Combination of CG methylation and Chromomethylase 2-mediated RdDM-independent CHH methylation is required for chromosome-specific rRNA gene silencing

2023-02-04

Abstract excerpt

Arabidopsis thaliana has two nucleolus organizer regions (NORs), consisting of long tandem arrays of 45S rRNA genes on chromosomes 2 ( NOR2 ) and 4 ( NOR4 ). The rRNA gene subtypes mapping to NOR2 are mostly silenced during development, whereas most of those mapping to NOR4 are active. Cytosine methylation of promoters plays a significant role in rRNA gene silencing, but recent findings demonstrate that gene b...
