In the current climate change world scenario, the inevitable reduction of water used in agriculture as well as the increasing of areas under desertification process, impact the actual agricultural practices. In this context, the use of drought tolerant microorganisms, which are able to promote plant growing and protection under drought conditions, is an alternative to fight the impact of climate changes in the environment. Thus, the assessment of mandacaru rizosfera microbiome growing in the caatinga climate conditions is and untapped source of microorganisms and molecules with potential for biotechnology exploration. Moreover, this study shed light in questions related to how the microbiome sustains the host life in extreme environmental conditions. Considering that these microorganisms associated with plants growing in extreme conditions also developed mechanisms for adaptation and survival, the understanding of the microbial community dynamics is basis for the development of strategies for agricultural practices under drought conditions. This project aims to access the of rhizosphere microbiome dynamics from mandacaru in two distinct seasons in the caatinga Brazilian biome by using metagenomics and identify microbial groups associated with the host in drought and high temperature conditions.
