Imprinted loci confirmed by RT-PCR and sequencing across SNPs in reciprocal crosses.

1: Mat is maternal and Pat is paternal expression bias.
2: All the loci are imprinted in endosperm and Os10g05750 is also imprinted in the embryo. The gene ID and splice isoform suffix (.1 or .2) relate to the TIGR annotation. Those lacking the isoform suffix are transcripts expressed from an intron.
3: Expression in other plant tissues; g refers to general expression, en refers to endosperm specific expression, and en-p endosperm preferred expression where expression is found to be higher in the endosperm than in other tissues.
4: This indicates the expression of the locus in rice sperm cells using microarray analysis. The data shown in triplicate indicates presence (P), absence (A) or marginal (M) expression in sperm cells following analyses indicated in Materials and Methods.
5: These loci have been predicted to show novel parent of origin-biased alternative splicing. For transcripts arising from Os01g70060, see Figure 2 for summary and Figure S5 for confirmation of parentally biased transcript isoforms.
6: This gene is imprinted in both embryo and endosperm.
