CC -!- FUNCTION: Probable transcription factor that plays an important role in
CC building the laminar joint between leaf blade and leaf sheath boundary,
CC thereby controlling ligule and auricle development. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in stems, leaf sheaths, and young
CC panicles. {ECO:0000269|PubMed:16861571}.
CC -!- DOMAIN: The SBP-type zinc finger is required for the binding to DNA.
CC {ECO:0000250}.
CC -!- SEQUENCE CAUTION:
CC Sequence=EAY95872.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
