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.

Keywords: Arabidopsis; CCA1; TOC1; USP; circadian clock; stress-related gene.
