CC   -!- FUNCTION: Probably binds to the DNA sequence 5'-TGAC-3'.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Strongly expressed in ear inflorescence primordia
CC       and shoot meristem. Weakly expressed in embryos. Absent from leaves.
CC   -!- SIMILARITY: Belongs to the TALE/KNOX homeobox family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00559}.
