CC -!- PATHWAY: Plant hormone biosynthesis; gibberellin biosynthesis.
CC {ECO:0000269|PubMed:16181493}.
CC -!- TISSUE SPECIFICITY: Expressed in siliques and in seeds, specifically at
CC the rim of the embryo and the outer integument. Also expressed in
CC flowers. Not detected in roots, stems and leaves.
CC {ECO:0000269|PubMed:15927942, ECO:0000269|PubMed:16460513,
CC ECO:0000269|PubMed:17277098}.
CC -!- DEVELOPMENTAL STAGE: Expressed in developing siliques 3-13 days after
CC pollination. {ECO:0000269|PubMed:15927942}.
