Explanation:
Mesophyll conductance is a vital component of photosynthesis, whose importance for accurate characterization of photosynthetic limitations has increased during the last two decades. Carbon dioxide diffusion across the leaf mesophyll is a complex process implying both biochemical and anatomical factors. Among them, aquaporins, chloroplast distribution, and cell wall thickness are its principal determinants. In the last decade, mesophyll conductance has received increased attention as one of the key players in determining photosynthesis under water stress conditions, and also as a target for improving plant productivity and water use efficiency. This chapter will focus on the response of mesophyll conductance to water stress and recovery, including drought acclimation, and will show its importance in constraining photosynthesis under water-limited conditions. Moreover, the possibilities that mesophyll conductance offers for yield and leaf water use efficiency improvement will be discussed.
