Tissue-specific expression patterns of GmHDAC genes. The x-axis represents different tissues or organs. The y-axis shows the gene expression levels after normalization to reference gene GmCYP2. Roots, cotyledons, epicotyls, and hypocotyls of 5-day-old plants and leaves, stems of 14-day-old plants, young flowers and seeds were collected for total RNA isolation. Quantitative RT-PCR was performed using gene-specific primers. Data are the mean ± SEM of three independent experiments
