== Function ==
[https://www.uniprot.org/uniprot/AB25G_ARATH AB25G_ARATH] High affinity abscisic acid (ABA) transporter that mediates the export of ABA, with a preference for (+)-ABA, through the plasma membrane, especially in vascular tissues (e.g. phloem companion cells), and is involved in the intercellular ABA signaling pathway (PubMed:20133881, PubMed:20935463, PubMed:24521878, PubMed:26517905). Together with ABCG31, export ABA from the endosperm to deliver it to the embryo via ABCG30 and ABCG40-mediated import to suppress radicle extension and subsequent embryonic growth (PubMed:26334616).<ref>PMID:20133881</ref> <ref>PMID:24521878</ref> <ref>PMID:26334616</ref> <ref>PMID:20935463</ref> <ref>PMID:26517905</ref>
