Comparison of leaf respiration parameters in well-watered WT and CMSII plants, determined with the Li-6400 and IRMS system

Respiration parameter	WT	CMSII	Ratio CMSII/WT
Rl (μmol CO2 m−2 s−1)a	0.45±0.04	0.66±0.07	1.5*
Rdc (μmol CO2 m−2 s−1)a	1.50±0.05	1.81±0.08	1.2*
Vt (Rd) (μmol O2 m−2 s−1)	0.89±0.06	1.30±0.10	1.5*

Means and standard errors of at least four plants are shown. Asterisks indicate significant differences (P ≤0.05) between WT and CMSII for each parameter. For details see Materials and methods.

^aThese respiration parameters have been determined in leaves of another set of WT and CMSII plants, which were grown under similar conditions as the well-watered plants used for the V_t measurement.
