From: Patterns of homoeologous gene expression shown by RNA sequencing in hexaploid bread wheat
Presence and expression of up to three homoeoloci for wheat genes on group 1 chromosomes. (A) Presence of a gene on 1A, 1B, and 1D homoeologous chromosomes is inferred using nullitetra analysis of RNA-Seq data combined with deletion bin mapping data [58, 63] and chromosome 1 arm-specific assemblies from Wicker et al. [52]. The pie chart shows the number of genes present on one, two or three homoeologous chromosomes, while the Venn diagram shows the number of genes present on each combination of chromosomes. Dashed circles indicate genes present on the corresponding homoeologous chromosome plus at least one other chromosome whose identity cannot be distinguished. (B) Genes with evidence for presence on all three homoeologous chromosomes of group 1 are expressed from at least one, at least two, or all three homoeoloci in shoots (left panel) and roots (right panel) according to the presence of group 1 homoeologue-specific sequences. Grey circles show the number of genes with expression classified as ‘unassigned’ (see also Additional file 15: Table S6).
