SUMMARY Cold and saline‐alkali stress are frequently encountered by plants, they often occur simultaneously in soils at mid to high latitudes, constraining forage crop distribution production. However, the mechanisms which crops respond combination of cold remain unknown. Alfalfa ( Medicago sativa L.) is one most essential grasses world. In this study, we analyzed complex response two alfalfa species (Zhaodong [ZD] Blue Moon [BM]) combined using multi‐omics. The results revealed that ZD had a greater ability tolerate than BM. tricarboxylic acid cycles varieties responded positively stress, with accumulating more sugars, amino acids, jasmonic acid. gene expression flavonoid content biosynthesis pathway were significantly different between varieties. Weighted co‐expression network analysis based on RNA‐Seq data suggested MsMYB12 may regulating pathway. can directly bind promoter MsFLS13 promote its expression. Moreover, overexpression enhance flavonol accumulation antioxidant capacity, improve tolerance. These findings provide new insights into improving resistance showing flavonoids for plant stresses, theoretical guidance future breeding programs.

Walnuts are among the globally significant woody food and oil tree species. At high latitudes, they frequently experience late-frost damage, inducing low-temperature stress, which significantly affects walnut seedlings. The aim of this study was to investigate physiological biochemical alterations in seedlings under (LT) stress along with its underlying molecular mechanisms. Physiological indices were determined, transcriptome miRNA sequenced by sampling leaves (0 h, 6 12 24 48 h) two-month-old live walnuts treated a low temperature 4 °C. results indicated that LT induced an increase electrical conductivity malondialdehyde content while simultaneously causing reduction Fv/Fm. From comparison between control groups, total 12,566 differentially expressed genes (DEGs) identified, consisting 6829 up-regulated 5737 down-regulated genes. Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) enrichment analyses revealed DEGs primarily enriched polysaccharide metabolic processes, responses abscisic acid phenylpropanoid biosynthesis pathways. Furthermore, database identified 1052 miRNAs response walnuts; these found target 7043 predicted Through integration analysis data, 244 differential identified. Following GO KEGG genes, we regulate pathways involved starch sucrose metabolism, glyoxylate dicarboxylate glycerophospholipid biosynthesis, as well phenylalanine, tyrosine, tryptophan stress. Additionally, conducted in-depth associations microRNAs (DEMs) within metabolism pathway. Real-time fluorescent quantitative PCR (qRT-PCR) validation expression patterns subset confirmed accuracy data. This unveils potential mechanisms walnut’s providing valuable genetic resources for future research on cold tolerance damage.

The depletion of the ozone layer has resulted in elevated ultraviolet-B (UV-B) radiation levels, posing a significant risk to terrestrial plant growth. Rhododendron chrysanthum Pall. (R. chrysanthum), adapted high-altitude and high-irradiation environments, developed unique adaptive mechanisms. This study exposed R. UV-B for two days, with an 8 h daily treatment, utilizing metabolomic transcriptomic analyses explore role WRKY transcription factors plant’s stress response their regulation flavonoid synthesis. decrease rETR Ik increase 1-qP. These chlorophyll fluorescence parameters indicate that impaired photosynthesis chrysanthum. Faced detrimental impact radiation, is capable mitigating its effects by modulating biosynthetic pathways adapt positively stress. revealed changes expression 113 flavonoid-related metabolites 42 associated genes, showing correlation these alterations. can influence key enzyme genes metabolic pathway, thereby affecting metabolite production. A theoretical reference investigating physiology provided this work, which also offers insights into responses alpine plants under adverse conditions.

Common bean (Phaseolus vulgaris L.) is a thermophilic crop, and exposure to cold stress can significantly impact their yield quality. To elucidate the of on cold-tolerant 'Wei Yuan' (WY) cold-sensitive 'Bai Bu Lao' (BBL) common bean, mechanism tolerance was studied by physiological biochemical multi-omics analysis. In this study, lower relative conductivity higher malondialdehyde content after endowed 'WY' seedlings with tolerance. A total 11,837 differentially expressed genes (DEGs) 923 differential metabolites (DEMs) were identified transcriptome metabolomics Joint analysis showed that under stress, DEGs DEMs in beans are extensively engaged sugar, amino acid isoflavonoid biosynthesis, flavone flavonol plant hormone signal translation, especially related isoflavone biosynthesis. addition, it also found bHLH MYB family transcription factors may be involved transduction bean. The above results will provide theoretical basis for help screening resources beans. Not applicable.

Low temperature is a primary abiotic stress that significantly affects plant growth and development in the cool regions of Northeast China. It limiting factor global apple industry. Numerous studies have investigated alterations transcriptional metabolism under low-temperature various plants. However, research on role dormancy regulating differences cold tolerance among varieties limited. Therefore, this study conducted comprehensive analysis physiological biochemical indices, transcriptome, metabolome cold-tolerant variety 'Hanfu' (HF) cold-sensitive 'Naganofuji 2′ (CF) during endodormancy ecodormancy. Under treatment, cross-section 1-year-old branch CF exhibited more severe browning than HF did, relative electrolyte leakage value was higher HF. Transcriptomics metabolomics revealed key pathways apples response to stress. Functional enrichment showed hormone signal transduction amino acid metabolism-related were enriched ecodormancy, these considered an important way for respond freezing injury. The galactose pathway only endodormancy, while membrane lipid A gene co-expression network constructed using weighted correlation analysis, six modules with biological significance selected from network. Among them, genes encoding transcription factors such as DREB1C/CBF2, JUB1, CCCH, VIP1 are hub different modules, which can be used candidate explore regulation Overall, findings help elucidate molecular mechanism underlying freeze-tolerance provide novel insights into regulatory involved dormancy.

Abstract Cold stress profoundly affects the growth, development, and productivity of horticultural crops. Among diverse strategies plants employ to mitigate adverse effects cold stress, flavonoids have emerged as pivotal components in enhancing plant resilience. This review was written systematically highlight critical role tolerance, aiming address increasing need for sustainable practices under climate stress. We provide a comprehensive overview tolerance crops, emphasizing their biosynthesis pathways, molecular mechanisms, regulatory aspects conditions. discuss how act antioxidants, scavenging reactive oxygen species (ROS) generated during they regulate gene expression by modulating stress-responsive genes pathways.
