Amplicon sequencing and culture-dependent approaches reveal core bacterial endophytes aiding freezing stress tolerance in alpine Rosaceae plants.

ABSTRACT: Wild plants growing in alpine regions are associated with endophytic microbial communities that may support plant growth and survival under cold conditions. The structure and function of endophytic bacterial communities were characterized in flowers, leaves, and roots of three alpine Rosaceae plants in Alpine areas using a combined amplicon sequencing and culture-dependent approaches to determine the role of core taxa on plant freezing stress tolerance. Amplicon sequencing analysis revealed that plant tissue, collection site, and host plant are the main factors affecting the richness, diversity, and taxonomic structure of endophytic bacterial communities in alpine Rosaceae plants. Core endophytic bacterial taxa were identified as 31 amplicon sequence variants highly prevalent across all pl
