We report the complete chloroplast genome of the MED1 strain of Nephroselmis pyriformis from the
Eastern Mediterranean Sea. At 111,026 bp, this genome is smaller and more compact than those of
Nephroselmis olivacea and Nephroselmis astigmatica, and in contrast to the latter taxa, its inverted
repeat contains no complete protein-coding genes. It encodes 3 rRNAs, 33 tRNAs and 94 proteins.
Maximum likelihood analysis of a concatenated set of chloroplast genes from green algae belonging to
deep-diverging lineages positioned the three Nephroselmis species in a strongly supported clade in
which N. pyriformis is sister to N. astigmatica.
