类拟盘多毛孢真菌(Pestalotiopsis-like fungi)是危害蓝莓的一类重要病原菌。实验室前期对比发现有8株分离自蓝莓病样的类拟盘多毛孢菌单独聚成一支,并且与危害蓝莓的类拟盘多毛孢已知种相互区分,表明这8株菌有可能是危害蓝莓的新纪录种或新种。为明确这8株菌的种群分类地位,本研究对供试菌株进行形态学鉴定及系统发育分析,结果表明它们隶属于污斑新拟盘多毛孢Neopestalotiopsis foedans,这是该菌危害蓝莓在国内外的首次报道。在此基础上,进一步研究了该新纪录种不同菌株对辽宁省5个蓝莓主栽品种的致病能力,结果表明这8株菌的致病力具有明显分化,不同蓝莓品种均对强致病菌株较敏感,生产中应当加以重视。 |

Pestalotiopsis-like fungi are an important class of pathogens on blueberry.Based on comparison analysis with reported Pestalotiopsis-like fungi on blueberry,8 Pestalotiopsis-like isolates from blueberry were distinguished from those reported species and classified together in a single branch,which suggest that these isolates may be as a new record species or a novel species.Morphological and molecular phylogenetic methods were used to classify the 8 isolates,and the results suggested that they were Neopestalotiopsis foedans,which was the first report of N.foedans causing blueberry disease in the world.Further evidences showed that these 8 isolates had different virulence on five main blueberry cultivars in Liaoning Province.However,almost all tested cultivars were sensitive to the isolates with strong virulence,which should be considered in practice. |
