:

To explore the molecular mechanism of plant resistance to various stress response, LeWRKY1 expressions in tomato seedlings, under treatment with B. cinerea, exogenous JA or SA, were explored by real time quantitative RT-PCR technology. The results showed that JA induced the expression of LeWRKY1, but SA did not. LeWRKY1 expression was up-regulated under B. cinerea infection. LeWRKY1 may involve in the tomato defense response to B. cinerea through JA dependent but SA independent signal pathway.
