Diversity Analysis of Rust Fungi in Yunnan Province
摘要
Abstract
Located in the southwesten China,Yunnan Province is a well-known place for its rich biodiversity including the rust fungi,as obligate biotrophic parasites,owing to its distinctive geographical environment and climatic conditions.In this study,over 280 specimens of rust fungi collected from Yunnan area were identified.Combining with the results reported before,it is now known that at least 405 species of the rust fungi existed in the Yunnan Province,which could be divided into 20 families and 42 genera.Among the above fungi,Austropuccinia psidii(G.Winter)Beenken,a rust fungus that parasitizes guava,is a new record of species reported so far from Yunnan Province.The dominant family is Pucciniaceae occupying 54.0％of the total number of families,followed by Coleosporiaceae accounting for 8.6％.Rust fungi parasitizing the living host of herbaceous plants revealed the highest diversity,with 15 genera and 242 species,including 152 species from the genus Puccinia.Rust fungi collected from the shrubs contained 19 genera and 78 species,meanwhile,in which the genus Phragmidium parasitizing the flowering plants of genera Rosa and Rubus showed the largest number of species(16 species in total).Rust fungi detected from the trees were divided into 23 genera and 62 species,on the other hand,in which Melampsora was known as the main genera parasitizing Populus,Salix and Euphorbia.Our study systematically demonstrates the richness of species diversity of rust fungi in Yunnan Province that indicates,on the other hand,the existence of a large number of undiscovered tropical rust species potentially still hiding within this area,including those records of the genus Ravenelia not yet documented in China.The above findings provide a scientific basis not only for the taxonomic study of rust fungi but also for the precise prevention and control of rust diseases.Most importantly,these finding should hold great implications usefully for the future protection of the rich plant resources as well as the maintenance of the stability of forest ecosystems in Yunnan Province.关键词
