Transcribed enhancer sequences are required for maize p1 paramutation.

Genetics - 3 Jan 2024

Sidorenko Lyudmila V, Chandler Vicki L, Wang Xiujuan, Peterson Thomas

Abstract excerpt

Paramutation is a transfer of heritable silencing states between interacting endogenous alleles or between endogenous alleles and homologous transgenes. Prior results demonstrated that paramutation occurs at the P1-rr (red pericarp and red cob) allele of the maize p1 (pericarp color 1) gene when exposed to a transgene containing a 1.2-kb enhancer fragment (P1.2) of P1-rr. The paramutable P1-rr allele undergoes...
