Expression of β-Galactosidase Gene in Pollen of ,,plants, the anthers shed pollen half of which is (β-galactosidase deficient. The cytochemical test for enzyme activity involved incubation of the pollen in an artificial cytochemical substrate, 5-bromo-4-chloro-3-indoxyl β-galactoside (Singh and Knox, 1984). Genetic studies of the inheritance of the
