Orchestration of GSM1 and MOS2 in microRNA biogenesis and plant growth in Arabidopsis.

Plant physiology - 1 Sept 2026

Wang Lingyu, Song Yu, Yan Jiawen, Yang Xiao, Zheng Min, Hsu Yi-Feng

Abstract excerpt

GSM1, a potential DEAH-box RNA helicase, is involved in the glucose-abscisic acid signaling pathway and RNA silencing. Here, MOS2 is identified as interacting with GSM1 in the nucleus, and the G-patch domain of MOS2 promoted RNA helicase activity of GSM1 in vitro. In gsm1-2, reduced levels of several microRNAs (miRNAs) and increased levels of their respective target genes were observed. The lack of MOS2 in gsm1-2...
