Have We Selected for Higher Mesophyll Conductance in Domesticating Soybean?

ABSTRACT: Soybean (Glycine max) is the single most important global source of vegetable protein. Yield improvements per unit land area are needed to avoid further expansion onto natural systems. Mesophyll conductance (g_m) quantifies the ease with which CO₂ can diffuse from the sub-stomatal cavity to Rubisco. Increasing g_m is attractive since it increases photosynthesis without increasing water use. Most measurements of g_m have been made during steady-state light saturated photosynthesis. In field crop canopies, light fluctuations are frequent and the speed with which g_m can increase following shade to sun transitions affects crop carbon gain. Is there variability in g_m within soybean germplasm? If so, indirect selection may have indir
