Abstract Plants have evolved specific temperature preferences, and shifts above this range cause heat stress with detrimental effects such as physiological disruptions, metabolic imbalances, growth arrest. To reduce damage, plants utilize the shock response (HSR), signaling cascades that activate factors (HSFs), transcription control stress-responsive transcriptome for activation of protective measures. While core HSR is well studied, we still know relatively little about perception signal integration or crosstalk other pathways. In last few years, however, significant progress has been made in area, which summarized here. It emerged plant hormones brassinosteroids (BRs) abscisic acid (ABA) contribute to tolerance by impacting modes activity HSFs. Also, began understand sensed different cellular compartments events nucleus, nuclear condensate formation via liquid–liquid phase separation, play a key role. future, it will be important explore how these multilayered are utilized environmental context developmental stage determine outcome on development.

Chinese fir (Cunninghamia lanceolata) is an important fast-growing tree species for timber production and ecological protection in China. Yet, its tissue culture seedling propagation hampered by low proliferation poor quality. Light quality vital growth, but the regulatory mechanisms remain poorly understood. In this study, a transcriptome metabolome were integrated to explore light quality’s effects on adventitious shoot of tissue-cultured seedlings. The seedlings grown under red, green, blue, composite light-emitting diode conditions, with white as control. Results showed that blue blue-dominant enhanced promoting auxin cytokinin increased biomass. Red promoted height, leaf area, carotenoid content due elevated gibberellin reduced auxins levels inhibited hormonal imbalances. Green abscisic acid suppressed growth. Transcriptome analyses identified key pathways including plant hormone signal transduction, photosynthesis, flavonoid biosynthesis. Weighted gene co-expression network analysis (WGCNA) four genes regulated further modulated biosynthesis signaling transduction. This research provided insights optimizing contributing sustainable plantation management.

The effect of different light colors on the concentration albumins and globulins during black bean (Phaseolus vulgaris L.) germination was evaluated with an RGB LED lighting system. This study aimed to determine how spectral composition influences protein content across stages. Black seeds were germinated under six sources (red, green, blue, white, violet, cyan), fractions quantified by Bradford’s method. results showed that blue cyan increased albumins. Blue, for compared solar conditions both fractions. positive correlation between these specific wavelengths suggests a metabolic adaptation exposure. These findings highlight potential controlled enhance nutritional quality beans, supporting their application as functional food ingredients. Additionally, this underscores importance photobiological modulation in seed germination, opening new possibilities optimizing plant-based sources. Future research could explore mechanisms behind variations implications production nutrition.

Abstract The phytochrome (phy) family of sensory photoreceptors modulates developmental programs in response to ambient light. Phys also control gene expression part by directly interacting with the bHLH class transcription factors, PHYTOCHROME-INTERACTING FACTORS (PIFs), and inducing their rapid phosphorylation degradation. Several kinases have been shown phosphorylate PIFs promote However, phosphatases that dephosphorylate are less understood. In this study, we describe 4 regulatory subunits Arabidopsis (Arabidopsis thaliana) protein PHOSPHATASE 2A (PP2A) (B′α, B′β, B″α, B″β) interact PIF3 yeast 2-hybrid, vitro vivo assays. pp2ab″αβ b″αβ/b′αβ mutants display short hypocotyls, while overexpression B induces longer hypocotyls compared wild type (WT) under red light-induced degradation is faster quadruple mutant WT. Consistently, immunoprecipitated PP2A A PIF3-MYC vitro. An RNA-sequencing analysis shows B″α B″β alter global (PIF1, PIF3, PIF4, PIF5) epistatic these regulating hypocotyl elongation Collectively, data show an essential function dephosphorylating modulate photomorphogenesis Arabidopsis.
