图2 IbNAC72基因的表达分析 A: IbNAC72基因在栗子香试管苗不同组织中的表达分析; B: IbNAC72基因在栗子香大田植株不同组织中的表达分析; C: IbNAC72基因在100 mmol L-1 NaCl胁迫处理下的表达分析; D: IbNAC72基因在20% PEG-6000胁迫处理下的表达分析。数据表示为平均值 ± SD (n = 3)。采用单因素方差分析法对数据进行统计分析, 柱上不同的小写字母代表柱值在0.05水平差异显著。

Fig. 2 Expression analysis of IbNAC72 A: transcriptional levels of IbNAC72 in different tissues of 4-week-old in vitro-grown Lizixiang plants; B: transcriptional levels of IbNAC72 in different tissues of 3-month-old field-grown Lizixiang plants; C: expression level of IbNAC72 in the Lizixiang plants under 100 mmol L-1 NaCl treatment; D: expression level of IbNAC72 in the Lizixiang plants under 20% PEG-6000 treatment. The error bars indicate ± SD (n = 3). Different lowercase letters indicate significant difference at the 0.05 probability level based on one-way ANOVA.
