GMA photorespiratory bypass increases photosynthetic rate and capacity in rice.

(A) Balance of Rubisco responses to CO₂/O₂ in GMA rice. RuBP, ribulose-1,5-bisphosphate.

(B) Net photosynthetic rate (P_N) was measured at 800 μmol m⁻² s⁻¹.

(C) Response of P_N to CO₂ concentration at 1200 μmol m⁻² s⁻¹ photon flux density (PFD) and 30°C.

(D) Response of P_N to light intensity at 30°C under normal air conditions.

(E and F) Light saturation point (LSP) and light-saturated photosynthetic rate (Amax) were fitted based on the light-response curves.

(G) Glycine/serine ratio in WT and GMA lines. The amino acid values were normalized per gram FW in WT and GMA lines.
