From: Intergenomic gene transfer in diploid and allopolyploid Gossypium
Hypothetic evolutionary model showing the change of norgDNAs during allopolyploidization of cotton species. a Schema graph showing the mitochondrial-to-nuclear IGT events during the allopolyploidy of Gossypium. Genes in green color denote pseudogenes. Genes in blue rectangular strip transferred only in D5 after the differentiation of D5 and A2. Genes in purple rectangular strip transferred only in AD2 after the differentiation of AD1 and AD2. b Schema graph showing the chloroplast-to-nuclear IGT events during the allopolyploidy of Gossypium. Genes in the same gray boxes belong to one functional classification. Genes in green color denote pseudogenes. The genes in blue and purple boxes transferred after the differentiation of D5 and A2 genomes
