Complete chloroplast genomes of the Chlamydomonas reinhardtii nonphotosynthetic mutants CC-1375, CC-373, CC-4199, CC-2359 and CC-1051

AbstractThe chloroplast genomes (cpDNA) of five Chlamydomonas reinhardtii nonphotosynthetic mutants were sequenced. The architecture, gene content, and synteny of the cpDNAs from the five mutants are identical to the C. reinhardtii ‘wild-type’ plastome. A small number of differences at sequence level between coding regions of the reference genome and the cpDNAs of the mutants were detected. The vast majority of the sequence differences were synonymous and likely due to nucleotide substitutions preceding the generation of the mutant strains, but not caused by the erosion of the cpDNA following the loss of photosynthesis.
