Figure 4. Flower development (like MADS-box genes) and pollen toolkit genes.

Figure 4

a) Phylogenetic tree of type II MADS-box genes in seagrasses and P. acutifolius, including Arabidopsis thaliana (AT) and Oryza sativa (Os) for reference. b) Gene expression patterns for type II MADS-box genes from various organs of Z. marina. Expression values were scaled by log2(TPM+ 1). c) Gene expression patterns for type II MADS-box genes from various organs of P. oceanica. Expression values were scaled by log2(TPM+ 1). d) The flowering ABCE model in Z. marina specifying female and male organs as proposed based on gene expression values (bar heights) from b. e) The flowering ABCE model in P. oceanica specifying female and male organs as proposed based on the gene expression values (bar heights) from c. f) Normalized gene copy numbers for MADS-box and pollen toolkit genes for 4 seagrasses and 19 representative non-seagrass species. Normalization for each gene family was obtained by dividing the number of genes in that gene family for a particular species by the largest gene copy number within that family (considering all species). Genes in black are absent. Taxa are arranged phylogenetically and colored by life form.
