In roots, expressed in the vascular cylinder within the root apical meristem and only faintly detectable in the differentiated root.DEVELOPMENTAL STAGE:Expressed in young developing stamen primordia and later confined to the central part of growing anthers. Before and during pollination, restricted to the maturing pollen grains.SIMILARITY:Belongs to the oxygen-dependent FAD-linked oxidoreductase family.SEQUENCE CAUTION:Sequence=AAG13068.1; Type=Erroneous gene model prediction; "
