Fig. 1 Phenotypes of the wild type (WT) and tsa2 mutant A, B, C: seedling stage (A), tillering stage (B), and mature stage (C) of the wild type (WT) and tsa2 mutant seedled at a daily average temperature of 22°C; D, E, F: seedling stage (D), tillering stage (E), and mature stage (F) of the wild type (WT) and tsa2 mutant seedled at a daily average temperature of 28°C; G, H, I, J, K, L: corresponding to the leaves in A, B, C, D, E, F, respectively. 1, 2, 3, and 4 in the figures H, I, K, and L represent the first, second, third, and fourth fully expanded leaves from topmost leaf, respectively. A and D, Bar = 2 cm; B and E, Bar = 6 cm; C and F, Bar = 13 cm; G-L, Bar = 0.7 cm.
