LITERATURE
drastic decline in expression during fruit ripening
ectopic expression of apple F3'H genes contributes to anthocyanin accumulation in the Arabidopsis thaliana transparent testa7-1 mutant tt7 grown under nitrogen stress, overview. Transgenic Arabidopsis tt7 seedlings xpressing apple F3'H regain red color pigmentation and significantly accumulate both 4'-hydroxylated pelargonidin and 3',4'-hydroxylated cyanidin; ectopic expression of apple F3'H genes contributes to anthocyanin accumulation in the Arabidopsis thaliana transparent testa7-1 mutant tt7 grown under nitrogen stress, overview.

enzyme expression is under control of pericarp color1, P1
enzyme is highly expressed in all stages of fruit ripening
expression level increases in response to nitrogen depletion after 12 days of treatment, in agreement with a corresponding increase in 3',4'-catechins, 3',4',5'-catechins and flavan 3-ols content in the leaves
increase at stage of pigmentation initiation
