摘要

茶油树（Camelliaoleifera Abel.）是一种重要的食用油木本植物，在中国南方的种植面积超过 380 万公顷。Diaporthe 菌种作为植物病原菌、内生菌和酵母菌栖息在多种植物寄主上。在此，我们在海南省进行了广泛的实地调查，以鉴定与茶油叶斑病相关的 Diaporthe 物种并确定其特征。结果，从有症状的油茶叶中获得了 8 个 Diaporthe 分离物。根据形态学和部分 ITS、cal、his3、tef1 和 tub2 基因区域的系统发育分析，对这些分离物进行了研究。本文提出并描述了两个新的 Diaporthe 物种（D.hainanensis 和 D.pseudofoliicola）。

Two new species of Diaporthe (Diaporthaceae, Diaporthales) associated with Camelliaoleifera leaf spot disease in Hainan Province, China.

Tea-oil tree (Camelliaoleifera Abel.) is an important edible oil woody plant with a planting area over 3,800,000 hectares in southern China. Species of Diaporthe inhabit a wide range of plant hosts as plant pathogens, endophytes and saprobes. Here, we conducted an extensive field survey in Hainan Province to identify and characterise Diaporthe species associated with tea-oil leaf spots. As a result, eight isolates of Diaporthe were obtained from symptomatic C.oleifera leaves. These isolates were studied, based on morphological and phylogenetic analyses of partial ITS, cal, his3, tef1 and tub2 gene regions. Two new Diaporthe species (D.hainanensis and D.pseudofoliicola) were proposed and described herein.
