Involved in the oxidative degradation of abscisic acid, especially in pollinated ovaries. 2-cis-(+)-abscisate + O2 + reduced [NADPH--hemoprotein reductase] = (+)-8'-hydroxyabscisate + H(+) + H2O + oxidized [NADPH--hemoprotein reductase] Plant hormone degradation; abscisic acid degradation. Expressed in ovaries (specifically in ovules and placenta), sepals, petals and pedicels. In unpollinated ovaries, present in the placenta, but not in ovules and pericarp. In pollinated ovaries, accumulates mostly in the placenta and ovules and, at low levels, in the pericarp. Accumulates strongly after pollination in whole ovaries. Induced by auxin (4-Cl-IAA) treatment and abscisic acid (ABA) (PubMed:19322584). First transiently repressed (1 day after treatment) and later induced (2 days after treatment) by abscisic acid (ABA) and dehydration (PubMed:25039074). Belongs to the cytochrome P450 family.
