Plant bacterial endophytes as a potent source of plant growth promoters and other bioactive compounds: A Review

摘要

The global climate is drastically changing. Climate change factors such as enhanced CO2 levels, increased temperature and drought affect all plant-microorganism interactions. Plants are associated with a variety of microorganisms which can occur as epiphytes or endophytes. Endophytes are present inside the host plants whereas epiphytes are present on the surface of host plants. Endophytes are known to be reservoirs of novel bioactive compounds such as phenolic acids, alkaloids, terpenoids and steroids that has properties such as anti-microbial, anticancer and anti-insect. They are also known to enhance the growth of host plants and provide resistance to several diseases, biotic and abiotic stresses. This review aims to discuss the various functionsand behavior of endophytes and the effect of climatic changes on their activities.
