Plant–associated beneficial Burkholderia

Abstract:

Burkholderia spp. is a class of Gram-negative bacteria with a wide geographical and niche distribution. In recent years, with the increasing research on plant associated Burkholderia, more and more evidences suggest that Burkholderia is an important plant-associated beneficial microorganism. Burkholderia could promote plant growth through biological nitrogen fixation, phosphorus solubilizing, to increase nitrogen and phosphorus absorption, production of phytohormones like IAA and antifungal metabolites to inhibit the growth of phytopathogenic microorganisms. All of these make Burkholderia with great application potential in promoting plant growth and health. This article reviews the research progresses of the plant-associated beneficial Burkholderia and discusses its application prospects in agriculture.
