Excision patterns of Activator (Ac) and Dissociation (Ds) elements in Zea mays L.: implications for the regulation of transposition.

Genetics - 1 Dec 1996

Heinlein M

Abstract excerpt

The pattern of aleurone variegation of maize kernels carrying Ac and bz-m2(DI) as reporter allele for Ac activity depends on the dosage of both Ac and Ds. Alterations of Ac dosage can abolish Ds excision at certain times and allow it to occur at other times. wx-m7 and wx-m9 are different Ac insertions in the Waxy gene which have different dosage effects on Ds excision. Kernels, heterozygous for the two Ac alleles...
