Abstract

The increase in atmospheric concentration of carbon dioxide (CO2), the main greenhouse gas, is unambiguous and not an isolated event, accompanied by increases in global average temperature and changes in precipitation patterns. Among the important factors to be understood in this context are changes in water relations and the production of carbon skeletons through photosynthesis, processes closely influenced by the atmospheric availability of CO2. In Brazil, coffee is one of the most important traded commodities. However, there are few studies in the country about the impacts of increased CO2 concentration associated with other abiotic factors, such as water, on water physiology and carbohydrate accumulation. The aim of this project is to evaluate the influence of high atmospheric CO2 concentration (high [CO2] atm) under open top chamber (OTC) conditions on the interaction of CO2 (high [CO2] atm) x water availability using RNA sequencing. high performance and metabolomic analysis. These results will be important in identifying factors that may mitigate the consequences of climate change scenarios on coffee cultivation practices. (AU)
