Alfalfa (Medicago sativa L.), a high-quality perennial legume forage, is pivotal in global animal husbandry and ecological systems. However, its growth production are threatened by various abiotic stresses, including drought, salinity, low temperatures, heavy metal toxicity. This review summarizes recent research on the molecular mechanisms underlying alfalfa’s responses to these environmental adversities. It provides theoretical foundation for enhancing stress resistance of alfalfa, offering valuable reference breeding high-quality, stress-resistant alfalfa varieties.

This study investigated the distribution of salinity and sodicity in irrigated areas Abaya Chamo. Representative water soil samples were collected from different depths (0–30 cm 30–60 cm). Sodium absorption ratio (SAR), electrical conductivity (Ec), pH, exchange sodium, magnesium, calcium, potassium cations, sodium percentage (ESP) sampled sites analyzed for classification severity analysis. The spatial analysis revealed predominant strongly saline (72%) sodic (71.1%) conditions surface layer cm), intensifying very (78.7%) (71.9%) at depth. Combined saline-sodic dominated both layers, increasing 91.2% to 97.1% deeper layer, indicating severe agricultural limitations. results show that catchments Lakes Chamo suffer content classes. Therefore, appropriate remedial measures based on should be developed achieve better reclamation, production, land sustainability.

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. Additionally, we explore application through genetic engineering breeding strategies, offering insights into practical interventions improving crop Despite significant advances, research gap remains understanding precise mechanisms which specific confer resistance, especially across different species. By addressing current knowledge gaps, proposing future directions highlighting implications horticulture, aim advance enhance

Caucasian clover (Trifolium ambiguum M.Bieb.) is a perennial legume known for its exceptional cold tolerance, commonly used in agriculture and ecosystems climates. Given the impact of climate change, enhancing adaptation crucial sustaining agricultural productivity. This study employs metabolomics, transcriptomics, Weighted Gene Co-expression Network Analysis (WGCNA) to investigate molecular mechanisms clover’s response low-temperature stress. Metabolomic analysis showed that stress triggered accumulation fatty acids, amino antioxidants, which are critical maintaining membrane stability antioxidant capacity, thus protecting plant from oxidative damage. Transcriptomic revealed significant upregulation genes involved adaptation, particularly those related defense, lipid repair, signal transduction, including ABA signaling pathway enzymes, thereby improving tolerance. WGCNA identified gene modules closely linked especially acid metabolism, repair. These function synergistically, with coordinated expression resistance. also investigated isoflavonoid biosynthesis under stress, highlighting role capacity Low-temperature induced key enzyme genes, such as Isoflavone Synthase (IFS) Isoflavone-7-O-Glucosyltransferase (IF7GT), promoting metabolite further plant’s adaptation. Overall, this offers novel insights into tolerance provides valuable theoretical support breeding cold-resistant crops

Saline-alkali stress is one of the major abiotic stresses threatening crop growth. Cotton, as a “pioneer crop” that can grow in saline and alkali lands, great significance for understanding regulatory mechanisms plant response to stresses. Upland cotton has thus become model researchers explore responses saline-alkali In this study, RNA sequencing was employed analyze tissue-specific expression root tissues TM-1 seedlings 20 min after exposure compound stress. The RNA-Seq results revealed significant molecular differences different regions treatment. A total 3939 differentially expressed genes (DEGs) were identified from pairwise comparisons between non-root tip samples, which primarily enriched pathways including hormone signal transduction, MAPK signaling, cysteine methionine metabolism. Combined with pattern investigation by quantitative real-time PCR (qRT-PCR) experiments, key gene, GhERF2 (GH_A08G1918, ethylene-responsive transcription factor 2-like), be associated tolerance. Through virus-induced gene silencing (VIGS), GhERF2-silenced plants exhibited more severe wilting phenotype under combined salt-alkali stress, along reduction leaf chlorophyll content fresh weights roots. Additionally, these showed greater cellular damage lower ability scavenge reactive oxygen species (ROS) when exposed These findings suggest may play positive role not only enhance our underlying but also provide foundation future breeding efforts aimed at improving

Abstract Alfalfa (Medicago sativa L.), a perennial legume forage, has been broadly cultivated owing to variety of favorable characteristics, including comprehensive ecological adaptability, superior nutritive value and palatability, nitrogen fixation capacity. The productivity traits alfalfa, specifically its biomass yield forage quality, are significantly influenced by series determinants, internal developmental factors external environmental cues. However, the regulatory mechanisms underlying fundamental biological problems alfalfa remain elusive. Here, we conducted review focusing on genomics advancements in gene-editing technologies, identification genes that control pivotal agronomic formation, nutritional flowering time, resistance various stresses. Moreover, molecular design roadmap for ‘ideal alfalfa’ proposed potential pangenomes, self-incompatibility mechanisms, de novo domestication, intelligent breeding strategies enhance alfalfa's yield, resilience were further discussed. This will provide information basic biology offer new insights cultivation ideal alfalfa.
