Diversity of endophytic fungi in roots of grapes in Yantai
Diversity of endophytic fungi in roots of grapes was studied in order to understand the composition and diversity of endophytic fungi from grape in Yantai. The four varieties of healthy grapevine were collected from Changyu Castel Chateau of Yantai and the endophytic fungi of their roots were isolated. The identification was adopting the combination of morphological observation and ITS sequence determination. A total of 1331 strains of endophytic fungi was isolated. As a result of 19 genera were obtained, of which Fusarium(amounting to 33.9%of the total), Ilyonectria(17.35%) and Cylindrocarpon(15.7%) were dominant. Diversity index of endophytic fungi from the roots of grapes indicated different abundance and uniformity but assumed similarity to a certain extent.
