Fig. 3

Anatomical limitations of mesophyll conductance (gm) (a) and the share of the overall gm limitation (b) by cell wall (cw), plasma membrane (pl), chloroplast envelope (en), cytoplasm (cyt) and stroma (st) in rice leaves supplied with NH4+ (AN) or NO3 (NN) under 3 different amounts, low N (0.71 mM, LAN and LNN), intermediate N (2.86 mM, MAN and MNN), and high N (7.14 mM, HAN and HNN). The inset figure shows the anatomical limitations of gm and the share of the overall gm limitation by gas phase. The error bars indicate the standard deviation and at least 15 replicates were conducted for each parameter. Different letters indicate statistically significant differences (P < 0.05) between different treatments
