Comment
Alleles formerly designated t to x in 939 have been renamed x to ab because allele t in 617 and alleles u, v and w in 754 have precedence. Subunit 8 of Glu-B1b (7+8) is more acidic in isoelectric focusing than subunit 8 of Glu-B1d (6+8) (394). Variation in the mobility of subunits designated 7 has been observed (790), which accords with more recent observations (516, 754). The subunit encoded by Glu-B1v (754) has the same mobility as subunit 7 of Glu-B1c (7+9); it could be the same subunit as 7' encoded by Glu-B1ai (516). Variation in the staining intensity of subunit 7 in different varieties has also been observed (754); possible low gene expression at Glu-B1 has been noted for Glu-B1w, where subunits 6*+8* stain very faintly (814). One of the Glu-B1af subunits has been numbered 26 in 814; 26 was previously used to number the subunit encoded by Glu-A1k (327). Subunit 28 of Glu-B1ag (28+29) (814) is referred to as subunit 19* in 753. Subunit 23 of Glu-B1p (23+18) and Glu-B1ad (23+22) (95) may not be the same subunit as that numbered 23 of Glu-B1l (23+24) (561). Glu-B1z carried by Roccia was numbered 7+15 and named Glu-B1-XII in 95; however, the earlier name, Glu-B1-IX (1117), has precedence. Also, 1117 states that the Glu-B1-IX subunit of faster mobility is slightly slower than subunit 15. Subunit 11 of Glu-B1s (7+11) was so numbered in 327 because its mobility is the same as one of the subunits encoded by a Glu-D1 allele (2+11) described in 545.
Fifteen combinations involving 12 HMW subunits [1B (a-o)] are listed in 290. Eight alleles at Glu-B1-1 and 10 alleles at Glu-B1-2 were described in T. turgidum var. dicoccoides populations (579).
