From Robert J. Spreitzer, University of Nebraska, August 2014

Using standard methods of directed mutagenesis and nuclear-gene transformation of rbcS∆-T60-3 mt- (CC-4690) (Genkov and Spreitzer 2009), Todor Genkov in Spreitzer’s group created an L66G substitution (CTG-GGC) in the Rubisco small subunit. This mutant was created to see whether an L66G substitution in the nuclear-encoded small subunit could suppress the biochemical defects that arise from an L290F substitution in the chloroplast-encoded large subunit (Chen et al. 1988). The L66G substitution increases the thermal stability of wild-type Rubisco (Genkov and Spreitzer, unpublished). This strain has been maintained with acetate medium in darkness since its creation.
