  ”Science Bulletin” recently published an online research paper entitled”Using Endophytic Fungi in Grasses to Create New Barley Germplasm” by the Nanzhibiao Academician team of Lanzhou University. This study used the excellent endophytic fungi strains of Hordeum brevisubulatum as materials, and inoculated them into cultivated barley (Hordeum vulgare) Chaiqing No. 1 naked barley and Yangsimai No. 1 barley through a large number of artificial inoculation studies. Two varieties, created a new germplasm of wild barley endophytic fungus Epichlo bromicola-barley that can be inherited stably. Compared with the uninoculated control, the above-ground biomass and grain yield per plant of the new barley germplasm after inoculation increased by 46%and 22%, and the growth period was advanced by 5 days. Plant and grain yield increased by 37%and 28%, respectively. Using endophytic fungi for germplasm innovation, only some turfgrass and a few pastures have been successful. This study first inoculated grass endophytic fungi into cultivated crops, and obtained a new species of endophytic fungus-barley symbiont that can be stably inherited quality. This kind of breeding has opened up a new research idea for breeding. The review experts of the paper all believe that the use of wild grass endophytic fungi to create new germplasm for stress-resistant and high-yielding pasture and cultivated crops is an innovative direction for pasture and crop breeding. The application of Epichlo? genus endophytic fungi for targeted improvement of cereal crops is of great significance to the development and application of agricultural and forestry resources.
  Academician Nan Zhibiao of the School of Grassland Agriculture Science and Technology of Lanzhou University is the corresponding author of the paper, and Professor Li Chunjie is the first author.
