Endophytic Fungal Community of Pinus densiflora Infected by Different Incidences of Sphaeropsis sapinea in a Mixed Coniferous Forest

Year: 2019

Type: article

Abstract: Shoot blight of pine caused by Sphaeropsis sapinea is a serious threat to the health of Pinus densiflora.However, little is known about the effect of S. sapinea on the structure of endophytic fungal communities in needles of P. densiflora.In this study, the diversity and structure of the endophytic fungal communities associated with asymptomatic and symptomatic needles of P. densiflora were investigated.Needles of P. densiflora were sampled from mixed coniferous forests, and high through-put sequencing was used to determine the diversity and community structure of endophytic fungi.The results demonstrated that endophytic fungal abundance increased when the lesion length was longer, and the endophytic fungal diversity showed an upward trend as the infection of S. sapinea worsened.The dominant genera of endophytic fungi in asymptomatic needles of P. densiflora in mixed coniferous forest was Paraconiothyrium and Selenophoma.Cenangium is considered to have a certain association with S. sapinea infection in the endophytic fungal community.The results showed that S. sapinea infection affected the endophytic fungal community in needles of P. densiflora in a mixed coniferous forest.
