Application of 5-aminolevulinic acid promotes ripening and accumulation of primary and secondary metabolites in postharvest tomato fruit

Frontiers in Nutrition, 2022
5-Aminolevulinic acid (ALA) plays a vital role in promoting plant growth, enhancing stress resistance, and improving fruit yield and quality. In the present study, tomato fruits were harvested at mature green stage and sprayed with 200 mg L–1 ALA on ...

Functional analysis of the Phycomyces carRA gene encoding the enzymes phytoene synthase and lycopene cyclase. [PDF]

PLoS ONE, 2011
Phycomyces carRA gene encodes a protein with two domains. Domain R is characterized by red carR mutants that accumulate lycopene. Domain A is characterized by white carA mutants that do not accumulate significant amounts of carotenoids. The carRA-encoded

Stereoisomers of Colourless Carotenoids from the Marine Microalga Dunaliella salina

Molecules, 2020
Carotenoids comprise a diverse range of naturally occurring stereoisomers, which differ in their physico-chemical properties. Their biosynthesis begins with phytoene, which is a rarity among carotenoids because it is colourless.
