Function In higher plants aldehyde oxidases (AO) appear to be homo- and heterodimeric assemblies of AO subunits with probably different physiological functions. AO-delta seems to be involved in the last step of abscisic acid biosynthesis, at least in leaves and seeds. In vitro, AO-delta oxidizes abscisic aldehyde to abscisic acid (ABA). In vitro, AO-delta also uses indole-3- aldehyde (IAld), benzaldehyde, 1-naphthaldehyde and cinnamaldehyde as substrate; the AAO2-AAO3 dimer also uses abscisic aldehyde as substrate. {ECO:0000269|PubMed:10972874, ECO:0000269|PubMed:11050171, ECO:0000269|PubMed:15122034, ECO:0000269|PubMed:15574845, ECO:0000269|PubMed:16930325}.
Subcellular Location Cytoplasm {ECO:0000305}.
Tissue Specificity Expressed in vascular tissues of all organs, particularly in phloem companion cells and xylem parenchymatic cells. Highly expressed in roots and rosettes, and to lower extent in seedlings, stems and flowers. Expressed at very low levels in siliques and dry seeds. Also detected in root dividing cells (tips and primordia), in mesophyll cells and inside the guard cells. {ECO:0000269|PubMed:10972874, ECO:0000269|PubMed:11050171, ECO:0000269|PubMed:15064376, ECO:0000269|PubMed:15122034, ECO:0000269|PubMed:15574845, ECO:0000269|PubMed:9489015, ECO:0000269|PubMed:9615466}.
