Article
The key role of cell walls in setting mesophyll conductance to CO2 (gm) and, consequently, photosynthesis, is reviewed. First, the theoretical properties of cell walls that can affect gm are presented. Then, we focus on cell wall thickness (Tcw) reviewing empirical evidence showing that Tcw varies strongly among species and phylogenetic groups in a...
Article
Ensuring global food security is a worldwide major concern considering the predicted climate change scenarios for the main agricultural regions of the world. Stomatal conductance (gs) and mesophyll conductance (gm) are major drivers limiting photosynthesis (A). Both conductances frequently impose about two-thirds of the total photosynthetic limitat...

Enhanced photosynthesis is strictly associated with to productivity and it can be accomplished by genetic approaches through identification of genetic variation. By using a Solanum pennellii introgression lines (ILs) population, it was previously verified that, under normal [CO2], IL 2-5 and 2-6 display increased photosynthetic rates by up to 20% i...
Article
Cell wall thickness is widely recognized as one of the main determinants of mesophyll conductance to CO2 (gm). However, little is known about the components that regulate cell wall effective CO2 diffusivity (i.e. the ratio between actual porosity and tortuosity, the other two biophysical diffusion properties of cell walls). The aim of this study wa...
Article
Full-text available
Besides stomata, the photosynthetic CO2 pathway also involves the transport of CO2 from the sub-stomatal air spaces inside to the carboxylation sites in the chloroplast stroma, where Rubisco is located. This pathway is far to be a simple and direct way, formed by series of consecutive barriers that the CO2 should cross to be finally assimilated in...
