Abstract

Environmental stresses restrict plant growth and development and decrease crop yield. The circadian clock is associated with the ability of a plant to adapt to daily environmental fluctuations and the production and consumption of energy. Here, we investigated the role of Arabidopsis Universal Stress Protein (USP; At3g53990) in the circadian regulation of nuclear clock genes. The Arabidopsis usp knockout mutant line exhibited critically diminished circadian amplitude of the central oscillator CIRCADIAN CLOCK ASSOCIATED 1 (CCA1) but enhanced the amplitude of TIMING OF CAB EXPRESSION 1 (TOC1). However, the expression of USP under the control of its own promoter restored the circadian timing of both genes, suggesting that USP regulates the circadian rhythm of Arabidopsis central clock genes, CCA1 and TOC1.

通用应激蛋白调控拟南芥中枢振荡基因的昼夜节律

环境胁迫限制了植物的生长发育，降低了作物产量。生物钟与植物适应日常环境波动以及能源生产和消耗的能力有关。在这里，我们研究了拟南芥通用应激蛋白（USP；At3g53990）在核时钟基因的昼夜节律调节中的作用。拟南芥usp敲除突变株系表现出中枢振荡器昼夜节律相关1（CCA1）的昼夜节律振幅严重降低，但CAB表达1（TOC1）的时序振幅增强。然而，USP在其自身启动子控制下的表达恢复了这两个基因的昼夜节律，表明USP调节拟南芥中央时钟基因CCA1和TOC1的昼夜节律。
