Complete chloroplast genome of the diatom Skeletonema pseudocostatum from the Western Mediterranean coast of Algeria

We sequenced the chloroplast genome of Skeletonema pseudocostatum clone SZCZ 1832 from Algeria. The genome is 127,013 bp long. The inverted repeat region is 18,240 bp long and the order of the genes it encodes appeared as highly conserved when compared with other Thalassiosirales. The maximum likelihood phylogeny also evidenced the belonging of S. pseudocostatum within the Thalassiosirales. This chloroplastic genome is so far the first made available for the cosmopolitan and ecologically important genus Skeletonema.
