Abstract

Endophytic bacteriareside with in plant hosts without causing disease. In our study, we isolates four endophytic bacteria from explants (root,stem, petiole, and leaf) of Aloe Barbadensis, Adhatoda vasica, Phyllanthus amarus and Calotrophis gigantea.Entophytic bacteria such as Azotobacter,Xanthomonas and Pseudomonas could be identified from explants through various biochemical test. Endophytic bacteria were beneficial to the plant growth and it can be proved that inoculate to Mustard plant which was showed good growth promoting effect. The endophytes contributes substances that possess biocontrol activity against Curvularia sp., and Alternaria sp.,.Thus in ourstudy,we focus on the growth promoting effect of endophytic bacteria in mustard plant and biocontrol activity against fungal pathogens.
