| contents | <p>Bacterial endophytes are non-pathogenic microorganisms internally associated with plants and are known to play a vital role in promoting plant growth and resistance to biotic and abiotic stress conditions. They are even capable of eliminating plant pathogens. Abiotic stresses, particularly salinity problems, heavy metal toxicity, low pH, and accumulation of xenobiotics in the soil due to harmful pesticides and fertilizers, are affecting plant health drastically. They constitute a significant threat to the agriculture sector in crop production and ecosystems' stability. Endophytic bacteria may hence be utilized as a substitute to lessen the use of toxic chemicals and pesticides. They can be used as a biological agent in plant growth promotion, including managing the global environment. Rice is an important food crop yet it is highly prone to damage due to abiotic stress. This report aimed to investigate the role of the endophytic microbes of rice seeds in tolerating various abiotic stress levels. Seven bacterial strains were isolated in this study, and their tolerance level was checked against different abiotic factors. As observed from the experiments the bacterial strain RS07 has shown the highest salt stress and temperature tolerance while the bacterial strain RS06 showed the highest pH and xenobiotics tolerance as inferred from the results thus making them the most potential endophytic bacteria. These results propose that the isolated bacteria can eventually be used to boost plant growth, combat extreme climatic conditions, harsh environment and benefit host plant to fight against fungal pathogens thereby creating a sustainable agriculture.</p> |
