The chloroplast and mitochondrial genomes of the green algae Pediastrum duplex isolated from Central Georgia (USA)

A Pediastrum duplex (Chlorophyta) strain was isolated from a freshwater system in Milledgeville, Georgia and its chloroplast and mitochondrial genomes sequenced. The chloroplast genome was 199,241 bp with 136 genes and the mitochondrial 40,756 bp with 40 genes, both were circular. Comparison of the ‘Milledgeville’ plastome to other P. duplex isolates revealed a nearly identical sequence identity to archived genes and genomic fragments from the strain UTEX1364 which was isolated from Lake Machovo in 1962. These sequences provide chloroplast and mitochondrial genomes from a wild P. duplex isolate and provide more organelle genomes for a genus with cryptic phylogenetic relationships
