Expression profiles of LuLEA gene families in flax seed development. a Venn diagram of shared and non-shared numbers of genes of the cultivar Heiya No.14 expressed at 5, 10, 20, and 30 days after pollination; b similar to a but of the cultivar Macbeth; c comparison of LuLEA gene expression levels in every subfamily during seed maturation. Shades of blue color represent lower expression levels, and shades of red color represent higher levels
