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

Directed mutagenesis and chloroplast transformation of rbcL-W66Amber mt+ (Spreitzer et al. 1985) were used to create an M42V substitution (ATG-GTA) in the Rubisco large subunit, which causes a small decrease in Rubisco carboxylase activity (Du et al. 2003). This is the original mutant strain. It was created to investigate phylogenetic differences near large-subunit residue Gly-54 (see rbcL-G54D) (Spreitzer et al. 1995). The strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function.
