摘　　要：伯克霍尔德氏菌(Burkholderia)是一类革兰氏阴性细菌,随着与植物相关的伯克霍尔德氏菌的研究不断增加,越来越多的结果表明,该属细菌可作为一类重要的生防有益微生物。本文综述了伯克霍尔德氏菌的分类和生理生化特征;在植物病害生物防治上的应用及作用机制,主要包括嗜铁素产生及生存空间竞争,拮抗作用中抗生素产生,诱导植物产生抗病性等;还综述了伯克霍尔德氏菌的固氮、解磷、植物激素产生等促生长特性。本论文为伯克霍尔德氏菌的生防机制研究和应用开发提供了理论依据。Burkholderia is a group of Gram-negative bacteria.As plant-related research on Burkholderia incrementally came out,more and more evidence indicated that this bacterial genus could serve as an important beneficial microorganism in biocontrol.This paper provides an overview of the classification and physiological and biochemical characteristics of Burkholderia;application and mechanisms of Burkholderia in plant disease biocontrol,including siderophore production and spatial competition for survival,antibiotic production in antagonistic action,and induction of plant disease resistance;moreover,it reviewed the growth-promoting traits of Burkholderia,such as nitrogen fixation,phosphate solubilization,and production of plant hormones.This paper contributes a theoretical foundation to the research and application development of Burkholderia biocontrol mechanisms.
