Summary: Plant growth is regulated by light and gibberellin (GA) signals, which have opposite effects on hypocotyl elongation. This study reveals that GA promotes hypocotyl elongation through the activation of ABI4. DELLAs interact with ABI4 and inhibit its DNA-binding activity, while ABI4 interacts with HY5, a key factor in light signaling, to regulate the expression of GA catabolism genes and modulate GA levels, thus controlling hypocotyl elongation.

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: The study found that UV-A (UVA) and UV-B irradiation can promote anthocyanin biosynthesis in Hujingmilu peach fruit, with a combination of the two having additional effects. UV irradiation can induce the expression of light signaling-related genes in a short period of time, especially before visible color changes occur. PpHY5 in peach regulates anthocyanin synthesis in the UVA and UVB light transduction pathway by upregulating the expression of transcription factor genes.

Summary: Research shows that light can rapidly induce the expression of miR163, and its light-inducible response is related to the regulation downstream of the HY5 gene, which directly affects the expression of miR163 promoter. Overexpression of miR163 can rescue the defective primary root elongation of hy5 seedlings, while overexpression of miR163 target PXMT1 inhibits primary root elongation.

Summary: The safe and smooth functioning of photosynthesis in plants is ensured by various regulatory mechanisms, including chloroplast movements and quenching of electronic excitations. A study using fluorescence lifetime imaging microscopy of Arabidopsis thaliana leaves found that these mechanisms operate over a wide range of light intensities. Impaired chloroplast movements do not affect photoprotection at the molecular level, indicating the one-way information flow from the photosynthetic apparatus to the cellular level. The presence of zeaxanthin is necessary and sufficient for the full development of photoprotective quenching in plants.

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: Light plays a crucial role in plant morphology and crop yield. This study reveals that light regulates tomato bud outgrowth through the HY5 signaling pathway and brassinosteroid signaling pathway.

Summary: This study reveals the important role of beta CA3 in plant basal immunity under high CO2 in susceptible crops, which differs from its role in Arabidopsis thaliana. The activation of basal immunity by beta CA3 is regulated transcriptionally by the transcription factor NAC43 and post-translationally by the receptor-like kinase GRACE1, indicating a specific mechanism in different plant species. Additionally, the involvement of cell wall metabolism/integrity in beta CA3-mediated basal immunity under both CO2 conditions suggests potential targets for disease management strategies in changing climate.

Summary: This study found that rosmarinic acid can enhance thermotolerance in tomatoes by promoting the transcript abundance and enzyme activity of enzymatic antioxidants. Additionally, rosmarinic acid activates the antioxidant system and modulates cellular redox homeostasis. RNA-seq data also suggests that transcriptional regulation is involved in rosmarinic acid-mediated thermotolerance. These findings not only establish a direct link between rosmarinic acid and plant thermotolerance, but also offer an attractive approach to protecting crop plants from high-temperature damage in a future of global warming.

Summary: In this study, we investigated the molecular mechanism of two genes, SlSEC1 and SlC3H39, in plant cold tolerance using knockout and overexpression tomato lines. We found that SlC3H39 negatively regulates cold tolerance by post-transcriptional regulation, while SlSEC1 negatively regulates cold tolerance by controlling the function and stability of SlC3H39 protein. Furthermore, we discovered that SlC3H39 regulates the expression of cold-responsive genes through binding to the mRNA 3' untranslated region.

Summary: The post-translational modification of proteins enables cells to respond promptly to dynamic stimuli by controlling protein functions. In this study, researchers found that SlSPY plays a positive regulatory role in fruit ripening in tomatoes by changing the ethylene response. They also discovered that SlSPY interacts with a central regulator of ethylene signaling, SlEIN2, promoting its stability and nuclear accumulation. These findings reveal a novel regulatory function of SlSPY in fruit ripening and provide new insights into the role of the SlSPY-SlEIN2 module in tomato fruit ripening.

Summary: Post-translational modifications have significant effects on protein functions, with O-glycosylation playing a crucial role in controlling biological processes in plants. Plants have unique types of O-glycosylation, different from animals and prokaryotes, that regulate transcription, localization, and protein degradation. O-glycosylation is complex due to the various types of O-glycan, prevalence of Hyp, Ser, and Thr residues, and variable sugar linkages. It specifically affects development and environmental acclimatization in diverse physiological processes.

Summary: Plants exhibit dynamic changes in molecular structures under fluctuating light conditions, with light playing a crucial role in plant growth and morphogenesis. Although there have been advances in understanding the mechanism of nutrient acquisition and assimilation, the impact of light on ion uptake remains a question. Studies on model plants indicate that light affects nutrient utilization in roots through a complex regulatory network, but the molecular mechanisms underlying the effects of light on these processes in crop plants are still incomplete. In this review, the effects of light on nutrient uptake and utilization in horticultural crops are discussed for the purpose of optimizing crop productivity and increasing fertilizer efficiency.
