A systems approach to understand the impact of climate changes in Coffea spp.

Abstract

The increase in the atmospheric concentration of carbon dioxide (CO2), the main gas responsible for the further greenhouse effect, is unequivocal and not an isolated event, accompanied by increases in global mean temperature and changes in precipitation patterns. Among the important factors to be understood in this context are changes in water relations and production of carbon skeletons through photosynthesis, processes intimately influenced by atmospheric CO2 availability. In Brazil, coffee is one of the most important traded commodities. However, there are no studies, on the impacts of increased concentration CO2 associated with other abiotic factors such as water, in the physiology of water relations and accumulation of carbohydrates in coffee. The aim of this project is evaluate the influence of high atmospheric CO2 concentration (high [CO2]atm) under conditions of open-top chambers (OTC) in the interaction high [CO2]atm x water availability, using high-throughput RNA sequencing and metabolomics analysis. These results will be important to identify interacting factors that may alleviate the consequences of climate change scenarios in coffee cultivation practices. (AU)
