Targeted mutagenesis using CRISPR-Cas9 in the chelicerate herbivore Tetranychus urticae [PDF]
, 2020 The use of CRISPR-Cas9 has revolutionized functional genetic work in many organisms, including more and more insect species. However, successful gene editing or genetic transformation has not yet been reported for chelicerates, the second largest group ...

Characterization of Phytoene Desaturase Knockout Carotenoid-Deficient Microalgal Mutants Generated by Cas9-Ribonucleoprotein Complexes. [PDF]
Physiol PlantABSTRACT 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

A new F131V mutation in Chlamydomonas phytoene desaturase locates a cluster of norflurazon resistance mutations near the FAD-binding site in 3D protein models. [PDF]
PLoS ONE, 2014 The green alga Chlamydomonas reinhardtii provides a tractable genetic model to study herbicide mode of action using forward genetics. The herbicide norflurazon inhibits phytoene desaturase, which is required for carotenoid synthesis.
