A small subset of basic helix–loop–helix transcription factors called PIFs (phytochrome-
interacting factors) act to repress seed germination, promote seedling skotomorphogenesis …

Plants, like other eukaryotes, rely on proteolysis to control the abundance of key regulatory
proteins and enzymes. Strikingly, genome-wide studies have revealed that the ubiquitin-26S …

Artemisinin, a sesquiterpene compound synthesized and stored in the glandular trichome of
Artemisia annua leaves, has been used to treat malaria. Previous studies have shown that …

Anthocyanins are natural pigments that accumulate only in light‐grown and not in dark‐
grown Arabidopsis plants. Repression of anthocyanin accumulation in darkness requires the …

Background An important contributing factor to the success of terrestrial flowering plants in
colonizing the land was the evolution of a developmental strategy, termed …

The transcriptional regulator CONSTANS (CO) promotes flowering of Arabidopsis under
long summer days (LDs) but not under short winter days (SDs). Post‐translational regulation …

Background The covalent attachment of ubiquitin to a substrate protein changes its fate.
Notably, proteins typically tagged with a lysine48-linked polyubiquitin chain become …

Cryptochromes (CRYs) are blue-light photoreceptors that mediate various light responses in
plants and animals. The signaling mechanism by which CRYs regulate light responses …

Abstract CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1) is a negative regulator of
photomorphogenesis in Arabidopsis thaliana. COP1 functions as an E3 ubiquitin ligase …

The Arabidopsis thaliana RING-type E3 ligase KEEP ON GOING (KEG) is a negative
regulator of abscisic acid (ABA) signaling. Seedlings homozygous for T-DNA insertions in …
