ZmOST1 mediates abscisic acid regulation of guard cell ion channels and drought stress responses.

Journal of integrative plant biology - 1 Apr 2019

Wu Qiqi, Wang Mei, Shen Jianlin, Chen Donghua, Zheng Yu, Zhang Wei

Abstract excerpt

The phytohormone abscisic acid (ABA) is an important mediator in the drought response, participating in, among other processes, stomatal movements. In Arabidopsis thaliana, the serine/threonine protein kinase, OST1, regulates this response, but the function of its maize homolog has yet to be established. Here, we isolated ZmOST1 and show that its encoded protein indeed acts to regulate guard cell movement. ZmOST1...
