摘要：

To determine whether abscisic acid (ABA) accumulation in endosperms of water-limited maize (Zea mays L.) plants is from synthesis in maternal plant organs or from intraendosperm synthesis, plants heterozygous for viviparous (vp) genes were self-pollinated to create endosperm genotypes capable (+/-/-; +/+/-; +/+/+) or incapable (-/-/-) of carotenoid and ABA synthesis. The mutants vp2, vp5, and vp7, each in W22 inbred background, were utilized. Both in wild-type endosperms capable of ABA synthesis and in mutants incapable of ABA synthesis, ABA concentrations at 15 days after pollination were substantially increased in response to plant water deficit. We conclude that ABA synthesis in maternal organs was the source of ABA that accumulated in endosperms in response to plant water deficit.
