22 <p>Our laboratory is mainly interested in jasmonic acid (JA)
23 signaling and regulation of JA-mediated plant responses to
26 <p><strong>Genetic dissection of the JA signaling
27 pathway</strong><br />
28 The fatty acid-derived plant hormone JA plays a key role in the
29 regulation of development, reproduction and systemic induced
30 resistance to herbivore attack. Compared to the five classic
31 plant hormones, relatively little is known about the molecular
32 mechanisms governing the JA action, especially in the area of
33 JA-mediated defense responses to insects. Using tomato as a
34 genetic model, we have been able to identify several mutants
35 that are deficient in systemic defense responses.
36 Interestingly, map-based cloning of these mutants identified
37 genes that are involved in JA biosynthesis and signaling.
38 Grafting experiments using a JA biosynthesis mutant
39 (<em>spr2</em>) and a JA signaling mutant (<em>jai1</em>)
40 demonstrated that JA or a derivative, rather than the
41 18-amino-acid peptide systemin is the long-distance mobile
42 "wound signal" for systemic defense responses and that the
43 biosynthesis of JA is regulated by systemin. A long-term goal
44 of our research is to identify most, if not all, of the genes
45 that are involved in systemin/JA-mediated wound response
46 pathway and elucidate how these genes are regulated.</p>
48 <p><strong>Identification of agriculturally important genes in
49 rice and tomato</strong><br />
50 Another aspect of our research is to identify agriculturally
51 important genes in the model system of rice and tomato, using a
52 map-based cloning approach.</p>
