Physiological analysis of transgenic and wild-type plants under normal and cold stress conditions.
Comparison of photosynthesis (a), transpiration (b), intercellular CO2 rate (c) and stomatal conductance (d) in the leaves of transgenic and wild-type plants under normal and cold stress conditions. Six-week-old seedlings of transgenic lines (T2 generation) and wild-type were treated under cold 4 or 25 °C (control) for 3 d. Values in (a–d) represent the means ± SE of three biological replicate samples. Each replicate sample was composite of leaves from three seedlings. C39, C65 and C75 represent three independent ShCML44 transgenic tomato lines. WT represents the wild-type AC. Asterisks indicate significant differences between transgenic lines and wild-type. *P < 0.05; **P < 0.01 Dunnett’s multiple comparisons test.
