摘要 从江苏盐城地区种植的蓖麻上采集分离到1株编号为YDJ08的病原菌。通过形态学观察和分子生物学研究对其进行鉴定,结果显示:在PDA培养基上,真菌菌落形态为圆形,菌落初期为白色,后转变为黑色,分生孢子呈梭形、薄壁、外壁光滑、无色;病原菌在蓖麻植株上接种后表现为木质部变黑;ITS和β-tubulin序列分析表明该菌株与Gen Bank中葡萄座腔菌(Botryosphaeria dothidea)的序列相似性分别高达100%和99%。综合形态学和序列比对分析推断该菌株为葡萄座腔菌。这是首次报道侵染蓖麻的葡萄座腔菌,该菌株的ITS和β-tubulin序列的Gen Bank登录号为KJ530706、KJ530707。
