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
