研究领域
海洋微生物可移动遗传元件的功能及转移机制研究。
代表性工作简介
主要研究海洋微生物中可移动遗传元件的生理生态功能和水平转移机制,解析可移动遗传元件调控海洋微生物环境适应性及介导珊瑚共生微生物互作的机理。代表性成果主要包括:前期建立了基于同源重组和sacB基因反筛选的海洋细菌遗传操作体系(Microbial Cell Factories, 2015),可对弧菌、假交替单胞菌等海洋细菌进行高效的基因敲除;近期又构建了基于 CRISPR/Cas9技术的遗传操作手段(Journal of Antimicrob Chemother, 2019),不仅可用于海洋细菌的基因编辑,还可以实现质粒、原噬菌体等水平转移元件的精确消除。两种遗传操作体系互为补充,为开展海洋细菌分子水平研究工作提供了重要技术支持;发掘了多个调控生物膜的可移动元件,阐明了其调控生物膜形成的机理和其在不同种属细菌间水平转移的机制(Environmental Microbiology,2017),应用于珊瑚益生菌剂的开发;发现广泛分布在接合转移型质粒上的一大类毒素/抗毒素系统(Toxin/Antitoxin System, TA)的新功能,质粒上的TA系统一直被认为是通过“分离后致死效应”(Post-segregational killing, PSK)维持质粒的稳定性或增强其竞争力,实验首次证实质粒上TA可以直接调控细菌质粒的复制,是该领域有别于“PSK”理论的一项重要发现,具有重要创新性(PNAS,2021)。
