Progressive loss of DNA methylation releases epigenetic gene silencing from a tandemly repeated maize Myb gene.

Genetics - 1 Jan 2009

Sekhon Rajandeep S, Chopra Surinder

Abstract excerpt

Maize pericarp color1 (p1) gene, which regulates phlobaphene biosynthesis in kernel pericarp and cob glumes, offers an excellent genetic system to study tissue-specific gene regulation. A multicopy p1 allele, P1-wr (white pericarp/red cob) is epigenetically regulated. Hypomethylation of P1-wr in the presence of Unstable factor for orange1 (Ufo1), leads to ectopic pigmentation of pericarp and other organs. The...
