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