Abstract
Naturally, all plants harbor a diversity of endophytes and can produce a variety of compounds which positively affect the growth of their host plant. Endophytes can contribute in providing plant supplements, conflicting with pathogens, or directly influencing the growth and development of plants through synthesis of phytohormones. The present study aimed to explore the diversity of endophytic fungi from different parts of the three healthy halophytic plants i.e., Solanum surattense Burm. f., Chenopodium album L. and Zizyphus nummularia (Burm. f). As sa result, twenty-two endophytic fungi mostly belonging to ascomycetes were isolated from 92 samples with an overall colonization frequency of 23.02%. The endophytic fungi showed a relatively high percentage of colonization frequency (25%) in roots as compared to other parts. The isolated fungal strains were tested for salt tolerance and for their ability to produce plant hormone indole-3-acetic acid (IAA). Out of 12 different strains, five strains have salt tolerance potential and eight strains have shown to produce IAA in culture media. Further the isolated strains were also screened for their growth promoting activities such as 1-aminocyclopropane1-carboxylate deaminase, flavonoids, phenol, solubilize phosphate and to produce siderophores.
