Resources and species diversity of the phyllosphere yeasts from the Yandang Mountains in Zhejiang Province
摘要
Abstract
Phyllosphere yeasts from the Yandang Mountains were investigated to reveal their resources and species diversity.The phyllosphere yeasts from the focal region were isolated and purified in a potato dextrose agar (PDA) plate and their classification statuses were defined according to their 26S rDNA D1/D2 sequences and the phylogenetic relationships of the cultures,and then the composition,distribution,and diversity of the phyllosphere yeasts were analyzed in detail.In total,1118 phyllosphere yeasts were isolated from the Yandang Mountains and identified as 56 known groups and 19 proposed new species,among which 38 groups were common.The common yeast species were widely distributed among 25 genera.Of these,the Derxomyces consisted of five species,the Sporobolomyces consisted of three species,the Bannoa,Bulleribasidium,Rhodosporidiobolus,Symmetrospora,Taphrina,Tilletiopsis,and Udeniomyces each consisted of two species,whereas the Bullera,Coniochaeta,Coniosporium,Cryptococcus,Elsinoe,Erythrobasidium,Fellozyma,Golubevia,Kockovaella,Koadoa,Leucosporidium,Moesziomyces,Oberwinklerozyma,Phyllozyma,Ruinenia,and Saitozyma each consisted of one species.According to the relative frequency of the common groups,Derxomyces mrakii had an obvious distribution dominance.At the same time,the stability and variation range of the 26S rDNA D1/D2 sequence among the different strains of D.mrakii were discussed.Based on a comparison of the composition and similarity of common phyllosphere yeasts in the Yandang Mountains,it can be speculated that the distribution of yeast species within geographically close regions might have more similarities.The majority of the phyllosphere yeasts in Yandang Mountains were isolated through analyzing the species accumulation curves based on the species and numbers of common phyllosphere yeasts.Therefore,this study reflects resources and species diversity of the phyllosphere yeasts from the Yandang Mountains.关键词
