What does the nr5S DNA multigene family tell us about the genomic relationship between Dasypyrum breviaristatum and D. villosum (Triticeae: Poaceae)?
Mol Genet Genomics. 2014 Aug; 289(4):553-65.MG

Abstract

The genus Dasypyrum contains two species: the annual and widespread D. villosum (2x = 2n = 14) and the perennial and generally rare D. breviaristatum (2x = 2n = 14 and 4x = 2n = 28). The origin of the latter and its genome constitution have been subject of several studies. There is agreement that the genome of the diploid D. villosum (VV) is different from the diploid cytotype of D. breviaristatum (VbVb), but there is no agreement of the constitution of the tetraploid cytotype, specifically whether is it an autotetraploid or an allotetraploid. This is a long-standing disagreement that this study aims to resolve using the 5S nrDNA as a genomic marker. Our studies suggest that the 4x D. breviaristatum is an allotetraploid (VVVbVb).
