Characterization of Seed Endophytic Microbiota in Pinus massoniana.

ABSTRACT: Seed endophytic microbiota are crucial for plant early development and stress resistance. Pinus massoniana is a key ecological and economic tree species in China, yet it is severely threatened by pine wilt disease (PWD). However, the community composition of P. massoniana seed endophytic microbiota and the persistent symbiosis formed via vertical transmission in seeds remain unclear. We analyzed the endophytic bacterial and fungal microbiota of P. massoniana seeds from four geographic regions using high-throughput 16S rRNA and ITS sequencing to characterize community structure, diversity, and functional potential, providing a basis for endophytic microbiota-based strategies to enhance resistance to PWD. Results showed that both alpha and beta diversity analyses indicat
