Light-induced vegetative anthocyanin pigmentation in Petunia

The Lc petunia system, which displays enhanced, light-induced vegetative pigmentation, was used to investigate how high light affects anthocyanin biosynthesis, and to assess the effects of anthocyanin pigmentation upon photosynthesis. Lc petunia plants displayed intense purple anthocyanin pigmentation throughout the leaves and stems when grown under high-light conditions, yet remain acyanic whe...

Adventitious roots and secondary metabolism.

Plants are a rich source of valuable secondary metabolites and in the recent years plant cell, tissue and organ cultures have been developed as an important alternative sources for the production of these compounds. Adventitious roots have been successfully induced in many plant species and cultured for the production of high value secondary metabolites of pharmaceutical, nutraceutical and indu...

Sunlight-induced anthocyanin pigmentation in maize vegetative tissues

cyanin formation have highlighted that multiple photoreceptors, such as phytochrome, blue/UV-A photoreceptor Although, in maize, sunlight-regulated anthocyanin and UV-B photoreceptor mediate the light action (Beggs formation in vegetative tissues is observed only in the and Wellmann, 1985; Beggs et al., 1986). It is assumed cultivars harbouring homozygous recessive pl loci, the that these photo...

Ethylene suppression of sugar-induced anthocyanin pigmentation in Arabidopsis.

Anthocyanin accumulation is regulated negatively by ethylene signaling and positively by sugar and light signaling. However, the antagonistic interactions underlying these signalings remain to be elucidated fully. We show that ethylene inhibits anthocyanin accumulation induced by sucrose (Suc) and light by suppressing the expression of transcription factors that positively regulate anthocyanin ...
