Title	Identification of a 5S rDNA spacer type specific to Triticum urartu and wheats containing the T. urartu genome
Journal	Genome
Year	2000
Volume	43
Pages	250-254
Author	Allaby RG Brown TA
Abstract	Summary: A PCR system was designed to amplify 5S spacer rDNA specifically from homeologous chromosome 1 in a variety of species representative of the Aegilops and Triticum genera. Two polymerase chain reaction (PCR) primer combinations were used, one of which appears to be apomorphic in nature and specific to chromosome 1A in Triticum urartu and tetraploid and hexaploid wheats containing the AA genome donated by T. urartu. The value of studying single repeat types to investigate the molecular evolution of 5S-rDNA arrays is considered
