Cold-induced degradation of core clock proteins implements temperature compensation in the Arabidopsis circadian clock.

Abstract excerpt

The period of circadian clocks is maintained at close to 24 hours over a broad range of physiological temperatures due to temperature compensation of period length. Here, we show that the quantitative control of the core clock proteins TIMING OF CAB EXPRESSION 1 [TOC1; also known as PSEUDO-RESPONSE REGULATOR 1 (PRR1)] and PRR5 is crucial for temperature compensation in Arabidopsis thaliana. The prr5 toc1 double...
