Fig. 9

Heat map representation of MADS-box gene expression in E. pusilla. The FUL-, AP3-, PI-, AG-, STK-, SEP- and ALG6- like copies were retrieved from different gene lineage clades during two stages of floral development. Expression of the MADS-box genes was normalised to the geometric mean of three reference genes Actin, UBI2 and Fbox. The relative gene expression was normalised with the CTRL sample (= flower buds from floral stages 1-4). The scales for each gene and developmental stage are independent of each other and set to 1 for the highest value. Abbreviations: lse = lateral sepal; mse = median sepal; cl = callus; pe = petal; fs = fertile stamen; gm = gynostemium
