Effects of low atmospheric CO2 and elevated temperature during growth on the gas exchange responses of C3, C3–C4 intermediate, and C4 species from three evolutionary lineages of C4 photosynthesis

Abstract

This study evaluates acclimation of photosynthesis and stomatal conductance in three evolutionary lineages of C3, C3–C4 intermediate, and C4 species grown in the low CO2 and hot conditions proposed to favo r the evolution of C4 photosynthesis. Closely related C3, C3–C4, and C4 species in the genera Flaveria, Heliotropium, and Alternanthera were grown near… (More)
