CC -!- FUNCTION: Probable transcription factor that regulates carpel
CC integuments formation. Required for the specification of polarity in
CC the ovule inner integument. Modulates the content of flavonols and
CC proanthocyanidin in seeds. {ECO:0000269|PubMed:16623911,
CC ECO:0000269|PubMed:19054366, ECO:0000269|PubMed:20444210}.

CC Name=1;
CC IsoId=Q9FJV5-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9FJV5-2; Sequence=VSP_041078, VSP_041079;
CC -!- TISSUE SPECIFICITY: Expressed in the periphery of the primary root apex
CC and lateral root. {ECO:0000269|PubMed:15286295}.
CC -!- DEVELOPMENTAL STAGE: During ovule development, first expressed in the
CC inner integument primordium and then on the abaxial side of the inner
CC integument. {ECO:0000269|PubMed:16623911}.
CC -!- DISRUPTION PHENOTYPE: Ovules with a single integument instead of two.
CC {ECO:0000269|PubMed:16623911}.
CC -!- MISCELLANEOUS: Plants overexpressing KAN4 show reduced or absent ovule
CC outer integument and color alteration of the seed coat.
