Increasing temperatures impact plant biochemistry, but the effects can be highly variable. Both external and internal factors modulate how plants respond to rising temperatures. One such factor is time of day or season temperature increase occurs. This timing significantly affects responses higher altering signaling networks affecting tolerance levels. overlaps between circadian high have been identified that could explain this sensitivity heat stress. ELF3, a clock component, functions as thermosensor. ELF3 regulates thermoresponsive hypocotyl elongation in part through its cellular localization. The depends on length polyglutamine region, explaining vary species. However, intersection system increased stress pervasive extends beyond overlap thermosensing. Here, we review network temperatures, stress, impacts mechanisms gene expression from transcription translation, highlighting intersections elevated response pathways signaling, focusing role

Plants measure daylength (photoperiod) to regulate seasonal growth and flowering. Photoperiodic flowering has been well studied, but less is known about photoperiodic growth. By using a mutant with defects in growth, we identified regulation pathway that functions long days parallel the canonical long-day photoperiod mechanism. This achieved by distinct mechanisms detect different photoperiods: The measures as duration of light intensity, whereas photosynthetic activity (photosynthetic period). can then independently control expression genes required for or demonstrates are dissociable, allowing them be coordinated across seasons.

Endogenous circadian clock integrates cyclic signals of environment and daily seasonal behaviors organisms to achieve spatiotemporal synchronization, which greatly improves genetic diversity fitness species. This review addresses recent studies on the plant system in field chronobiology, covering topics molecular mechanisms, internal external Zeitgebers, hierarchical regulation physiological outputs. The architecture involves autoregulatory transcriptional feedback loops, post-translational modifications core oscillators, epigenetic DNA histones. Here, light, temperature, humidity, elemental nutrients are summarized illustrate sensitivity timing cues. In addition, runs cell-autonomously, driving independent rhythms various tissues. oscillators responds each other with biochemical factors including calcium ions, mineral nutrients, photosynthetic products, hormones. We describe components sequentially expressed during a 24-h day that regulate rhythmic growth, aging, immune response, resistance biotic abiotic stresses.

The activities several key metabolic enzymes are regulated by light‐dependent post‐translational modifications (PTM) and have been studied at depth the level individual proteins. In contrast, global picture PTMome dynamics is lacking, leaving response large proportion cellular function undefined. Here, we investigated metabolome proteome Arabidopsis rosettes time resolved manner dissect their kinetic interplay, focusing on phosphorylation, lysine acetylation, cysteine‐based redox switches. Of over 24 000 PTM sites that were detected, more than 1700 changed during from light. While first changes, measured 5 min after onset illumination, occurred mainly chloroplasts, proteins other compartments coincided with full activation Calvin–Benson cycle synthesis sugars later timepoints. Our data reveal connections between metabolism PTM‐based throughout cell. comprehensive multiome profiling analysis provides insight into extent which photosynthesis reprograms cell adds powerful resource for dissection diverse processes context function.
