Comment
The Glu-1 loci, which are compound, encode HMW glutenin subunits. Each Glu-1 locus in hexaploid wheat contains two genes, the products of which were described as 'x-type' and 'y-type' based on differences in molecular weight and isoelectric point (790). Other evidence has shown these gene products to differ in electrophoretic fingerprint pattern (798) and cysteine content (730), and the genes themselves to differ in nucleotide sequence (1068, 1034, 255). Although early evidence suggested up to 6 genes in total at each locus (1069, 255), it appears likely that only a single copy of each gene is present at the 1AL, 1BL, and 1DL loci (340). The symbols for the genes within the Glu-1 loci encoding 'x-type' and 'y-type' proteins are Glu-1-1 and Glu-1-2, respectively [rather than Glu-1x and Glu-1y (1068)]. The genes are closely linked but recombination has been observed between Glu-B1-1 and Glu-B1-2 with a frequency of 3 in 3,450 (789). The gene order, relative to the centromere, has not been ascertained. A system of naming the Glu-A1-1, Glu-A1-2, Glu-B1-1 and Glu-B1-2 alleles in T. turgidum var. dicoccoides is given in 577.
