茉莉酸类在诱导稻的颖花开放中的作用机理
基本信息
结项摘要
Exogenous jasmonic acid (JA) and methyl jasmonates (MeJA) significantly induced floret opening in rice, wheat and other of gramineous plant. Linolenic acid (LA) and other precursors of JA biosynthesis, also have the effect. During floret opening, endogenous JA was measured in stamens, pistils, lodicules and glumes in wheat. The results indicated that JA play an important role in floret opening.Salicylic acid (SA) coild inhibit the induction of MeJA in floret opening; while MeJA could relieve the inhibition of SA on MeJA induced floret opening.MeJA could enhance CO2 evolution. MeJA induction on rice floret opening mainly relied on glycolysis pathway and tricarboxylic acid cycle (EMP-TAC), and depended on cytochrome pathway (CP) for adenosine triphosphate (ATP). Ca2+-CaM also participated in MeJA induced floret opening.
