The opening of the epoxide ring of violaxanthin generates a chiral allene. Neoxanthin is a precursor of the plant hormone abscisic acid and the last product of carotenoid synthesis in green plants .
high expression level in berries, expression increases markedly at the onset of berry ripening along with the accumulation of abscisic acid. Quantitative real-time PCR enzyme expression analysis during fruit development
plant protoplasts obtained from Arabidopsis thaliana tissue culture and Nicotiana tabacum leaves are transformed with the full length cDNA under control of the 35S CaMV promoter by electroporation and PEG
