The complete chloroplast genome of Phaeodactylum tricornutum ICE-H isolated from the Antarctic sea ice

Abstract

Phaeodactylum tricornutum ICE-H is a single-cell eukaryotic alga that can grow in the extreme Antarctic environment. The complete chloroplast genome of Phaeodactylum tricornutum ICE-H was assembled with the Illumina sequencing. The chloroplast genome was 117,363 bp in size, containing a large single-copy region (LSC, 63,668 bp), a small single-copy region (SSC, 39,871 bp), and a pair of inverted repeat regions (IRs, 13,824 bp each). The overall GC content was 32.15%. A total of 168 genes were predicted including 132 protein-coding genes, 30 tRNAs, and 6 rRNAs. Phylogenetic analysis indicated that Phaeodactylum tricornutum ICE-H was closely related to Didymosphenia geminata.
