Huanglongbing (HLB) constitutes the most destructive disease of citrus worldwide, yet no established efficient management measures exist for it. Brassinosteroids, a family of plant steroidal compounds, are essential for plant growth, development and stress tolerance. As a possible control strategy for HLB, epibrassinolide was applied to as a foliar spray to citrus plants infected with the causal agent of HLB, 'Candidatus Liberibacter asiaticus'. The bacterial titers were reduced after treatment with epibrassinolide under both greenhouse and field conditions but were stronger in the greenhouse. Known defense genes were induced in leaves by epibrassinolide. With the SuperSAGE technology combined with next generation sequencing, induction of genes known to be associated with defense response to bacteria and hormone transduction pathways were identified. The results demonstrate that epibrassinolide may provide a useful tool for the management of HLB.
黄龙病是全球最具毁灭性的柑橘病害，但目前尚无成熟有效的管理措施。油菜素甾醇是一类植物甾醇化合物，对植物生长、发育和胁迫耐受性至关重要。作为黄龙病的一种可能防治策略，将表油菜素内酯作为叶面喷雾剂施用于感染黄龙病病原体“亚洲韧皮杆菌”的柑橘植株。在温室和田间条件下，用表油菜素内酯处理后细菌滴度均降低，但在温室中效果更强。表油菜素内酯可诱导叶片中已知的防御基因。结合超级SAGE技术和下一代测序，鉴定出了已知与细菌防御反应和激素转导途径相关的基因诱导情况。结果表明，表油菜素内酯可能为黄龙病的管理提供一种有用的工具。
