▪ Abstract Circadian rhythms are found in most eukaryotes and some prokaryotes. The
mechanism by which organisms maintain these roughly 24-h rhythms in the absence of …

The interactive regulation between clock genes is central for oscillator function. Here, we
show interactions between the Arabidopsis clock genes LATE ELONGATED HYPOCOTYL …

Abscisic acid (ABA) is involved in regulating drought tolerance, and pyrabactin resistance-
like (PYL) proteins are known as ABA receptors. To elucidate the role of one of the ABA …

The second edition of this best-selling handbook is bigger, more comprehensive, and now
completely current. In addition to thorough updates to the discussions featured in the first …

The Arabidopsis pseudo-response regulator, APRR1, has a unique structural design
containing a pseudo-receiver domain and a C-terminal CONSTANS motif. This protein was …

Plant reproduction requires precise control of flowering in response to environmental cues.
We isolated a late-flowering Arabidopsis mutant, fkf1, that is rescued by vernalization or …

GIGANTEA (GI) is a plant specific nuclear protein and functions in diverse physiological
processes such as flowering time regulation, light signaling, hypocotyl elongation, control of …

Plants respond to day/night cycling in a number of physiological ways. At the mRNA level,
the expression of some genes changes during the 24-hr period. To identify novel genes …

In the cyanobacterium Synechococcus elongatus PCC 7942, the KaiA, KaiB and KaiC
proteins are essential for generation of circadian rhythms. We quantitatively analyzed the …
