TGA7 expression is regulated by several pathways. a TGA7 expression in photoperiod-pathway mutants at 9 DAG. b TGA7 expression after a gibberellin (GA) treatment. WT seedlings were grown under SD conditions for 2 weeks and then treated with 100 µM GA₃ or 0.1 % ethanol weekly. Seedlings treated for 3 (W3) and 5 weeks (W5) were collected for further analyses. c TGA7 expression after a vernalization treatment. The seedlings were vernalized at 4 °C for 8 weeks. The 9-day-old seedlings were collected for further analyses. d TGA7 expression in autonomous-pathway mutants at 9 DAG. e The TGA7 expression level in WT seedlings grown at 16℃, 23℃, and 27℃ under LD conditions until 9 DAG. f TGA7 expression in WT, svp-41, and 35 S:SVP plants grown at 16 and 23 °C under LD conditions until 9 DAG. Asterisks indicate significant differences (Student’s t test, p ≤ 0.05). g Flowering times of wild-type, svp-41, and tga7 plants grown at 16 °C, 23 °C, and 27 °C under LD conditions. The ratios of flowering time between 16 and 23 °C (16 °C/23°C) and between 23 and 27 °C (23 °C/27°C) for all the genotypes are indicated in the attached table. Values were scored from at least 15 plants of each genotype. Error bars indicate standard deviations
