Somatic inactivation and reactivation of Ac associated with changes in cytosine methylation and transposase expression.

Genetics - 1 Sept 1994

Brutnell T P, Dellaporta S L

Abstract excerpt

Several metastable Ac alleles at the maize p locus were identified that produced novel pericarp variegation patterns. From the transmission analysis of pericarp sectors, we show that Ac inactivation is a somatic process. Ac excision from P and transactivation of an unlinked Ds was delayed or absent in plants with metastable Ac alleles. These decreases in Ac activity were correlated to increases in cytosine...
