Identification of Pathogenic Fungus Causing Kiwifruit Leaf Spot in Fengxin County of Jiangxi Province
摘要
Abstract
In order to ascertain the fungal species responsible for the new kiwifruit leaf disease in Fengxin County of Jiangxi Province,a fungus was isolated from the diseased leaf samples by using the tissue isolation method.The obtained fungus was identified based on morphology and molecular biology,and its pathogenicity was tested.In total,32 fungal isolates with pathogenicity in artificially inoculation test were obtained.The cultur-al characters and conidial morphology and size of each isolate were identical, and consistent with those of Corynespora cassiicola in literature. Three isolates were randomly selected for analyzing their rDNA-ITS se-quences.The three rDNA-ITS sequences obtained were the same and identical to that of C. cassiicola. Thus,it may be concluded that the pathogen of kiwifruit leaf spot disease in Fengxin County of Jiangxi Province is Corynespora cassiicola,a species of genus Corynespora in fungi imperfect.关键词
