【摘要】：黃單胞菌屬(Xanthomonas)是一類能引起多種單子葉和雙子葉植物感病的革蘭氏陰性細菌,嚴重危害水稻、甘藍、番茄、柑橘等多種作物,其入侵和增殖依賴于三型分泌系統(tǒng)(Type III Secretion System,T3SS)和其他毒素因子。細菌非編碼小RNA能通過與靶m RNA互作,在轉(zhuǎn)錄后水平調(diào)控基因的表達,或直接與蛋白互作,影響細胞的各種生理功能。主要介紹了細菌非編碼小RNA的分類、及其對細菌蛋白調(diào)節(jié)、生長代謝、基因轉(zhuǎn)錄以及毒力調(diào)控等方面的研究進展,并重點對黃單胞菌屬細菌已鑒定的非編碼小RNA及其生物學功能進行綜述,以期為黃單胞菌引起的作物病害防控提供新的思路。
[Abstract]:Xanthomonas (Xanthomonas) is a class of Gram-negative bacteria that can cause many kinds of monocotyledonous and dicotyledonous plants to become susceptible to diseases, which seriously harm many crops, such as rice, cabbage, tomato, citrus and so on. Its invasion and proliferation depend on type 3 secretory system (Type III Secretion System,T3SS) and other toxin factors. Bacterial non-coding small RNA can regulate the expression of genes at post-transcriptional level or directly interact with proteins through interaction with target m RNA, which can affect the physiological functions of cells. In this paper, the classification of bacterial non-coding small RNA and its research progress on bacterial protein regulation, growth metabolism, gene transcription and virulence regulation were introduced. The non-coding RNA and its biological function of Xanthomonas were reviewed in order to provide a new idea for the prevention and control of crop diseases caused by Xanthomonas.
