A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Characterization of Phytoene Desaturase Knockout Carotenoid‐Deficient Microalgal Mutants Generated by Cas9‐Ribonucleoprotein Complexes

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Phytoene desaturase (PDS; EC 1.3.5.5) is a key enzyme of the carotenoid biosynthetic pathway, catalyzing the desaturation of phytoene, precursor of all carotenoids. In this study, several PDS‐knockout (PDS‐KO) transformants of the chlorophyte microalga Chlamydomonas reinhardtii were generated using a reverse genetics strategy. Two single guide

The combined effects of Golden2‐like 2 and Pseudo‐Response Regulator 2 control the fruit pigmentation in pepper

The Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY Fruit pigmentation mainly controlled by chlorophyll, carotenoids, and flavonoids is an important phenomenon for fortifying the nutritional and esthetic value of humans. Our previous study identified Pseudo‐Response Regulator 2 (PRR2) as a regulator of fruit pigmentation through its association with the c1 locus.
