Blue light-induced SRS5 promotes photomorphogenesis by directly activating photomorphogenesis-promoting genes such as HY5, BBX21 and BBX22, but COP1 directly targets SRS5 for degradation in the dark. Plant seedlings undergo distinct developmental processes in the dark and in the light. Several genes, including ELONGATED HYPOCOTYL5 (HY5), B-BOX PROTEIN21 (BBX21), and BBX22, have been identified as photomorphogenesis-promoting factors in Arabidopsis thaliana; however, the overexpression of these…

Auxin abolishes SHI-RELATED SEQUENCE5-mediated inhibition of lateral root development in Arabidopsis.

The data reveal that SRS5 negatively regulates LR formation by repressing the expression of LBD16 and LBD29 and that auxin releases this inhibitory effect through ARF7 and ARF19.

COP1 mediates light-dependent regulation of flavonol biosynthesis through HY5 in Arabidopsis.

Modulation of BIN2 kinase activity by HY5 controls hypocotyl elongation in the light

It is demonstrated that HY5 enhances the activity of GSK3-like kinase BRASSINOSTEROID-INSENSITIVE 2 (BIN2), a key repressor of brassinosteroid signaling, to repress hypocotyl elongation.

Cryptochrome 2 competes with COP1 substrates to repress COP1 ubiquitin ligase activity during Arabidopsis photomorphogenesis

It is shown that CRY2 inhibits COP1 by displacing degradation substrates from COP1, and the previously unknown interaction between SPA1-WD and CCT2 occurs via the VP motif in CRy2, suggesting structural similarities in the VP-binding pockets of COP1- WD40 and SPA 1-WD40 domains.

Bioinformatics analysis of BBX family genes and its response to UV-B in Arabidopsis thaliana

ABSTRACT The B-box proteins (BBXs) are a family of zinc finger proteins containing one/two B-box domain(s), which play important roles in plant growth and development. Though the Arabidopsis thaliana

B-box proteins: pivotal players in light-mediated development in plants.

This review summarizes and highlights the recent findings concerning the critical regulatory functions of BBXs in photoperiodic flowering, light signal transduction and light-induced pigment accumulation and their molecular modes of action at the transcriptional and posttranslational levels in plants.

HY5: A Pivotal Regulator of Light-Dependent Development in Higher Plants

ELONGATED HYPOCOTYL5 (HY5), a bZIP-type transcription factor, acts as a master regulator that regulates various physiological and biological processes in plants such as photomorphogenesis, root

Plant photoreceptors and their signaling components compete for binding to the ubiquitin ligase COP1 using their VP-peptide motifs

Analysis of why many COP1-interacting transcription factors and photoreceptors harbor sequence-divergent Val-Pro (VP) peptide motifs demonstrates that VP motifs enable different light signaling components to bind to the WD40 domain of COP1 with various binding affinities.

CONSTITUTIVELY PHOTOMORPHOGENIC1 promotes ABA-mediated inhibition of post germination seedling establishment.

It is shown that light availability critically influences the ABA sensitivity during early seedling development and COP1 positively regulates ABA signaling to inhibit post germination seedling establishment under stress.

Systematic analysis and identification of regulators for SRS genes in Capsicum annuum

SHI-related sequence (SRS) transcription factors are essential for plant development and growth regulation, phytohormone biosynthesis and stress response. The SRS gene family was analyzed in several



BBX21, an Arabidopsis B-box protein, directly activates HY5 and is targeted by COP1 for 26S proteasome-mediated degradation

It is shown that BBX21 binds to the T/G-box in the ELONGATED HYPOCOTYL 5 (HY5) promoter and directly activates HY5 expression in the light, indicating thatBBX21 is a pivotal component involved in the COP1-HY5 regulatory hub.

Targeted destabilization of HY5 during light-regulated development of Arabidopsis

It is shown that the abundance of HY5 is directly correlated with the extent of photomorphogenic development, and that the COP1–HY5 interaction may specifically target HY5 for proteasome-mediated degradation in the nucleus.

The phytochrome A-specific signaling intermediate SPA1 interacts directly with COP1, a constitutive repressor of light signaling in Arabidopsis.

The results suggest that SPA1 may function to link the phytochrome A-specific branch of the light signaling pathway to COP1, providing molecular support for the hypothesis that COP1 is a convergence point for upstream signaling pathways dedicated to individual photoreceptors.

Two interacting bZIP proteins are direct targets of COP1-mediated control of light-dependent gene expression in Arabidopsis.

It is proposed that COP1 mediates light control of gene expression through targeted degradation of multiple photomorphogenesis-promoting transcription factors in the nucleus.

COP1-Mediated Degradation of BBX22/LZF1 Optimizes Seedling Development in Arabidopsis1[W][OA]

It is found that during skotomorphogenesis, the expression of BBX22 needs to be tightly regulated at both transcriptional and posttranslational levels, which is crucial for plants to maintain optimal growth when grown in the dark as to respond to seasonal changes in daylength.

LZF1/SALT TOLERANCE HOMOLOG3, an Arabidopsis B-Box Protein Involved in Light-Dependent Development and Gene Expression, Undergoes COP1-Mediated Ubiquitination[W]

STH3 is identified as a positive regulator of photomorphogenesis acting in concert with STH2 and HY5, while also being a target of COP1-mediated ubiquitination.

UV-B-Responsive Association of the Arabidopsis bZIP Transcription Factor ELONGATED HYPOCOTYL5 with Target Genes, Including Its Own Promoter[W][OPEN]

This work shows thatUV-B enhances the binding of HY5 to the promoters of UV-B-responsive genes and that HY5, as well as its homolog HYH, interact directly with the cis-regulatory T/G-box of the HY5 promoter to mediate UV- B-induced transcriptional activation ofHY5.

A crucial role for a chromatin remodeling factor in repressing photomorphogenesis is revealed and it is demonstrated that transcription factor–mediated recruitment of chromatin-remodeling machinery is important for plant development in response to changing light environments.

Analysis of Transcription Factor HY5 Genomic Binding Sites Revealed Its Hierarchical Role in Light Regulation of Development[W]

It is demonstrated that in vivo association of HY5 with promoter targets is not altered under distinct light qualities or during light-to-dark transition, and a model in which HY5 is a high hierarchical regulator of the transcriptional cascades for photomorphogenesis is supported.
