Summary: The development of stomata in plants is regulated by the blue light photoreceptor CRY1 and the G-protein AGB1, with AGB1 inhibiting the DNA-binding activity of SPCH and CRY1 promoting it, leading to the expression of genes promoting stomatal development. This antagonistic regulation by CRY1 and AGB1 may allow plants to balance light and G-protein signaling, optimizing stomatal density and pattern.

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: 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: 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: Plant G proteins play a key role in signaling transduction pathways, with AGB1 interacting with the GA pathway suppressor MYB62 to regulate plant growth. The study shows that MYB62 is downstream of AGB1 in the GA pathway, and AGB1 negatively regulates MYB62 activity by affecting its binding on the promoter of the GA degradation gene GA2ox7.

Summary: This study reveals the interaction between the alpha-subunit of the cone-specific heterotrimeric G protein and the photolyase homolog in European robin, and confirms its existence in living cells. These findings support the important role of light-induced radical-pair formation in the bird's retina, which may be the first biochemical signaling step in magnetoreception.

Summary: In Arabidopsis, the SPA2 protein functions as a suppressor of photomorphogenesis under different light conditions. The central coiled-coil and C-terminal WD-repeat domains of SPA2 play a critical role in repressing seedling de-etiolation, cotyledon unfolding, and promoting hypocotyl negative gravitropism. Light-activated phyA, phyB, cry1, and COP1 interact directly with SPA2 to rapidly suppress its activity in response to far-red, red, and blue light treatments.

Summary: Researchers have identified three bZIP transcription factors (bZIP16, bZIP68, and GBF1) that play important roles in regulating chloroplast establishment. The activity of these factors is dependent on the redox status of a conserved cysteine residue, allowing for fine-tuning of light-responsive gene expression. In addition, they have been identified as novel interaction partners of the blue-light cryptochrome photoreceptors (CRY).

Summary: The PIF3/HY5 module antagonistically regulates protochlorophyllide synthesis in the dark, with the B-BOX protein BBX11 acting downstream to modulate gene expression. BBX11 directly influences the greening ability of seedlings exposed to light, while also impacting protochlorophyllide accumulation and photobleaching. The expression of BBX11 is regulated by both PIF3 and HY5, highlighting its importance in balancing plant growth in dark and light conditions.

Summary: Arabidopsis cryptochrome 1 (CRY1) undergoes degradation through ubiquitination and the 26S proteasome pathway in response to high-intensity blue light (HBL), involving E3 ubiquitin ligases COP1 and LRBs. Additionally, a blue-light inhibitor of cryptochromes 1 interacts with CRY1 in a blue-light-dependent manner to inhibit its dimerization/oligomerization and suppress HBL-induced degradation of CRY1.

Summary: This study investigated the development of cucumber fruit spines and found that CsTs gene can influence their development. Transcriptome analysis revealed differential gene expression associated with fruit spine development at different stages. Additionally, significant differences were observed between mutant and wild-type spines at stage III. Functional and interaction analyses suggested that CsTs may regulate fruit spine development by influencing cell polarity.

Summary: This study developed immune scoring systems focusing on B7-H3, B7-H4, and HHLA2, and demonstrated their potential in predicting survival and immunotherapeutic efficacy for gallbladder cancer (GBC). The results showed that these immune scoring systems were associated with worse clinicopathological stage and unfavorable prognosis in postoperative survival. Additionally, novel prediction models based on immune stratification and TNM staging showed excellent discrimination ability in predicting survival and immunotherapeutic efficacy for GBC patients.

Summary: Selenium is an essential trace element for human immune regulation and disease prevention. In plants, organic selenium compounds promote plant growth, improve nutritional quality, and play important roles in plant ecosystems. Selenium accumulation plants release selenium-containing compounds that promote the growth of selenium accumulators but inhibit the growth and distribution of non-selenium accumulators.
