Genetic analysis of B-Peru, a regulatory gene in maize.

Genetics - 1 Jan 1991

Patterson G I, Harris L J, Walbot V, Chandler V L

Abstract excerpt

The B locus in maize is required for the accumulation of anthocyanin pigments. Numerous B alleles have been described: each determines a particular pattern of pigment synthesis with respect to the tissues that are pigmented and the time during development that pigment synthesis begins. We report...
