Comment
No 'y-type' proteins from the Glu-A1 locus have been demonstrated in hexaploid wheat (790), although they are found in diploid wheats (1126, 579), and sequencing experiments have shown the presence of a terminating sequence inside the transcribed portion of the gene (255). The gene coding for 'x-type' proteins within Glu-A1 is also often silent (790, 290).
There is a possibility that Glu-A1 alleles i, j (1116) and k (327) correspond to alleles d, e, f or g that were published shortly earlier (1126). Glu-A1m (1120) has been changed to n, because the m allele in 754 has precedence. Allele n (1120) has been changed to o. An earlier reference to an allele designated Glu-A1d (1014) has been withdrawn (787). There appears to be a minor band associated with subunit 2* encoded by Glu-A1b (1109); this may be the same as a band named A5 in 290. Six combinations involving 5 HMW subunits [1A (u-z)] are listed in 290, from a study of 109 genotypes including representatives of botanical varieties. A number of alleles in T. turgidum var. dicoccoides populations were described, 12 at Glu-A1-1 and 3 at Glu-A1-2 (579).
Hexaploid stocks: various accessions in addition to Chinese Spring (290).
