Expression patterns of the PMEs family in G. raimondii, G. arboreum and G. hirsutum. a Heatmap showing the clustering of 135 PMEs of G. hirsutum across five tissues (ovules at 0 DPA, 3 DPA, 6 DPA, 10 DPA, and 15 DPA; mentioned at the top of each lane). b Heatmap showing the clustering of 80 PMEs of G. arboreum across five tissues (ovules at 0, 3, 6, 10, and 15 DPA; mentioned at the top of each lane). c Heatmap showing the clustering of 78 PMEs of G. raimondii across five tissues (ovules at 0, 3, 6, 10, and 15 DPA; mentioned at the top of each lane). d Expression of 11 (G. hirsutum) PMEs is predominantly expressed at 15 DPA. e Expression of 5 (G. arboreum) PMEs is predominantly expressed at 15 DPA. f Expression of 3 (G. raimondii) PMEs is predominantly expressed at 15 DPA. The color scale at the bottom of the dendrogram shows the relative expression levels. RNA-seq data under the series accession number SRA180756 was obtained from the NCBI Sequence Read Archive (SRA) database
