Description Not Available
Transgenic tomato plants accumulating high amounts
(70–100 fold) of anthocyanin in the fruit were developed
by the fruit specific expression of two transcription
factors, Delila and Rosea1 isolated from
Antirrhinum majus. The transgenic tomato plants were
identical to the control plants, except for the accumulation
of high levels of anthocyanin pigments throughout
the fruit during maturity, thus giving the fruit a
purplish colour. The total carotenoids, including lycopene
levels were unaffected in the anthocyanin-rich
fruits, while its antioxidant capacity was elevated. The
gene expression analysis confirmed the elevated expression
of the downstream genes of the anthocyanin
pathway due to the expression of the transcription
factors and the expression levels coincided with the
fruit ripening stages, highest expression occurring
during the breaker stage. Anthocyanin-rich tomato
fruit is important in view of the protective function of
these compounds on consumption against a number of
lifestyle-related diseases.
