- Researchers at IASST Guwahati, have found significant plant-growth-promoting and antifungal activities of endophyticactino bacteria associated with Tea plant and related genera, Eurya to find potent plant growth-promoting strains.
About:
- Researchers isolated 46 endophyticactino bacteria found in diverse environments
- Most of the endophyticactino bacteria isolates having antifungal activity showed presence of chitinase, NRPS (Nonribosomal peptides synthetase) or PKS-1 (Polyketide Synthase) gene, suggesting the presence of mechanisms to inhibit the growth of pathogenic plant fungi.
- Application of endophytic Actinobacteria could reduce chemical fertilizers & fungicides in Tea plantation.
