STEM analysis of PeBBX genes. a STEM analysis of PeBBX genes. The yellow boxes indicate significant gene expression. All 10 profiles are drawn with profile numbers denoted at the top left. The dashed line indicates the trend of expression over time, and the value in the lower-left corner is the P-value for its corresponding significance level. The image on the right shows the manifestations of significantly expressed genes. b Expression patterns of genes in profile 9 that are highly positively associated with shoot growth stages. A single asterisk indicates that the level of the gene expression was significantly different (t-test, p < 0.05). Double asterisks indicate that there is a significant difference (t-test, p < 0.01). Error bars represent standard deviations of the means of three independent replicates
