Maize Unstable factor for orange1 Is Required for Maintaining Silencing Associated with Paramutation at the pericarp color1 and booster1 Loci
A. Pericarp and cob glume pigmentation phenotypes of F1 progeny obtained from a cross between P1-prTP and p1-ww Ufo1-1 plants. B. Heritability of Ufo1-1-induced reactivation of P1-prTP. F1 plants showing gain of pericarp pigmentation (red/variegated pericarps) were crossed with p1-ww[4Co63] and test-cross progenies were examined for pericarp and cob glume pigmentation. Expected segregation frequencies are based on assumption that increased pigmentation of P1-prTP allele is not heritable in the absence Ufo1-1.
