CC   -!- FUNCTION: Putative 3'-5' exonuclease degrading single-stranded small
CC       RNAs.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- DISRUPTION PHENOTYPE: Plants do not show a phenotype alteration due to
CC       the redundancy with other SDN ribonucleases.
CC       {ECO:0000269|PubMed:18787168}.
CC   -!- SIMILARITY: Belongs to the REXO1/REXO3 family. {ECO:0000305}.
