摘　　要：柑橘是世界第一大水果,其种植面积946.7万公顷,年产约1.5亿吨,居世界水果产量第一位(国家统计局2020年数据)。湖北省柑橘栽培面积在全国排第六位,产量第三位,占全省水果总产量的60%以上,是我国柑橘产业主优势区域布局中的重要产区(唯恒农业数据)。柑橘在全世界范围内具有长期的选育和栽培历史,近年来随着全球柑橘种质和苗木的频繁交流,促进了柑橘病害的起源和扩散。Citrus is one of the most important fruits in China and is cultivated extensively in southern China.Fusarium fujikuroi has been reported to cause diseases on various plants excluding citrus worldwide.In this study,by using tissue separation method,23 Fusarium-like isolates were isolated from diseased citrus leaves from eight different citrus planting areas in Hubei province.STJ-4 was selected as a representative isolate for further analysis,which included analyses of morphological characteristics,partial sequences of ITS,EF-1α,and RPB1 genes,phylogenetic trees based on the three genes and pathogenicity.Results showed that the STJ-4 isolate was identified as F.fujikuroi,which is the first report of F.fujikuroi causing leaf rot disease on citrus.Our study is important for developing the prevention strategies against F.fujikuroi in the future.
