RT   during soybean (Glycine max L.) somatic embryo development.";
RL   Plant Mol. Biol. 24:465-473(1994).
CC   -!- FUNCTION: Possible transcription activator involved in early embryonic
CC       development. Probably binds to the DNA sequence 5'-TGAC-3'.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Expressed mainly in embryonic tissues. Weakly
CC       detected in stems and hypocotyl.
CC   -!- DEVELOPMENTAL STAGE: First expressed in the embryo proliferation stage,
CC       increases during early somatic embryo development and decreases
CC       thereafter.
CC   -!- SIMILARITY: Belongs to the TALE/KNOX homeobox family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00559}.
