Table 2 Tissue-specific expression of SG19 MYBs in B. napus. The tissue-specific expression of the identified MYB21 and MYB57 homologs in B. napus is presented in mean transcripts per million (TPMs). The number of analysed data sets per tissue is stated in brackets (n = X). Intensity of the blue colouration indicates the expression strength (darker = stronger expression). Abbreviations: weeks after pollination (WAP), days after pollination (DAP), days after flowering (DAF), days (D), shoot apical meristem (SAM)
