Deciphering the anthosphere and endosphere microbiome of wild Rosaceae plants for cold-adapted plant growth promoting bacteria
Cold stress is one of the main limiting factors for fruit crop production worldwide. Plants and their associated microbial communities have developed complex adaptation strategies against different abiotic stresses, cold stress included. Plants growing in cold regions, such as alpine and sub-alpine...

Cold stress is one of the main limiting factors for fruit crop production worldwide. Plants and their associated microbial communities have developed complex adaptation strategies against different abiotic stresses, cold stress included. Plants growing in cold regions, such as alpine and sub-alpine regions, are hypothesized to survive cold stress thanks to symbiosis with endophytic microorganisms. However, the structure and function of endophytic microbial communities associated with such plants are poorly understood. Our aim is to taxonomically and functionally characterize the endophytic bacterial communities associated with three wild cold-adapted Rosaceae plants (i.e. Geum montanum, Alchemilla sp., and Dryas octopetala) from alpine region. Plant samples were collected from seven different sites in Italy from two expositions (North and South).
