“…We previously examined the expression of photosynthetic genes, rbcS and cab, which encode the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and light har vesting chlorophyll a/b binding protein, respectively, in the emerging leaves and lamina joint of rice (Tsutsumi et al, 2006(Tsutsumi et al, , 2007. The photosynthetic genes were expressed in both bundle sheath and mesophyll cells in the immature basal region of the emerging leaves whereas the genes were expressed only in mesophyll cells in more mature middle and tip regions.…”
