Light-regulated transcriptional networks in higher plants
Plants have evolved complex and sophisticated transcriptional networks that mediate developmental changes in response to light. These light-regulated processes include seedling photomorphogenesis,Expand

COP1 and DET1 are among the first repressors of photomorphogenesis to be identified, more than 20 years ago. Discovery of these repressors as conserved regulators of the ubiquitin-proteasome systemExpand
Genome Analysis and Functional Characterization of the E2 and RING-Type E3 Ligase Ubiquitination Enzymes of Arabidopsis1[W]
Attachment of ubiquitin to substrate proteins is catalyzed by the three enzymes E1, E2 (ubiquitin conjugating [UBC]), and E3 (ubiquitin ligase). Forty-one functional proteins with a UBC domain andExpand
Arabidopsis CULLIN4-Damaged DNA Binding Protein 1 Interacts with CONSTITUTIVELY PHOTOMORPHOGENIC1-SUPPRESSOR OF PHYA Complexes to Regulate Photomorphogenesis and Flowering Time[C][W]
CUL4-DDB1 associates with COP1-SPA complexes via its linker protein DDB1 to regulate photomorphogenesis and possibly also flowering time under short-day conditions. The CUL4-DDB1-COP1-SPAExpand
Direct roles of SPEECHLESS in the specification of stomatal self-renewing cells
A complex network makes simple pores Stomata, the pores found on the surface of plant leaves, form at intervals from stem cells. Development of stomata is controlled by the SPEECHLESS transcriptionExpand

Light is an important environmental signal that regulates diverse growth and developmental processes in plants. In these light-regulated processes, multiple hormonal pathways are often modulated byExpand
Conversion from CUL4-based COP1–SPA E3 apparatus to UVR8–COP1–SPA complexes underlies a distinct biochemical function of COP1 under UV-B
Significance CONSTITUTIVE PHOTOMORPHOGENESIS 1 (COP1) is a well-conserved multifunctional protein in both plants and animals. Depending on the context, COP1 can have distinct roles, such as anExpand
Coordinated transcriptional regulation underlying the circadian clock in Arabidopsis
The circadian clock controls many metabolic, developmental and physiological processes in a time-of-day-specific manner in both plants and animals. The photoreceptors involved in the perception ofExpand
Stomatal development: a plant's perspective on cell polarity, cell fate transitions and intercellular communication
The plant stomatal lineage manifests features common to many developmental contexts: precursor cells are chosen from an initially equivalent field of cells, undergo asymmetric and self-renewingExpand
Arabidopsis FHY3 and HY5 Positively Mediate Induction of COP1 Transcription in Response to Photomorphogenic UV-B Light[C][W][OA]
In UV-B–induced photomorphogenesis in Arabidopsis, COP1 is a UV-B–inducible gene and FHY3 and HY5 directly activate COP1, dependent on UV-B, by binding to the COP1 promoter to ensure photomorphogenicExpand
