Dof zinc finger protein DOF3.7

Gene

DOF3.7

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

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 inactivity of a component that would be activated to trigger germination as a consequence of red light perception.

Miscellaneous

The regulatory role of DOF3.7/DAG1 appears to be opposite to that of DOF2.5/DAG2. Both zinc finger proteins may act on a maternal switch that controls seed germination, possibly by regulating the same gene(s).

Expressioni

Tissue specificityi

Expressed in the phloem of the mother plant, including in roots, stem, leaves and flowers, 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.

Developmental stagei

Turned off in siliques when they reached full maturation. Not expressed in developing or mature embryos.
