Study the Action of Jasmonic Acid in Plant Senescence

The biosynthetic pathway of jasmonic acid and the expression situations of each enzyme in the synthesis process in the senescence process were introduced at first.Then the research progresses on the correlation between jasmonic acid and the senescence hormones of ethene and abscisic acid in the signal transduction pathway,the promotion of jasmonic acid on the leaf senescence and its inhibition to the photosynthesis of plants,the activation of the senescence gene SAGs by jasmonic acid and so on were sum up.
