Ten newly isolated endophytic fungi from Phyllathus niruri Linn. were identified as Fusarium oxysporum. These isolates were screened out for their productivity of indole acetic acid (IAA) by the salkowski's method. Out of these isolates, two isolates showed high amount of indole acetic acid production, which were FO9 and FO10 with concentration of 23.52 μg/ml and 5.95 μg/ml, respectively.

The present study aims to identify the diverse endophytic fungi residing in the roots of Dendrobium moniliforme and their role in plant growth and development. Nine endophytic fungi were isolated from the root sections and characterized by molecular technique. Quantification of the indole acetic acid (IAA) compound by these endophytes was done. Further, Chemical profiling of R11 and R13 fungi was done by Gas Chromatography-Mass Spectroscopy (GC-MS). Asymbiotic seed derived protocorms of Rhynchostylis retusa was used for the plant growth assay to investigate the growth promoting activities of the fungal elicitor prepared from the isolated fungi from D. moniliforme. Among the isolated fungi, the relative dominant fungus was Fusarium sp. The R13 and R6 fungi were identified only at the genus level which concludes the fungi are of new species or strain. The indole acetic acid production was relatively higher in R10. Bioactive compound diversity was observed in the organic extract of R11 and R6. The presence of phenolic compound and essential oil suggest their contribution for the antimicrobial and antioxidant properties to their host plant, D. moniliforme. The plant growth assay result concluded, the fungal elicitor prepared from R10, Colletotrichum alatae was the best among all other for the plant growth activities.

ABSTRACT In a plant-endophyte relationship, substances secreted by microorganisms can help the plant to defend itself against pathogens and also to promote an increase in biomass. This study aimed to biochemically characterize endophytic fungi from Bambusa oldhamii Munro, aiming at future studies on plant growth promotion, as well as on resistance induction. The following fungal isolates from B. oldhamii were used: 29 (Acrocalymma sp.); 122 (Botryobambusa fusicoccum); 711 (Phoma sp.); and 712 (Phoma sp.). Biochemical characterization was performed, analyzing the production of indole-acetic acid, chitinases and glucanases, as well as the presence or absence of polyphenol oxidases and phosphate solubilization activity in vitro. The isolate 29 produced larger amounts of indole-acetic acid and chitinases, yielding 31.55 mg mL-1 after 96 h and 2.59 U mL-1 after 120 h, respectively. The isolate 122 produced an increased amount of glucanases, yielding 2.65 U mL-1 after 72 h. The isolates 29, 711 and 712 produced polyphenol oxidases. The isolate 711 showed phosphate solubilization activity in vitro. These results indicate that the isolates under study show a potential for inducing resistance in plants and for future studies on the increase of plant biomass.

Root And Shoot Growth

Indole acetic acid is a natural phytohormone which influence the root and shoot growth of the plants. Six (GM1-GM6) endosymbiotic bacteria are isolated from Gracilaria corticata and screened for the production of IAA out of six, three bacterial strains GM3, GM5 and GM6 produced significant amount of IAA 102.4 µg/ml 89.40 µg/ml 109.43 µg/ml respectively. Presence of IAA in culture filtrate of the above strains is further analyzed and confirmed by TLC. As these bacterial strains, able to tolerate the high salinity these can be effectively used as PGR to increase the crop yield in saline soils.
