From: Small-scale gene duplications played a major role in the recent evolution of wheat chromosome 3B
Comparison of the distributions of older versus more recent wheat non-syntenic genes along chromosome 3B. a “Recent” non-syntenic genes that moved after the divergence of the wheat progenitors (carried by 3B but without homolog on 3A, 3D, or 3H). b “Older” non-syntenic genes that have moved in the Triticeae lineage after divergence with Brachypodium and before the divergence of the wheat progenitors. These are 3B non-syntenic genes with a homolog on 3A, 3D, or 3H. The proportion of older and more recent non-syntenic genes out of the total number of genes was calculated within a 10 Mb sliding window with a step of 1 Mb. The centromeric/pericentromeric region is highlighted in the gray box
