Endophytic Bacteria as a Modern Tool for Sustainable Crop Management Under Stress

Part of the Soil Biology book series (SOILBIOL, volume 55)


Plant growth and development under both biotic and abiotic stress is enabled by the bacteria residing in plants, especially in the roots. Of many isolated endophytic bacteria, two isolates, Pseudomonas aeruginosa and Pseudomonas pseudoalcaligenes, on the basis of the presence of the nifH gene and growth elevation potential were selected as a tool to develop tolerance in crops under stress. Plants inoculated with such bacteria have better nutrient status under stress. Abiotic stress, especially salinity, causes consequences in altered protein profiling, production of low molecular weight chaperones, as well as production of nontoxic osmo-protectants in plants to overcome stress. Isolated endophytes also induce differential gene expression of β-1,3-glucanase and RAB18, which has been observed during RNA profiling. Such plants acquire better ability to survive under stressful environments. These findings suggest that the ecologically safe endophytic bacteria can be a modest and economic tool for regulating several plant metabolites and opposing stress to enhance crop production by assisting stress management in crop plants. Use of such beneficial bacteria in diverse agronomic systems to develop plants broadly resistant under both stressed and normal states is a current need.
