摘要

The plant science community has almost unanimously accepted that the biosynthesis of (+)-S-ABA occurs by dioxygenase-catalysed cleavage of 9'-cis xanthophylls to yield xanthoxal (Xan), which is oxidized to ABA via AB-aldehyde (Fig. 1). Biochemical, molecular and genetic evidence to support this pathway has recently been reviewed by Adrian Cutler and Joan Krochko. Correctly, the authors highlight the progress that has been made in cloning the genes required for the formation and cleavage of potential xanthophyll precursors. However, a gene that converts carotenoid-cleavage products to ABA has not been identified.
