(A) The expression patterns of eight SPL genes in mature sugar beet roots, stems, and leaves were detected using quantitative real-time polymerase chain reaction (qRT-PCR) technology. The lowercase letters above the bars indicate significant differences between treatments (α = 0.05, LSD). The expression level of BvSPL gene was normalized to the expression level of BvACTIN, and its relative expression level was displayed at 0 h, 2 and 24 h. (B) Correlation analysis of the expression of BvSPL genes in mature beet. The expression values of the color gradient mapping from low (blue) to high (red) on the right side of the figure
