Phylogeny of Neotyphodium endophyte from western Chinese Elymus species based on act sequences

Abstract:

Abstract:［Objective］ We analyzed phylogenetic relationships between asexual endophytes isolated from western Chinese Elymus species.［Methods］ Fifteen act sequences were cloned from asexual endophytes of the western Chinese Elymus species．The phylogenetic tree and network topology structure were constructed using act sequences obtained and Genbank.［Results］ The act sequences from asexual endophyte were single-copy gene．The western Chinese asexual endophye (Neotyphodium spp.) has a different origination from the North American sexual endophyte (Epichlo elymi) from Elymus species，but there is a closer relationship between Neotyphodium spp. and Neotyphodium chisosum from North American Achnatherum eminens．Further，endophyte gene-flow exists between sexual Neotyphodium chisosum from North American Achnatherum eminens (Hap 8) and asexual Neotyphodium sp．from western Chinese Elymus species (Hap 3)．
