Description (was prot1) electrophoretic mobility, null allele is known; embryo protein; SSRs phi011, 055, 094. Embryo protein mobility variations. Depending on allele, encodes an embryo-specific storage protein of molecular weight 60,000 to 70,000 (Khavkin et al. 1978 Planta 143:11; Schwartz 1979 MGG 174:233; Kriz and Schwartz 1986 Plt Phys 82:1069). This saline-soluble, water-soluble protein is similar to the 7S (vicilin) class of seed proteins predominant in dicots. The gene is highly polymorphic, and several variants have been described, including the electrophoretic size alleles Glb1-L (Large protein), Glb1-S (Small protein), Glb1-V (Variant) (Osterman 1988 Biochem Gen 26:463; Kriz et al. 1992 MNL66:109) and the null allele Glb1-0, which produces no protein. Published nucleotide sequences include that of a Glb1-S cDNA clone (Belanger and Kriz 1989 Plant Phys 91:636) and genomic clones corresponding to Glb1-L, Glb1-S, and Glb1-0 (Belanger and Kriz 1991 Genetics 129:863). The glb1 gene is positively regulated by abscisic acid, ABA, and appears to require both ABA and a functional Vp1 gene product for expression (Kriz et al. 1990 Plant Phys 92:; Rivin and Grudt 1991 Plant Phys 95:973). (A. Kriz and E. Khavkin). SSR probe p-phi011 was derived from sequence for glb1, but is shown in MNL 69 on chromosome 6 in error. This primed sequence is not polymorphic in B73 x Mo17, but maps in Mo17 x H99 RIs on 1L in the same bin as glb1, at the same location as phi055 (L. Senior email to EHC 3 May 96). Intron(s). This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
