The role of Ca2+-CaM system in the jasmonate-induced defense response was studied using pharmacological methods on pea seedlings。Lower Ca2+ level and inhibition of CaM activity can be part of or all the elimination of jasmonate-induced PAL activity improvement and H2O2 accumulation。H2Oz-induced PAL activity improvement was also inhibited。It was showed that Ca2+ and CaM were jointly involved in jasmonate-induced defense reaction,and played an important role in the upstream and downstream of H2O2 signaling。
