Abstract

Huanglongbing (HLB) is a severe citrus disease that results in significant yield loss, caused by the phloem-dwelling pathogen Liberibacter asiaticus (Las). Currently, antibiotics including penicillin, chloromycetin, and streptomycin are extensively utilized for the control of HLB in citrus production. However, various issues have emerged following the application of antibiotics, including the development of resistant microorganisms in soil and the accumulation of antibiotic residues in fruits. Consequently, there is an urgent need for alternative environmentally friendly methods for HLB control. In this study, the curative effects of strain HN11 and Arbuscular Mycorrhizal Fungi (AMF) on HLB were investigated. The HN11 strain and AMF demonstrated stable colonization within the interior of citrus roots. Moreover, HN11+AMF inoculation promoted the growth of HLB-infected citrus trees, accompanied by the decrease in Las titers, reduction in HO content, callus deposition, starch content, and ion leakage, as well as improvements in antioxidant enzyme activity indicators. The curative effects of HN11+AMF inoculation on HLB were also confirmed through field efficacy experiments. Moreover, HN11+AMF inoculation was identified to modify the composition and functions of root-soil bacterial and fungal microbial communities. These findings indicate that the use of HN11+AMF inoculation may serve as a promising control strategy for HLB management.

摘要

黄龙病(HLB)是一种严重的柑橘病害,会导致大幅减产,由韧皮部寄生病原菌亚洲韧皮杆菌(Las)引起。目前,包括青霉素、氯霉素和链霉素在内的抗生素在柑橘生产中被广泛用于防治黄龙病。然而,抗生素应用后出现了各种问题,包括土壤中抗性微生物的产生以及水果中抗生素残留的积累。因此,迫切需要替代的环保型黄龙病防治方法。在本研究中,研究了菌株HN11和丛枝菌根真菌(AMF)对黄龙病的治疗效果。HN11菌株和AMF在柑橘根内部表现出稳定的定殖。此外,接种HN11+AMF促进了感染黄龙病的柑橘树的生长,同时伴随着Las滴度的降低、HO含量的减少、愈伤组织沉积、淀粉含量和离子渗漏的减少,以及抗氧化酶活性指标的改善。通过田间药效试验也证实了接种HN11+AMF对黄龙病的治疗效果。此外,已确定接种HN11+AMF会改变根际土壤细菌和真菌微生物群落的组成和功能。这些发现表明,使用HN11+AMF接种可能是一种有前景的黄龙病管理控制策略。
