Fig. 4From: SiFBA5, a cold-responsive factor from Saussurea involucrata promotes cold resilience and biomass increase in transgenic tomato plants under cold stressDeterminations 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)Back to article page
