MATERNALLY EXPRESSED PAB C-TERMINAL, a novel imprinted gene in Arabidopsis, encodes the conserved C-terminal domain of polyadenylate binding proteins.

Parental imprinting is important for seed development, but few imprinted genes have been identified in plants. The four known imprinted genes in Arabidopsis thaliana encode transcriptional regulators. Here, we describe a novel imprinted gene, MATERNALLY EXPRESSED PAB C-TERMINAL (MPC), which encodes the C-terminal domain of poly(A) binding proteins (PABPs).
