CC   -!- FUNCTION: Possible transcription activator in response to an external
CC       signal. May be involved in the regulation of flavonoid biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Germinating seed and apical meristem of shoot and
CC       root.
