植物保卫细胞的激素信号转导网络研究进展

Phytohormone Signaling Network in Plant Guard Cells

保卫细胞可以感知并整合多种信号,以调节膨压和气孔运动,是研究植物激素信号互作的模式体系。本文对保卫细胞中植物激素脱落酸信号转导及其与其他植物激素的互作进行了综述,以期全面介绍保卫细胞植物激素信号转导网络的最新进展,并对今后的研究及其在作物生产中的潜在应用价值进行了展望。

Guard cell can sense and integrate multiple signals to regulate cell turgor and stomata movements. It is therefore regarded as a model system for studying the cross talk of phytohormones signaling. In this paper,ABA signal transduction and the cross talk of ABA signaling with other phytohormone signalings in guard cells are reviewed,to provide the emerging picture of phytohormone signaling network in guard cells. Future studies and potential application in crop production are also prospected.
