Drought is one of the major constraints to rain-fed agricultural production, especially under climate change conditions. Plants evolved an array adaptive strategies that perceive stress stimuli and respond these signals through specific mechanisms. Abscisic acid (ABA) a premier signal for plants drought plays critical role in plant growth development. ABA triggers variety physiological processes such as stomatal closure, root system modulation, organizing soil microbial communities, activation transcriptional post-transcriptional gene expression, metabolic alterations. Thus, understanding mechanisms ABA-mediated responses ensuring crop yield global food security. In this review, we highlighted how adjust perception, levels ABA- drought-related genes, regulation pathways alter at both cellular whole level. Understanding synergetic will strengthen our knowledge develop stress-resilient crops integrated advanced biotechnology approaches.

We present unresolved questions in plant abiotic stress biology as posed by 15 research groups with expertise spanning eco-physiology to cell and molecular biology. Common themes of these include the need better understand how plants detect water availability, temperature, salinity, rising carbon dioxide (CO2) levels; environmental signals interface endogenous signaling development (e.g. circadian clock flowering time); this integrated controls downstream responses stomatal regulation, proline metabolism, growth versus defense balance).

Flowering is a critical agricultural trait that substantially affects tomato fruit yield. Although drought stress influences flowering time, the molecular mechanism underlying drought-regulated in remains elusive. In this study, we demonstrated loss of function OPEN STOMATA 1 (SlOST1), protein kinase essential for abscisic acid (ABA) signaling and abiotic responses, lowers tolerance plants to stress. slost1 mutants also exhibited late phenotype under both normal conditions. We established SlOST1 directly interacts with phosphorylates NAC (NAM, ATAF CUC)-type transcription factor VASCULAR PLANT ONE-ZINC FINGER (SlVOZ1), at residue serine 67, thereby enhancing its stability nuclear translocation an ABA-dependent manner. Moreover, uncovered several SlVOZ1 binding motifs from DNA affinity purification sequencing analyses revealed can bind promoter major flowering-integrator gene SINGLE FLOWER TRUSS promote transition response drought. Collectively, our data uncover role SlOST1-SlVOZ1 module regulating offer insights into novel strategy balance flowering.

Correct measurement of environmental parameters is fundamental for plant fitness and survival, as well timing developmental transitions, including the switch from vegetative to reproductive growth. Important that affect flowering time include day length (photoperiod) temperature. Their response pathways have been best described in Arabidopsis, which currently offers a detailed conceptual framework serves comparison other species. Rice, focus this review, also possesses photoperiodic pathway, but 150 million years divergent evolution very different environments diversified its molecular architecture.

The timing of floral transition is determined by both endogenous molecular pathways and external environmental conditions. Among these conditions, photoperiod acts as a cue to regulate the flowering in response seasonal changes. Additionally, it has become clear that various factors also control transition. Environmental factor either positive or negative signal modulate flowering, thereby establishing optimal time maximize reproductive success plants. This review aims summarize effects such photoperiod, light intensity, temperature changes, vernalization, drought, salinity on regulation plants, well further explain mechanisms link internal pathway.

Abstract How does a plant detect the changing seasons and make important developmental decisions accordingly? do they incorporate daylength information into their routine physiological processes? Photoperiodism, or capacity to measure daylength, is crucial aspect of development that helps plants determine best time year vital decisions, such as flowering. The protein CONSTANS (CO) constitutes central regulator this sensing mechanism, not only activating florigen production in leaves but also participating many aspects which seasonality important. Recent discoveries place CO center gene network can length day confer seasonal input physiology senescence, seed size, circadian rhythms. In review, we discuss importance structure, function, evolutionary mechanisms embryophytes have developed annual physiology.

Time to flowering (vegetative reproductive phase) is tightly regulated by endogenous factors and environmental cues ensure proper successful reproduction. How coordinate with signals regulate time in plants unclear. Transcription ETHYLENE INSENSITIVE 3 (EIN3) its homolog EIN3 LIKE 1 (EIL1) are the core downstream regulators ethylene signal transduction, their null mutants exhibit late Arabidopsis (Arabidopsis thaliana); however, precise mechanism of floral transition remains unknown. Here, we reveal that FLOWERING LOCUS D (FLD), encoding a histone demethylase acting autonomous pathway transition, physically associates EIL1. Loss EIL1 upregulated transcriptional expression repressor C (FLC) homologs Arabidopsis, ethylene-insensitive displayed inhibited an FLC-dependent manner.
