Evidence that Aco-B2 and Aco-D2 of Triticum aestivum are located in chromosomes 4B and 4D.

Studies designed to determine the chromosomal locations of variant Aconitase-2 alleles of Triticum aestivum disclosed that Aco-B2 and Aco-D2 are not located in chromosomes 5B and 5D, as formerly reported. Reinvestigation of the chromosomal locations of the genes provided strong evidence they are instead located in chromosomes 4B and 4D. Also, four Aco-B2 alleles were identified but no variant Aco-D2 alleles were detected.
