Exploring Endophytic Bacteria from spp. and Beneficial Traits on Pea Plants.

Endophytic microorganisms represent promising solutions to environmental challenges inherent in conventional agricultural practices. This study concentrates on the identification of endophytic bacteria isolated from the root, stem, and leaf tissues of four plant species. Sixty-one strains were isolated and sequenced by 16S rDNA. Sequencing revealed diverse genera among the isolated bacteria from different species, including , , , and . AR11 and VR24 obtained from the roots of and demonstrated significant inhibition on c.f. mycelial growth. In addition, AR11, AR32, and CR25 exhibited significant activity in phosphatase solubilization, nitrogen fixation, and indole production, highlighting their potential to facilitate plant growth. A comparative analysis of species showed that root isolates from , , and have beneficial properties for inhibiting pathogen growth and enhancing plant growth. AR11 with 100% similarity to , could be considered a promising candidate for further investigation as microbial biofertilizers. This finding highlights their potential as environmentally friendly alternatives to chemical pesticides, thereby contributing to sustainable crop protection practices.
