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

Introduction: C photosynthesis is an adaptation that has independently evolved at least 66 times in angiosperms. C plants, unlike their C 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 C photosynthesis greatly alters the relation between CO assimilation and stomatal conductance.

Corrigendum: Activation of CO assimilation during photosynthetic induction is slower in C than in C photosynthesis in three phylogenetically controlled experiments.

Activation of CO assimilation during photosynthetic induction is slower in C than in C photosynthesis in three phylogenetically controlled experiments.

Introduction: Despite their importance for the global carbon cycle and crop production, species with C photosynthesis are still somewhat understudied relative to C species. Although the benefits of the C carbon concentrating mechanism are readily observable under optimal steady state conditions, it is less clear how the presence of C affects activation of CO assimilation during photosynthetic induction.

Methods: In this study we aimed to characterise differences between C and C photosynthetic induction responses by analysing steady state photosynthesis and photosynthetic induction in three phylogenetically linked pairs of C and C species from , , and genera.

The influence of stomatal morphology and distribution on photosynthetic gas exchange.

The intricate and interconnecting reactions of C photosynthesis are often limited by one of two fundamental processes: the conversion of solar energy into chemical energy, or the diffusion of CO from the atmosphere through the stomata, and ultimately into the chloroplast. In this review, we explore how the contributions of stomatal morphology and distribution can affect photosynthesis, through changes in gaseous exchange. The factors driving this relationship are considered, and recent results from studies investigating the effects of stomatal shape, size, density and patterning on photosynthesis are discussed.
