Summary of gene expression patterns. The upper panel summarizes results from the current data set and the lower panel summarizes results from Yant et al., 2015. Grey boxes show genes DE between developmental stages. Purple boxes show genes DE between samples with and without spur tissue. Upper panel: Between DS1 and DS5, more genes are commonly up-regulated late in development across all taxa (n=1262) than down-regulated (n=1094). Genes expressed early in development are enriched for GO terms related to mitosis while genes expressed later in development are enriched for GO terms related to oxidation-reduction processes (grey boxes). The number of genes DE between the three spurred taxa and A. ecalcarata increases across developmental stages (purple boxes). Late in development (DS5), genes related to mitosis are over-represented in the spurred taxa, while early in development (DS1-DS4), genes related to oxidation-reduction processes are over-represented in A. ecalcarata. More genes are commonly up-regulated in A. ecalcarata relative to the spurred taxa at all developmental stages (n=453 vs. n=237). Bottom panel: In A. coerulea ‘Origami’, between the 1 mm and 3 mm stages, more genes are up-regulated than down-regulated through development in both blade (n=1415 vs n=1111) and spur (n=1866 vs n=660) tissue (grey boxes). Between blade and spur tissue, a greater number of genes is up-regulated in blade tissue relative to spur tissue at both the 1 mm (n=490 vs n=280) and 3 mm stages (n=1178 vs n=767), and commonly across both stages (n=326 vs n=190; purple boxes). Identifying loci commonly DE across both panels, only 27 genes are commonly up-regulated in ‘blade’ class tissue and only 8 genes are commonly up-regulated in ‘spur’ class tissue
