Abstract

The campos rupestres (CRs) in eastern Brazil are characterized by rocky outcrops and nutrient-poor soils. These environments harbor a unique flora adapted to adverse conditions, including severe droughts and phosphorus deficiencies. The Velloziaceae family, which dominates this region, stands out for its varied strategies for drought adaptation, such as dehydration prevention and desiccation tolerance. In a previous study, we identified bacteria associated with these plants' drought adaptation strategies. These bacteria can act in the plant's survival under adverse conditions.Furthermore, microorganisms have the potential to be used in agriculture as bioinoculants, offering a low-cost and environmentally sustainable alternative to conventional fertilizers. In this postdoctoral project, we will use genome-resolved metagenomics to elucidate the metabolic potential of key microorganisms associated with plant drought strategies. Concurrently, we will apply metatranscriptomics to reveal gene expression dynamics and regulation of selected microorganisms. Our goal is to unravel the mechanisms of plant-microorganism interaction in natural environments subjected to water and nutrient stress conditions. With this knowledge, we hope to develop technologies that enhance plant tolerance to climate stresses, promoting the use of genes and bioinoculants.
