简介
Many studies in dicotyledonous plants have shown that jasmonates, including jasmonic acid (JA) and methyl jasmonate, are important signal molecules involved in induced resistance to pathogen infection and insect herbivory. However, very little genetic and molecular evidence is available to demonstrate their role in host defense response of rice and other economically important monocot plants. In this study, we have shown that exogenous application of JA was able to activate defense gene expression and local induced resistance in rice seedlings against the rice blast fungus (Magnaporthe grisea). Furthermore, we have characterized a pathogen-inducible rice OsAOS2 gene (which encodes allene oxide synthase, a key enzyme in the JA biosynthetic pathway) and examined the role of endogenous JA in rice defense response through transgenic manipulation of the JA biosynthesis. Sequence analysis indicated …
