Seasonal bacterial profiles of Vellozia with distinct drought adaptations in the megadiverse campos rupestres.

ABSTRACT: Microbial communities can vary as a function of seasonal precipitation and the phenotypic characteristics of the prevailing plant species in an ecosystem. The Brazilian campos rupestres (CRs) host a unique flora adapted to harsh conditions, including severe droughts and nutrient-poor soils. Velloziaceae, a dominant angiosperm family in CRs, exhibit contrasting drought adaptive strategies, prominently desiccation tolerance and dehydration avoidance. Here, we created a comprehensive dataset of microbial composition and dynamics of bulk soil and distinct plant compartments (leaf blade, dry sheath, aerial root, and underground root) from two desiccation-tolerant and two dehydration-avoiding, non-desiccation-tolerant Vellozia species, across four seasons (beginning and end of rainy and dry seas
