Filtration results for the four species compared in this study

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

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
