图7 GhMADS7-RNAi转基因植株中A、B类基因表达量检测 A: A类基因在GhMADS7-RNAi转基因植株中表达量水平; B: B类基因在GhMADS7-RNAi转基因植株中表达量水平。YZ1: 野生型植株; iGhMADS7: 植株GhMADS7转基因植株。F<5: 花蕾长度在5 mm以下; F5-6: 花蕾长度为5~6 mm; F6-7: 花蕾长度为6~7 mm; F7-8: 花蕾长度为7~8 mm; F8-9: 花蕾长度在8~9 mm; F>9: 花蕾长度在9 mm以上。误差线表示3次重复的误差。*, **分别表示在0.05和0.01水平显著差异。

Fig. 7 Relative expression levels of A and B type genes in GhMADS7 transgenic plants A: the expression levels of A genes in GhMADS7-RNAi transgenic plants; B: the expression levels of B genes in GhMADS7-RNAi transgenic plants. YZ1: wild type plant; iGhMADS7: suppression of GhMADS7 transgenic plant. F<5: the length of flower bud is less than 5 mm; F5-6: the length of flower bud is 5-6 mm; F6-7: the length of flower bud is 6-7 mm; F7-8: the length of flower bud is 7-8 mm; F8-9: the length of flower bud is 8-9 mm; F>9: the length of flower bud is above 9 mm. The error bars represent deviations of three replicates. *, ** mean significant differences at the 0.05 and 0.01 probability levels.
