Abstract:

A total of 17 endophytic actinomycete strains were obtained from 6 medicinal plants of Mizoram, Northeast, India. 16S rRNA results showed 13 (73.3%) of the isolates belonged to the genus Streptomyces, 2 (13.3%) were Nocardiopsis, 1 (6.6%) were Tsukamurella tyrosinosolvens and 1 (6.6%) Actinobacteria bacterium. The highest number of endophytic actinomycetes was isolated from root tissue of Mikania micrantha Kunth. WI. (29.4%) followed by stem of Mikania micrantha Kunth. WI. and rhizome ofCostusspeciosus (J. Konig). Eight endophytic Streptomyces showed activity against two major phytopathogenic fungi: Fusarium oxysporum f. sp. ciceri (MTCC-2791) and Fusarium proliferatum (MTCC-286). Six isolates showed solubilisation of inorganic phosphorous. All the isolates showed abilities to produce indole-3-acetic acid (IAA) and ammonia. These results clearly suggested that endophytic actinomycetes were alternative source as bioinoculents for plant growth promotion or as well as biocontrol agent for sustainable agricultural developments.
