Bacterial fruit blotch(BFB)is a severe seed-borne disease on melons.The typeⅡ secretion system(T2SS),one of bacterial virulence factors,may contribute to bacterial colonization and transmission.In this study,genes encoding T2 SS and the genetic organization of T2 SS clusters in Acidovorax citrulli(Ac)strain AAC00-1 were compared with those in other plant pathogen species via KEGG and STRING databases.In addition,T2 SS secretory proteins in Ac strain AAC00-1with homology to experimentally proofed T2 SS secre...

细菌性果斑病(bacterial fruit blotch,BFB)是严重威胁瓜类生产的一种毁灭性病害,在世界多个国家已将其列为重要检疫性病害,其病原菌为瓜类果斑病菌(西瓜嗜酸菌)(Acidovorax citrulli,Ac)[1]。BFB主要通过种子传播,病菌通过带菌种子传播到幼苗,引起幼苗发病,但在西甜瓜成株期病
