摘要:

为探明瑞香狼毒(Stellera chamaejasme)内生真菌的种类及其种属分布特点,进一步揭示瑞香狼毒内生真菌与毒性物质合成、化感作用以及抗逆性形成之间的相互关系,作者对采自4省5个地区瑞香狼毒的茎、叶、花部位进行内生真菌的分离和纯化,通过形态学和分子生物学方法鉴定种属。结果表明,瑞香狼毒中共分离到21株内生真菌,19株菌分属7纲8目9科8 属,2株未鉴定种属,所有从瑞香狼毒分离到的内生真菌中链格孢属(Alternaria sp.)8株,占总分离菌株的42%,为瑞香狼毒的优势菌株,除1株粪壳菌纲(Sordariomycetes sp.)和8株链格孢属(Alternaria sp.)外,其余菌属均首次从瑞香狼毒中分离得到。

Abstract:

To explore the classes and distribution characteristics of endophytic fungi in Stellera chamaejasme and further explain the connection between fungal endophytes and the toxin synthetism,allelopathy and stress resistance formation,the endopytic fungi in the stems,leaves and flowers of Stellera chamaejasme were isolated,purified and identified through morphological and molecular methods.Among 21 isolates obtained from Stellera chamaejasme,19 strains were identified to belong to 8 genera,9 families,8 orders and 7 classes,and 2 strains were unidentified.Eight strains of fungi were identified as Alternaria sp.,and take 42% of all strains isolated and were the dominant fungal.Except for 1 Sordariomycetes sp.and 8 Alternaria sp.,other species were all first isolated from Stellera chamaejasme.
