Determinations of various physiological parameters and biomass production in WT and transgenic tomato plants. a-e Physiological analysis of WT and SiFBA5 transgenic plants under normal temperature (25 °C) and cold stress (16, 10, and 4 °C), a malondialdehyde (MDA), b superoxide dismutase (SOD), c peroxidase (POD), d catalase (CAT), and e total chlorophyll content. f Maximal efficiency of PSII photochemistry (Fv/Fm), g net photosynthetic rate (Pn), h biomass. Mean ± SD was obtained in one experiment with three biological replicates. Asterisks indicate significant differences between WT and transgenic plants (*P < 0.05; **P < 0.01). One-way ANOVA was used to compare the statistical difference between measurements (P < 0.05)
