Electrophoretic mobility; null allele is known; cytosolic; dimeric; intralocus hybrid bands occur; cDNA clone pGPI1a (Lal & Sachs, 1995). Low copy number in Southerns with cDNA probe. Polymorphisms probed by pGPI1a may show recombination with the isozyme polymorphism; the two sites have been subsumed under the gene name. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
