“…Blue spectrum promoted anthocyanin accumulation in petunia petals, as well as a white spectrum, while red spectrum blocked biosynthesis. According to the authors, the results suggest that the blue spectrum is a key factor for anthocyanins biosynthesis and accumulation (Fu et al, 2020).…”

The lisianthus culture is demanded to produce cut flowers and pot vases, grown in a greenhouse using advanced techniques. The present study aimed to evaluate the pigments of different lisianthus cultivars in different photoselective shade nets. The cultivars Flare Deep Rose (pink), Echo Blue BL (purple) and Allemande White BI (white) were cultivated under light-diffusing polyethylene film cover and blue and red color photoselective nets with a shading capacity of 30%, in addition to the control treatment, without the use of the net. The results showed higher values of chlorophyll b and total in the red photoselective net, independent of the cultivar. Leaf colorimetry showed the most intense shade of green was from the cultivar Echo Blue BL. On the other hand, the control showed more intensity, with no significant difference in the leaf green intensity on the blue and red shade nets. In the petals, the cultivar Echo Blue BL showed a more intense blue shade in the red net, however low grade of anthocyanin than in the blue one. In the anthocyanin pigment, this cultivar had lower levels in the treatment of the red net. The results indicate that the use of photoselective shade nets in the culture of lisianthus changes the content of the pigments studied, in varying intensity, depending on the cultivar.

“…The cryptochrome CRY3 participates in anthocyanin biosynthesis in eggplant, purple broccoli, and petunia. CRY3 expression is repressed in shading conditions and highly induced by light Fields(Li et al ., 2017; Fu et al ., 2020; Liu et al ., 2020). In petunia, while CRY3 was repressed by exposure to red light compared to white and blue lights, CRY1 and CRY2 did not show significant changes in response to the light quality (Fu et al ., 2020).…”

Anthocyanins are specialized plant metabolites with significant dietary value due to their anti-inflammatory properties. Research indicates that dietary intake of these phenolic compounds contributes to preventing various chronic diseases. As the most consumed vegetable worldwide, tomato (Solanum lycopersicum) is an excellent candidate for anthocyanin-enrichment strategies. In tomato, activation of anthocyanin biosynthesis is light-dependent, but this mechanism has yet to be entirely characterized. We investigated the role of light in anthocyanin biosynthesis in fruits of the purple tomato, which is a near-isogenic line (NIL) derived from wild accessions into cv. Micro-Tom (MT). MT-Aft/atv/hp2 starts accumulating anthocyanin early during fruit development but is restricted to the peel (exocarp and epicarp). Manipulating light incidence in different fruit tissues determined that the absence of anthocyanin accumulation in the flesh results from the sun-blocking effect of the cyanic epicarp on the mesocarp, thus preventing light from penetrating deeper into the fruit. Transcriptional analyses of the fruit peel and flesh revealed that the bHLH transcription factor SlAN1 (Solyc09g065100) is the limiting factor for light-dependent anthocyanin accumulation in both tissues. This research enhances our comprehension of the genetic and environmental regulation of anthocyanin accumulation in fruit tissues, offering valuable insights into plant breeding for human nutrition.

“…Generally, pigment type and distribution, petal tissue structure, physical factors including temperature, light and water, and chemical factors, comprising pH value, mineral nutrients and plant hormones, etc. are factors affecting flower color, and among these anthocyanins are the most important flower color determinants [ 3 , 50 – 53 ]. Firstly, functional loss of structural genes usually results in an evolutionary color transition from blue to red or colored to colorless between species, as loss of function is often easier than gain of function [ 54 ].…”

Clivia miniata is renowned for its evergreen and strap-like leaves, whereas its floral color and scent are lacking of diversity. Presently, anthocyanin, volatile terpene and carotenoid metabolisms were integrally investigated in C. miniata flowers. As results, pelargonidins and lutein might cooperate together to confer orange or yellow color to C. miniata flowers, and only trace amount of (+)-limonene was detected. The expression levels of CmF3′H and CmDFR appeared to be responsible for the ratio of cyanidin and pelargonidin derivatives in C. miniata, and the low expression of CmF3′H was responsible for the lack of cyanidins in flowers. Moreover, CmF3′H promoter could not be activated by CmMYBAs, suggesting that it was controlled by novel regulators. Only two CmTPSs were functional with CmTPS2 responsible for (+)-limonene synthesis, contributing to the monotonous flower volatile terpenes of C. miniata. CmCCD1a and CmCCD1b were able to cleave carotenoids at 5, 6 (5′, 6′) and 9, 10 (9′, 10′) positions to generate volatile apocarotenoids, whereas the low-quantified substrates or specific subcellular localizations of CmCCD1s might constrain volatile apocarotenoids release. Consequently, activating F3’H, introducing novel F3’5’H or versatile TPS may be effective ways to modify the floral color and scent, respectively. Alternatively, modifying the carotenoid flux or CCD1 localization might affect floral color and scent simultaneously. As a whole, the present study preliminarily deciphered the genetic constraints underlying flower color, scent developments and proposed possible schemes for further genetic modification of ornamental traits in C. miniata and other plants.
