Abstract

Drought stress has been extensively studied for its effect on the downstream signaling cascade and stress-responsive gene expression, but understanding the process has remained elusive. Recently, Zhao et al. identified DROOPY LEAF1 (DPY1) as an osmosensor and revealed a novel mechanism of DPY1-STRESS ACTIVATED PROTEIN KINASE6 (SAPK6)-mediated drought stress signaling in higher plants.

摘要

干旱胁迫对下游信号级联和应激响应基因表达的影响已得到广泛研究，但对其作用机制仍难以捉摸。最近，Zhao 等人将 DROOPY LEAF1 (DPY1) 鉴定为一种渗透传感器，并揭示了 DPY1-STRESS ACTIVATED PROTEIN KINASE6 (SAPK6) 介导的高等植物干旱胁迫信号转导的新机制。
