From Robert J. Spreitzer, University of Nebraska, November 2014
Using standard methods of directed mutagenesis and chloroplast transformation of rbcL∆-MX3312 mt+ (CC-4696) (Satagopan and Spreitzer 2004), Boon Hoe Lim in Spreitzer’s group created two substitutions (V149Q and I282H) together in the Rubisco large subunit. This mutant (also named G149-282) represents one of 15 “groups” of amino acids that differ between Chlamydomonas and land plants (Du et al. 2003). It was created to investigate phylogenetic differences that influence Rubisco catalysis (Spreitzer et al. 2005). This strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function.

Phenotype: requires acetate, sensitive to light, spectinomycin resistant
This Rubisco rbcL knock-out mutant was created by Boon Hoe Lim in Spreitzer’s group by using aadA to replace chloroplast rbcL of rbcL-Penta/rbcS1-ABSO mt+ (CC-4848) (Spreitzer et al. 2005). The mutant lacks Rubisco large subunits, but is capable of expressing the ABSO small subunit, which was previously engineered by replacing the Chlamydomonas betaA-betaB loop with the loop from the small subunit of spinach Rubisco (Karkehabadi et al. 2005; Spreitzer et al. 2005). The mutant was created to investigate large-subunit amino acids that differ between Chlamydomonas and land plants, and that interact with small-subunit amino acids (Du et al. 2003). This strain has been cloned to homoplasmicity, and maintained with acetate medium in darkness since its isolation.

Using standard methods of directed mutagenesis and chloroplast transformation of rbcL∆-MX3312 mt+ (CC-4696) (Satagopan and Spreitzer 2004), Boon Hoe Lim in Spreitzer’s group created 12 substitutions (G168P, R305K, L326I, V341I, M349L, M375L, A398S, C399V, D470E, T471A, I472M, and K474T) together in the Rubisco large subunit. This mutant (also named AG341) represents one of 15 “associated groups” of amino acids that differ between Chlamydomonas and land plants (Du et al. 2003). It was created to investigate phylogenetic differences that influence Rubisco catalysis (Spreitzer et al. 2005). The mutant strain has a small decrease in Rubisco holoenzyme (Lim and Spreitzer, unpublished). It has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function.

Phenotype: requires acetate, sensitive to light
Using plasmid p699 (GuhaMajumdar et al. 2008), Boon Hoe Lim in Spreitzer’s group performed rbcL direct mutagenesis, chloroplast transformation of wild-type 2137 mt+ (CC-4887), selection for spectinomycin resistance in the dark, and screening for a homoplasmic acetate-requiring phenotype to create 34 substitutions together in the Rubisco large subunit (A11V, V30E, V31T, R32K, M42V, C53A, D86H, I105L, V149Q, G168P, V221C, V235I, C256F, K258R, I265V, I282H, R305K, L326I, V341I, M349L, C369V, M375L, V391T, A398S, C399V, T428V, G442N, D443E, V444I, S447E, D470E, T471A, I472M, and K474T). The mutant lacks Rubisco holoenzyme (Lim and Spreitzer, unpublished). It was created to investigate phylogenetic differences that influence Rubisco catalysis (Du et al. 2003; Spreitzer et al. 2005). This strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function or suppress light sensitivity (Spreitzer and Ogren 1983).

Using standard methods of directed mutagenesis and chloroplast transformation of rbcL∆-MX3312 mt+ (CC-4696) (Satagopan and Spreitzer 2004), Boon Hoe Lim in Spreitzer’s group created three substitutions (V221C, C256F, and K258R) together in the Rubisco large subunit. This mutant was created to investigate the molecular basis for the increased CO2/O2 specificity of mutant rbcL-Penta/rbcS1-ABSO mt+ (CC-4848) (Spreitzer et al. 2005). This strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function.
