Fig. 3.

Expression patterns of genes involved in starch metabolism. Average expression over endosperm development and hierarchal clustering of genes within seven categories related to starch metabolism. A total of 91 genes were visualised after filtering out genes with low expression (keeping only genes with average expression of ≥ 1 TPM for at least one timepoint). Average log₂ TPM expression values (n = 3) were used to illustrate expression, with the same scale used for all categories. Genes in bold were identified as DEGs, and those that were grouped into a global cluster in Fig. 2 are annotated with their cluster number (C0-C8). Details of all starch metabolism genes, including average TPM values, can be found in Supplemental File 5. TPM = transcripts per million, dpa = days post anthesis
