Chilling stress is a major environmental factor that significantly reduces crop production. To adapt to chilling stress, plants activate series of cellular responses and accumulate an array metabolites, particularly proline. Here, we report the transcription SlWRKY51 increases proline contents in tomato (Solanum lycopersicum) under stress. expression induced Knockdown or knockout led chilling-sensitive phenotypes, with lower photosynthetic capacity more reactive oxygen species (ROS) accumulation than wild type (WT). The were reduced knockdown lines perhaps explaining phenotypes these lines. D-1-pyrroline-5-carboxylate synthetase (P5CS), which catalyses rate-limiting step biosynthesis, encoded by two closely related P5CS genes (P5CS1 P5CS2). We demonstrate directly activates P5CS1 In addition, VQ (a class plant-specific proteins containing conserved motif FxxhVQxhTG) family member SlVQ10 physically interacts enhance its activation P5CS1. Our study reveals chilling-induced enhances tolerance promoting accumulation.

Liriodendron chinense (Hemsl.) Sarg. (Magnoliales: Magnoliaceae), valued for its medicinal properties and timber as an ornamental plant, is now classified endangered species. Investigating how future climate-change scenarios might affect the potential geographic distribution of L. will provide a crucial scientific basis protection management strategies. The MaxEnt model was calibrated using ENMeval optimization package, then it coupled with ArcGIS 10.8 to forecast possible areas in China, utilizing elevation data, bioclimatic factors, human footprint environmental variables. results indicate: (1) optimal parameters were set follows: FC = LQ, RM 0.5, demonstrated high predictive accuracy minimal overfitting; (2) total suitable habitat area geographical during current period estimated at 151.55 × 104 km2, predominantly located central, eastern, southwestern regions China; (3) minimum temperature coldest month (bio6), precipitation driest (bio14), quarter (bio17), warmest (bio18), (alt), (hf) are main variables determining chinense; (4) During from 2041 2060, under carbon emission SSP126, SSP245, SSP370, shows varying degrees increase compared period. However, highest concentration scenario SSP585, decreases some extent; (5) likely move towards higher latitudes elevations due changes climate. This research provides comprehensive analysis impacts climate change on chinense, offering valuable information climatic conditions.

Abstract As sessile organisms, plants are inevitably threatened by various abiotic stresses. Abiotic stresses seriously affect plant growth and development crop yield. Plants have evolved complex regulatory networks to resist that occur during their life cycle. The hormone abscisic acid (ABA) is accumulated under osmotic stress conditions such as drought, salt, others. ABA signaling pathway plays a key role in response stresses, which ABA‐responsive element binding factors (ABFs) play crucial the whole process. ABFs class of basic leucine zipper proteins (bZIPs) specifically recognize elements belong subfamily bZIP family. discoveries ABFs‐mediated tolerance multiple including salinity, cold, heat highlighted discussed this review. aim review further analyze mechanisms regulation mediated lay foundation for breeding superior stress‐resistant varieties.

Alfalfa species Medicago sativa L. (MS) and falcata (MF), globally prominent perennial leguminous forages, hold substantial economic value. However, our comprehension of the molecular mechanisms governing their resistance to cold stress remains limited. To address this knowledge gap, we scrutinized compared MS MF cold-stress responses at level following 24 h 120 low-temperature exposure (4 °C). Our study revealed that had superior physiological resilience with MS, its morphology was healthier under stress, malondialdehyde content superoxide dismutase activity increased, first, then decreased, while soluble sugar continued accumulate. Transcriptome analysis showed after exposure, there were different gene-expression patterns between MF, including 1274 2983 genes continuously up-regulated, respectively, a total 923 included, star cold-resistant such as ICE1 SIP1. Gene ontology (GO) enrichment Kyoto Encyclopedia Genes Genomes (KEGG) pathway analyses numerous inter-species differences in sustained responses. Notably, MS-exclusive included single transcription factor (TF) gene several associated DNA repair-related pathway, whereas MF-exclusive comprised nine TF 14 pathways. Both exhibited high-level expression encoding TFs belonging AP2-EREBP, ARR-B, bHLH families, indicating potential roles sustaining alfalfa-related species. These findings provide insights into which could inform breeding programs aimed enhancing alfalfa cultivars.

Climate change has emerged as a crucial global issue that significantly threatens the survival of plants. In particular, low temperature (LT) is one critical environmental factors influence plant morphological, physiological, and biochemical changes during both vegetative reproductive growth stages. LT, including abrupt drops in temperature, well winter conditions, can cause detrimental effects on development tomato plants, ranging from sowing, transplanting, truss appearance, flowering, fertilization, fruit ripening, yields. Therefore, it imperative to understand comprehensive mechanisms underlying adaptation acclimation plants morphological molecular levels. this review, we discuss previous current knowledge changes, which contain parameters involving leaf length (LL), height (PH) stem diameter (SD), set (FS), ripening yield (FY), photosynthetic parameters, cell membrane stability, osmolytes, ROS homeostasis via antioxidants scavenging systems LT stress Moreover, highlight recent advances understanding mechanisms, perception, signaling transduction, gene regulation, epigenetic regulation. The response provides solid basis develop LT-resistant varieties for sustainable production under ever-changing fluctuations.

Ethylene is a signalling factor that plays key role in the response of plants to abiotic stresses, such as cold stress. Recent studies have shown exogenous application 1-aminocyclopropane-1-carboxylate (ACC), an ethylene promoter, affects plant tolerance. The cold-responsive specific gene DREB crucial enhancing tolerance by activating several (COR) genes. However, how biosynthesis pathway regulates this thermophilic has yet be fully elucidated. In study, Plumbago indica L. was used example. Physiological experiments and transcriptomic analyses revealed stress treatment induced synthesis endogenous ACC regulated activator PiERF1, also activated PiDREB1A. Spray ACC-induced upregulation PiERF1 reduced P. decreased expression level PiDREB1A gene. These results indicate directly downstream initiates DREB‒COR regulate tolerance, resulting negative regulation plants.
