Endophytic bacterial diversity of Vicatia thibetica collected from Xizang and the association with flavonoid accumulation.

ABSTRACT: Vicatia thibetica de Boiss is a unique medicinal and edible plant endemic to Xizang, China. It is one of the five primary root medicines in Tibetan medicine due to its high content of flavonoids. However, the community composition of endophytic bacteria in its various tissues and their potential role in flavonoid accumulation remain unclear. We employed high-throughput sequencing to compare the diversity of endophytic bacteria in the rhizosphere soil and various tissues of V. thibetica collected from three sampling sites in Nyingchi, Xizang. Concurrently, we assessed the types and concentrations of flavonoids present in the roots. Finally, we investigated the relationship between root endophytic bacteria and flavonoid accumulation through correlation analysis. The results indicated that th
