ABSCISIC ACID-DEFICIENT4 Has an Essential Function in Both cis-Violaxanthin and cis-Neoxanthin Synthesis
Year: 2020
Type: article
Abstract: increases both 9-cis-violaxanthin and ABA accumulation. Subcellular localization of NXD1 protein in transient expression assays suggests that production of the NXD1-derived factor required for neoxanthin synthesis takes place in the cytosol. Finally, we postulate that ABA4, with additional unknown cofactor(s), is required for, or contributes to, trans-to-cis violaxanthin isomerase activity, producing both cis-xanthophyll precursors of ABA.
