虫瘿篮状菌和伪子座篮状菌-篮状菌属紫篮状菌组的两个我国新记录种

Talaromyces Cecidicola and T.Pseudostromaticus,Two Species of Talaromyces Section Purpurei New to China

篮状菌(Talaromyces)是土壤、空气、植物根际和叶际以及人类活动场所的常见霉菌,它们在增加土壤腐殖质、促进植物生长、矿物质吸收和抗病虫害等方面具有重要作用。系统调查我国蓝状菌物种资源是一项非常重要的基础性工作,在该项工作中我们分别从河南卫辉和内蒙古额济纳旗的土壤中分离鉴定了2株蓝状菌,即WH6-2=AS3.16006和EJ2-12=AS3.16005。通过形态学和基于β-tubulin基因和rDNA ITS1-5.8S-ITS2序列的分子种系学研究,确定它们为篮状菌属紫篮状菌组(Talaromyces section Purpurei)的我国两个新记录种,即虫瘿篮状菌(T.cecidicola)和伪子座篮状菌(T.pseudostromaticus),特在本文中报道。

Talaromyces species are common filamentous fungi inhabiting the soil,air,rhizosphere and phyllosphere of plants,which play an important role in enriching soil humus and improving the growth,mineral absorption,and disease and pest resistance of plants.It is a vital fundamental work to systematically investigate the Talaromyces species resource.During a survey of Talaromyces species in China,two strains,namely WH6-2=AS3.16006 from Henan Province and EJ2-12=AS3.16005 from Inner Mongolia,were discovered and identified as T.cecidicola and T.pseudostromaticus,respectively,according to morphological characters and phylogenetic analyses ofβ-tubulin gene and rDNA ITS1-5.8S-ITS2 sequences,thus are reported as two new record species of Talaromyces section Purpurei of China.
