一氧化氮参与胞外ATP抑制泡桐花粉萌发和花粉管伸长
The involvement of nitric oxide in eATP-inhibited pollen germination and tube growth of Paulownia tomentosa
摘要
Abstract
The role of eATP and its relationship with nitric oxide(NO) in pollen germination and tube growth of Paulownia tomentosa were studied.The results showed that both eATP and NO donors(sodium nitroprusside) inhibited pollen germination and tube growth in a dose-dependence manner.Both NOS inhibitor(L-NAME) and NO scavenger(c-PTIO) partly reversed eATP-inhibited pollen germination and tube growth,indicating that the inhibitory effects of eATP on pollen germination and tube growth are related to NO generated by a NOS-like enzyme in pollen.关键词
