The quantitative real-time polymerase chain reaction (qRT-PCR) analysis of expression levels of 15 selected genes in different tissues of seven colour-variant radish genotypes. Three independent biological repeats were performed, and all data points were the means of three biological replicates ± standard error (SE). Variance analysis was carried out to evaluate differences between difference samples for root and leaf followed by multiple comparison using Duncan’s significant ranges least significant difference (SSR). Different letters indicate significance at p = 0.05 level. Of those, a, b, c, d, e, f, g means in a column with no superscript letter in common differ (P < 0.05), similar letters or common letters are not significantly different at the 5% level by Duncan’s multiple range test
