摘要
本研究采用组织分离法从健康油茶叶分离获得70个间座壳属Diaporthe真菌菌株,根据形态学特征和5个片段序列(ITS、TEF、TUB、CAL、HIS)的系统发育分析,将8个代表性菌株鉴定为6个种,包括核桃间座壳D.biguttulata、榆树间座壳D.eres、香港间座壳D.hongkongensis、梭状间座壳D.fusicola及2个新种,即祁门间座壳D.qimenensis sp.nov.和肾形间座壳D.reniformis sp.nov.。2个新种均未观察到β型分生孢子,其中肾形间座壳产生明显的肾形分生孢子。
Seventy isolates of Diporthe fungi from healthy Camellia oleifera leaves were obtained by using tissue isolation method.Based on morphological characteristics and phylogenetic analysis of five fragment sequences(ITS,TEF,TUB,CAL,HIS),eight representative isolates were identified as six species,D.biguttulata,D.eres,D.hongkongensis,D.fusicola,D.qimenensis sp.nov.and D.reniformis sp.nov.β-Type conidia were not observed in the two new species.D.reniformis produces distinct reniform conidia.
