LNK1 and LNK2 Are Transcriptional Coactivators in the <i>Arabidopsis</i> Circadian Oscillator

Abstract

The plant circadian clock consists of multiple interlocked transcriptional feedback\nloops. This work shows that LNK1 and LNK2, two\nNIGHT LIGHT–INDUCIBLE AND CLOCK-REGULATED genes, encode\ntranscriptional coactivators that physically interact in the nucleus with multiple\nMyb transcription factors (CCA1, LHY, RVE4, and RVE8) and are necessary for full\ntranscriptional induction of PRR5 and TOC1 by\nRVE8.
