Fig. 6From: Comparison of the cytoplastic genomes by resequencing: insights into the genetic diversity and the phylogeny of the agriculturally important genus BrassicaA refined model of U’s Triangle. Ellipses of single and double lines represent three basic diploid and three tetraploid species in Brassica genus. Diffusion of the corresponding cytoplasmic haplotypes were indicated by the arrows. Ellipse of dashed lines represents the close (diploid) species in other genera which can be used to create extensive germplasms with novel allotetraploid genomes and various cytonuclear combinationsBack to article page
