Transcription factor specifically involved in the maternal control of seed germination. Regulates transcription by binding to a 5'-AA[AG]G-3' consensus core sequence. May ensure the activation of a component that would trigger germination as a consequence of red light perception. Expressed in the vascular system of the mother plant, but not present in the seed and embryo. In maturing siliques, found all through the funiculus connecting the placenta to the ovule, but not in the ovule. Turned off in siliques when they reached full maturation. Not expressed in developing or mature embryos. The regulatory role of DOF2.5/DAG2 appears to be opposite to that of DOF3.7/DAG1. Both zinc finger proteins may act on a maternal switch that controls seed germination, possibly by regulating the same gene(s). May be due to an intron retention.
