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.

Strigolactone Levels in Dicot Roots Are Determined by an Ancestral Symbiosis-Regulated Clade of the PHYTOENE SYNTHASE Gene Family. [PDF]
Front Plant Sci, 2018 Strigolactones (SLs) are apocarotenoid phytohormones synthesized from carotenoid precursors. They are produced most abundantly in roots for exudation into the rhizosphere to cope with mineral nutrient starvation through support of root symbionts ...

A single gene for lycopene cyclase, phytoene synthase, and regulation of carotene biosynthesis in Phycomyces [PDF]
, 2001 Previous complementation and mapping of mutations that change the usual yellow color of the Zygomycete Phycomyces blakesleea- nus to white or red led to the definition of two structural genes for carotene biosynthesis.
