Single-copy gene states after polyploidization. a A proposed model of the status of single-copy genes after polyploidization. All genes belong to single copies in both diploid progenitor genomes, and the status 0 or 1 represents gene loss or retention in tetraploid subgenomes. b Pie charts showing single-copy gene loss in different situations. c The phylogenetic tree shows the relationship in the four genomes. The figure shows that the gene on chromosome A07 of the At subgenome was lost, accompanied by Copia LTR retrotransposon insertion. This gene was present in the other three genomes. The colored boxes indicate coding regions and protein domain information from the Pfam database. d–g Gene characterization with different status. Mean and SE values are indicated
