可持续农业需要开发环境安全的方法来保护植物免受病原体的侵害。在这些方法中，生物防治剂的应用已被有效地用于最大限度地减少疾病的发展。本文就hrp（hypersensitive response and pathogenicity）基因突变菌株对植物主要病害的生物防治机制进行综述。这些突变体能够穿透植物组织并刺激植物的基础抗性。新的保护机制，涉及植物激素脱落酸似乎在拟南芥青枯病诱导的生物防治中发挥关键作用。充分了解这些机制，并将研究扩展到其他病理系统，仍然需要评估其在疾病保护中的重要性。
Sustainable agriculture necessitates development of environmentally safe methods to protect plants against pathogens. Among these methods, application of biocontrol agents has been efficiently used to minimize disease development. Here we review current understanding of mechanisms involved in biocontrol of the main Gramphytopathogenic bacteria-induced diseases by plant inoculation with strains mutated in hrp (hypersensitive response and pathogenicity) genes. These mutants are able to penetrate plant tissues and to stimulate basal resistance of plants. Novel protection mechanisms involving the phytohormone abscisic acid appear to play key roles in the biocontrol of wilt disease induced by Ralstonia solanacearum in Arabidopsis thaliana. Fully understanding these mechanisms and extending the studies to other pathosystems are still required to evaluate their importance in disease protection.
