Tandem gene duplications drive divergent evolution of caffeine and crocin biosynthetic pathways in plants

BMC Biology, 2020
Background Plants have evolved a panoply of specialized metabolites that increase their environmental fitness. Two examples are caffeine, a purine psychotropic alkaloid, and crocins, a group of glycosylated apocarotenoid pigments.

Multi-species transcriptome analyses for the regulation of crocins biosynthesis in Crocus

BMC Genomics, 2019
Background Crocins are soluble apocarotenoids that mainly accumulate in the stigma tissue of Crocus sativus and provide the characteristic red color to saffron spice, in addition to being responsible for many of the medicinal properties of saffron ...

Mediating oxidative stress enhances α-ionone biosynthesis and strain robustness during process scaling up

Microbial Cell Factories, 2022
Background α-Ionone is highly valued in cosmetics and perfumery with a global usage of 100–1000 tons per year. Metabolic engineering by microbial fermentation offers a promising way to produce natural (R)-α-ionone in a cost-effective manner.

Key Residues for Catalytic Function and Metal Coordination in a Carotenoid Cleavage Dioxygenase [PDF]

Journal of Biological Chemistry, 2016
Carotenoid cleavage dioxygenases (CCDs) are non-heme iron-containing enzymes found in all domains of life that generate biologically important apocarotenoids. Prior studies have revealed a critical role for a conserved 4-His motif in forming the CCD iron center.

Identification and Characterization of CCD Gene Family in Rose (Rosa chinensis Jacq. ‘Old Blush’) and Gene Co-Expression Network in Biosynthesis of Flower Scent

Horticulturae, 2023
Rose (Rosa sp.) is a widely used raw material for essential oil extraction and fragrance production. The carotenoid cleavage dioxygenases pathway is one of the main metabolic pathways for the degradation of carotenoids, which is located downstream of the

Carotenoids in staple cereals: Metabolism, regulation, and genetic manipulation

Frontiers in Plant Science, 2016
Carotenoids play a critical role in animal and human health. Animals and humans are unable to synthesize carotenoids de novo, and therefore rely upon diet as sources of these compounds.

The role of strigolactones in P deficiency induced transcriptional changes in tomato roots

BMC Plant Biology, 2021
Background Phosphorus (P) is an essential macronutrient for plant growth and development. Upon P shortage, plant responds with massive reprogramming of transcription, the Phosphate Starvation Response (PSR). In parallel, the production of strigolactones (
