A specific beta-glucosidase-aggregating factor is responsible for the beta-glucosidase null phenotype in maize.

Abstract excerpt

Maize (Zea mays L.) beta-glucosidase was extracted from shoots of a wild-type (K55) and a "null" (H95) maize genotype. Enzyme activity assays and electrophoretic data showed that extracts from the null genotype had about 10% of the activity present in the normal genotype. Zymograms of the null genotype were devoid of any activity bands in the resolving gel, but had a smeared zone of activity in the stacking gel...
