A comparison of stomatal conductance responses to blue and red light between C3 and C4 photosynthetic species in three phylogenetically-controlled experiments.

ABSTRACT:

Introduction

C₄ photosynthesis is an adaptation that has independently evolved at least 66 times in angiosperms. C₄ plants, unlike their C₃ ancestral, have a carbon concentrating mechanism which suppresses photorespiration, often resulting in faster photosynthetic rates, higher yields, and enhanced water use efficiency. Moreover, the presence of C₄ photosynthesis greatly alters the relation between CO₂ assimilation and stomatal conductance. Previous papers have suggested that the adjustment involves a decrease in stomatal density. Here, we tested if C₄ species also have differing stomatal responses to environmental cues, to accommodate the modified CO₂ assimilation patterns compared to C₃ specie
