Arabidopsis CRY1 and phyB are the primary blue red light photoreceptors mediating inhibition of hypocotyl elongation, respectively. Auxin is a pivotal phytohormone involved in promoting elongation. interact with stabilize auxin/indole acetic acid proteins (Aux/IAAs) to inhibit auxin signaling. The present study investigated whether might directly Response Factors (ARFs) regulate Protein-protein interaction studies demonstrated that physically ARF6 ARF8 through their N-terminal domains...
Light is a key environmental cue that fundamentally regulates plant growth and development, which mediated by the multiple photoreceptors including blue light (BL) photoreceptor cryptochrome 1 (CRY1). The signaling mechanism of Arabidopsis thaliana CRY1 involves direct interactions with CONSTITUTIVE PHOTOMORPHOGENIC (COP1)/SUPPRESSOR OF PHYA-105 stabilization COP1 substrate ELONGATED HYPOCOTYL 5 (HY5). H2A.Z an evolutionarily conserved histone variant, plays critical role in transcriptional...
Cryptochromes are photolyase-like, blue-light (BL) photoreceptors found in various organisms. Arabidopsis (Arabidopsis thaliana) cryptochromes (CRYs; CRY1, and CRY2) mediate many light responses including photoperiodic floral initiation. interact with COP1 SPA1, causing the stabilization of CONSTANS (CO) promotion FLOWERING LOCUS T (FT) transcription flowering. The AP2-like transcriptional factor TOE1 negatively regulates FT expression flowering by indirectly inhibiting CO activation...
Abstract Light serves as a crucial environmental cue which modulates plant growth and development, is controlled by multiple photoreceptors including the primary red light photoreceptor, phytochrome B (phyB). The signaling mechanism of phyB involves direct interactions with group basic helix‐loop‐helix (bHLH) transcription factors, PHYTOCHROME‐INTERACTING FACTORS (PIFs), negative regulators photomorphogenesis, COP1 SPAs. H2A.Z an evolutionarily conserved H2A variant plays essential roles in...
Arabidopsis cryptochrome 1 (CRY1) is an important blue light photoreceptor that promotes photomorphogenesis under light. The photoreceptors CRY2 and phototropin 1, the red/far-red phytochromes B A undergo degradation in response to red light, respectively. This study investigated whether how CRY1 might high-intensity (HBL). We demonstrated ubiquitinated degraded through 26S proteasome pathway HBL. found E3 ubiquitin ligase constitutive photomorphogenic (COP1) involved mediating HBL-induced...
