Plant Respiration Responses to Elevated CO2: An Overview from Cellular Processes to Global Impacts

Abstract

Earth is currently going through a period of unprecedented, exponential change. As a result, the world's flora are experiencing novel environmental conditions. One of the most steady, ongoing global changesGlobal change is the rise in atmospheric carbon dioxide (CO2). Atmospheric CO2 levels are the highest they've been in 650,000 years and are continuing to increase. The rate at which land plants take up and release CO2 through photosynthesis and respiration, respectively, will significantly influence the trajectory of atmospheric CO2 Atmospheric CO2 change in the future. This chapter explores the physiological mechanisms underlying the response of plant CO2 release (i.e., respiration) to changing atmospheric CO2 concentrations. Both short- (seconds to minutes) and long- (weeks to years) term responses are discussed. Over relatively short timescales, CO2 can alter respiratory physiology, but counterbalancing responses may result in no change in gross respiration. Longer-term responses
