摘要: The RRM-domain proteins FCA and FPA have previously been characterized as flowering-time regulators in Arabidopsis. We show that they are required for RNA-mediated chromatin silencing of a range loci the genome. At some target loci, promote asymmetric DNA methylation, whereas at others function parallel to methylation. Female gametophytic development early embryonic particularly susceptible malfunctions FPA. propose regulate single low-copy genes interact locus-dependent manner with canonical small interfering RNA-directed methylation pathway common targets.
