Diversity of endophytic fungi from six dominant plant species in a Pb-Zn mine wasteland in China

Zusammenfassung: | The fungi which cause asymptomatic infections in living plant tissues are called endophytic fungi. They comprise diverse groups of fungi and may protect their host plants against the insect pests and phytopathogens, as well as increase hosts fitness in extreme environments. In order to document the ecological relationship between endophytic fungi and their host plants which grown in heavy metal contaminanted soils, the endophytic fungal diversity, the dominant fungi and their host specificity of six dominant plant species (Arabis hirsuta, Acacia decurrens, Symplocos paniculata, Rabbosia eriocalyx, Arenaria serpyllifolia and Rosa longicuspis) collected from the Huize Pb-Zn mine wasteland of Yunnan Province, southwest China, were investigated. A total of 495 culturable endophytic fungi were isolated from 690 stems and leaf segments of the six plant species. The isolation rate of the endophytic fungi in the six plant species ranged from 0.42 to 0.93, and the mean isolation rate was 0.72. The highest isolation rate appeared in R. eriocalyx, and the lowest isolation rate appeared in Ro. longicuspis. It was found that the isolation rate of the endophytic fungi in the stems was significantly higher than that in the leaves (P |
