Gas Exchange Parameters of Wild-Type and Transgenic Tomato Plants

	A (μmol m−2 s−1)	gs (mmol m−2 s−1)	Ci/Ca
FL11	10.6 ± 0.4	164.0 ± 4.2	0.61 ± 0.03
FL41	9.9 ± 0.2	159.7 ± 5.9	0.63 ± 0.02
Wild type	13.1 ± 0.5	209.3 ± 7.8	0.68 ± 0.03
SDH 14	17.9 ± 0.9	297.5 ± 11.3	0.77 ± 0.02
SDH 43	16.9 ± 0.4	290.4 ± 2.2	0.75 ± 0.02

Instantaneous gas-exchange variables, namely, the net CO₂ assimilation rate (A), stomatal conductance to water vapor (g_s), and internal-to-ambient CO₂ concentration ratio (C_i/C_a) were measured under natural irradiance. Values presented are means ± se of six individual plants per line. Values in bold were determined by the Student's t test to be significantly different (P < 0.05) from the wild type.
