A partial list of previously undescribed maternally expressed imprinted genes at a P < 0.001 (except #). Total maternal (M) and paternal (P) reads are shown for the indicated genotypes as well as transcriptional scores (number of reads per kilobase of sequence per 10 million aligned reads) for endosperm (Endo exp), embryo (Emb exp), and the indicated mutant genotypes. #, identified by Sanger sequencing; m, biallelic in met1 endosperm; d, down-regulated in dme endosperm; f, down-regulated in fie endosperm; TF, transcription factor.
*Transcriptional scores derived from manually dissected and LCM tissue are shown before and after the slash, respectively.
