    Overall Conclusion

    Blastx results show a few matches to hypotethical proteins in rice, sorghum, and other plants. The matches are overall fairly weak, the strongest match has a E.value of 10^-30. No matches to common domains or motifs were found.

    Blastx of the whole ~3kb region predicted by FGeneSH produces similar results in all ORFs so the lack of protein support is likely not due to a grossly incorrect model. Blastp of the FGeneSh predicted protein sequence (FGeneSH model not vastly different than our proposed model) did not return any results.

    Given the strong support of the model and overall expression of this region and lack of protein support it is possible that the region is a maybe coding for an ncRNA of some sort. The possibility also exists that there has not been work to characterize the encoded protein transcribed from this region.
