Flavonoids affect the endophytic bacterial community in Ginkgo biloba leaves with increasing altitude.

ABSTRACT: Altitude affects plant growth and metabolism, but the effect of altitude on plant endophytic microorganisms is still unclear. In this study, we selected 16 Ginkgo biloba trees to study the response of leaves' endophytes to flavonoids and altitude (from 530 m to 1,310 m). HPLC results showed that flavonoids in Ginkgo biloba leaves increased by more than 150% with attitude rising from 530 m to 1,310 m, which revealed a positive correlation with altitude. Ginkgo biloba might regulate the increased flavonoids in leaves to resist the increasing light intensity. 16S rDNA sequencing results showed that the endophytic bacterial communities of Ginkgo biloba at different altitudes significantly differed. Ginkgo leaf endophytes' alpha diversity decreased with increa
