Abstract Recently, there has been a worldwide call to explore nature-friendly compounds, which could enhance plant growth and substitute for chemically synthesized products. Endophytes are group of microorganisms that lives in the plants algae symbiotically. In this research, endophytes were isolated from leaves halophyte, Limonium axillare . A total 280 bacterial isolates obtained L. Strains displaying similarities terms morphology biochemical reactions categorized into 48 groups. One representative each was identified subjected enzymatic growth-promoting tests. Forty-eight using sequence similarity-based method based on 16S rDNA gene. The strains two genera: Bacillus Staphylococcus Our investigation uncovered 44 genus, representing 10 different species, including sp., B. pseudomycoides , cereus paramycoides velezensis subtilis thuringiensis wiedmannii anthracis bacterium Furthermore, we observed only 4 belonged encompassing 3 distinct species: S. succinus saprophyticus bacteria screened extracellular enzymes, promoting traits, antifungal activity, salinity tolerance. From previous screening, diverse responses obtained. Most secreted at least one hydrolysis enzymes (protease, lipase amylase). (93.8%) showed phosphate solubilization activity. (33.3%) produce (IAA).

Cold stress (CS) affects the survivability, geographical distribution, and yield stability of crops. Suitable management agronomic practices can minimize crop losses associated with cooler environments. However, alone can't support plants adequately to withstand harsh cold. Therefore, exploring cold stress-responsive factors such as genetic, epigenetic, physiological, cellular is crucial. This report discusses on effect, signal perception, transduction, gene expression, molecular phenomena in plants. Three acclimation response pathways: Ca2+ mediated ICE1- CBF/ DREB1, hormonal, reactive oxygen species (ROS), are elucidated. Also, this summarizes latest research work genetics genomics forage from perspectives tolerance improvement. In several instances, our hypotheses have been supported by a recent output genetic analysis experiment alfalfa (Medicago sativa L.) tolerance.
