Table 1 Filtration results for the four species compared in this study

From: Small-scale gene duplications played a major role in the recent evolution of wheat chromosome 3B

Species Chr. Number of genes (no ASVs or TEs) Number of genes with at least 1 homolog Number of genes after removing pseudogenes
Triticum aestivum 3B 7,703 6,254 5,125
Brachypodium distachyon 2 4,293 3,804 3,804
Oryza sativa 1 5,070 3,882 3,582
Sorghum bicolor 3 4,555 4,023 4,023
  1. Sequential process of filtration, starting with the total numbers of genes in the syntenic regions of each chromosome after removing transposon related genes and alternative splice variants (ASVs). The numbers of genes with at least 1 homolog are those with a significant BLAST hit (>35 % amino acid identity and >35 % gene overlap) in at least one of the other species
