Transcriptome analysis in tissue sectors with contrasting crocins accumulation provides novel insights into apocarotenoid biosynthesis and regulation during chromoplast biogenesis

Scientific Reports, 2018
Crocins, the red soluble apocarotenoids of saffron, accumulate in the flowers of Crocus species in a developmental and tissue-specific manner. In Crocus sieberi, crocins accumulate in stigmas but also in a distinct yellow tepal sector, which we ...

Optical properties, ethylene production and softening in mango fruit [PDF]

, 2015
Firmness decay, chlorophyll breakdown and carotenoid accumulation, controlled by ethylene, are major ripening events in mango fruit. Pigment content and tissue structure affect the optical properties of the mesocarp, which can be measured ...

Natural allelic variation of basic helix–loop–helix transcription factor 25 regulates carotenoid biosynthesis in sweet potato

Plant Biotechnology Journal, Volume 23, Issue 7, Page 2627-2644, July 2025.
Summary Carotenoid‐rich orange‐fleshed sweet potato (OFSP) is an important staple diet and source of nutrition in developing countries, including Africa and Asia. However, the regulation of carotenoid biosynthesis remains to be better understood. A natural allelic variation closely linked to carotenoid biosynthesis was identified in the promoter region

Combined enhancement of ascorbic acid, β‐carotene and zeaxanthin in gene‐edited lettuce

Plant Biotechnology Journal, Volume 23, Issue 6, Page 1954-1967, June 2025.
Summary Lettuce is widely grown and consumed but provides lower nutritional value compared to other leafy greens, particularly in the essential vitamins A and C. To address this, major control points in carotenoid and ascorbic acid (AsA) production were targeted using a viral‐based CRISPR/Cas9 system in the commercial lettuce cultivar ‘Noga’.

Candidate Gene Analysis Reveals That the Fruit Color Locus C1 Corresponds to PRR2 in Pepper (Capsicum frutescens)

Frontiers in Plant Science, 2020
The diverse fruit colors of peppers (Capsicum spp.) are due to variations in carotenoid composition and content. Mature fruit color in peppers is regulated by three independent loci, C1, C2, and Y.

Impact of High Hydrostatic Pressure and Soaking Solutions on the Surface Structure, Carotenoids, Individuals' Phenolic Acids and Flavonoids Profile of Orange‐Fleshed Sweet Potato Flour

Food Science &Nutrition, Volume 13, Issue 5, May 2025.
High hydrostatic pressure (HHP) and soaking solution modified the properties of orange‐fleshed sweet potato flour (OSPF). Carotenoids in OSPF increased several folds during treatment with ascorbic acid and HHP application at 400 MPa. Ascorbic acid and 400 MPa significantly increased phenolic acids (28.02, 27.40%) and flavonoids (8.45, 63.57 ...

Isolation and functional characterization of Lycopene β-cyclase (CYC-B) promoter from Solanum habrochaites

BMC Plant Biology, 2010
Background Carotenoids are a group of C40 isoprenoid molecules that play diverse biological and ecological roles in plants. Tomato is an important vegetable in human diet and provides the vitamin A precursor β-carotene. Genes encoding enzymes involved in

Structural and functional features of phytoene synthase isoforms PSY1 and PSY2 in pepper Capsicum annuum L. cultivars

Вавиловский журнал генетики и селекции, 2020
The fruits of various pepper cultivars are characterized by a different colour, which is determined by the pigment ratio; carotenoids dominate in ripe fruits, while chlorophylls, in immature fruits.
