Fig. 3From: Sixteen kiwi (Apteryx spp) transcriptomes provide a wealth of genetic markers and insight into sex chromosome evolution in birds (a) Heat map and cluster dendogram showing differential gene expression between little spotted kiwi (LSK) and rowi. Green and red indicate low and high expression, respectively; data are normalized per gene and sample. Mean upregulation of genes in LSK relative to rowi (1753 genes) and vice versa (1331 genes) was ~8 and 5 fold and ranged from 2 to 701 fold per gene. (b) Biological process gene ontology (GO) assignments for genes significantly upregulated in LSK and rowi. Data are presented for GO terms representing 3% or greater of assignments for at least one species and are weighted by the number of genes with GO terms per speciesBack to article page
