Summary: This study reveals that SICKLE (SIC) acts as a novel negative regulator of photomorphogenesis by interacting with HY5 and PIF4 to mediate light signaling. SIC functions as a brake to prevent exaggerated light response and is degraded by COP1 in the dark to avoid excessive inhibition on photomorphogenesis at the beginning of light exposure.

Summary: Developmental outcomes in plants are shaped by the interplay between intrinsic and external factors, with light playing a key role in promoting stomatal development. The study by Wang et al. reveals that the light-regulated transcription factor HY5 activates the expression of STOMAGEN, a mesophyll-derived secreted peptide that stabilizes the master regulator of stomatal development in the epidermis, leading to enhanced stomatal production. This work highlights a molecular link between light signaling and stomatal development across different tissue layers.

Summary: Flavonols, a type of protective compounds, are regulated by light and other environmental factors. MYB12 has been identified as a key gene in Arabidopsis that regulates flavonol accumulation in response to light.

Summary: In this study, the researchers uncovered the essential role of WRKY32 in promoting photomorphogenesis in plants. WRKY32 directly activates the transcription of HY5 by binding to its promoter region, and is targeted for ubiquitination and degradation by COP1. Additionally, the mutation WRKY32(P409L) exhibits enhanced DNA binding ability and affects the expression of more genes.

Summary: DET1 and COP1 are two essential repressors of Arabidopsis photomorphogenesis, with DET1 regulating COP1 stability to reduce HY5 protein abundance and prevent HY5 from binding to hundreds of genomic loci, thereby avoiding hyper-photomorphogenic responses.

Summary: UV-B radiation is a segment of sunlight perceived by plants through the UVR8 photoreceptor. Monomeric UVR8 inhibits COP1's E3 ubiquitin ligase activity and destabilizes transcription factors. UVR8 signaling mechanisms initiate gene expression changes leading to UV-B-induced photomorphogenesis and acclimation.

Summary: The study investigates the cross-talk between light and ABA signaling in plants, identifying a physical interaction between transcription factors HY5 and ABI5. ABI5 may act as a negative regulator during photomorphogenesis, while HY5 acts as a positive regulator of ABA signaling. The findings provide insights into the mechanism of interaction between ABI5-HY5 that fine tunes the stress and developmental response in Arabidopsis.

Summary: This study investigates the effects of red- and blue-light irradiation on anthocyanin accumulation in strawberry. The results show that blue light, rather than red light, promotes the rapid accumulation of anthocyanins. It is discovered that the blue light photoreceptor FaCRY1, an E3 ubiquitin ligase FaCOP1, and light-responsive factor FaHY5 play important roles in regulating blue light-induced anthocyanin accumulation.

Summary: The photomorphogenic repressors BBX28 and BBX29 integrate light and brassinosteroid signaling by promoting BR-ENHANCED EXPRESSION transcriptional activity to precisely regulate seedling development. BBX28 and BBX29 physically interact with BEE1, BEE2, and BEE3 to enhance their binding to and activation of target genes, thus participating in the coordination of light and BR signaling.

Summary: BBX32 negatively regulates light signaling and promotes BR signaling to inhibit cotyledon opening in Arabidopsis. It integrates light and BR signals to regulate cotyledon opening during de-etiolation, interacting with both BZR1 and PIF3 to modulate the expression of common target genes.

Summary: The tomato transcription factor module BBX20/21-HY5 activates HY5 transcription, and the HY5 protein inhibits its own gene transcription, forming an autoregulatory negative feedback loop in UV-B signaling.

Summary: Plants undergo photomorphogenic development in the presence of light, which is repressed by the E3 ubiquitin ligase COP1. UVR8, the photoreceptor, inhibits COP1 through its interaction with COP1 and prevents its binding to substrates. BBX20-BBX22 are coactivators of HY5 and their stability increases after UV-B exposure. Mutants lacking BBX20, BBX21, and BBX22 are impaired in UV-B responses, but show unaffected induction of marker genes after UV-B exposure.

Summary: Ginkgo biloba leaves have a higher level of flavonoids at high altitudes, and UV-B radiation plays a key role in this increase. The transcription factor GbHY5 promotes flavonoid accumulation by interacting with GbMYB1 protein. This study provides insights into the molecular mechanisms of UV-B-induced flavonoid biosynthesis and the enhancement of flavonoid content in ginkgo leaves.

Summary: The study reveals that TZP acts as a key component in transmitting the FR light signal through direct interaction with HY5 and inhibition of COP1 interaction with HY5. Moreover, TZP and HY5 mutually upregulate each other in transmitting the FR light signal, indicating independent functions of TZP and HY5 in the pathway.
