Chloroplast and mitochondrial genomes of Balbiania investiens (Balbianiales, Nemaliophycidae)

Abstract

The Balbianiales is one of only three strictly freshwater orders in the red algal subclass Nemaliophycidae. To date, organellar genomes for one of the 11 orders have been reported, including the other two strictly freshwater orders. There are no organellar genome data from Balbianiales and these data will better enable evolutionary studies of red algal plastids. We performed high-throughput sequencing to assemble and annotate organellar genomes of Balbiania investiens. The 186,778 bp plastid genome encodes 199 protein-coding genes, six rRNAs, 33 tRNAs, one ncRNA, and one tmRNA. Notable losses from the plastid genome included genes involved with the LIPOR enzyme, highly conserved group II int..
