Complete Chloroplast Genome of an Endophytic Ostreobium sp. (Ostreobiaceae) from the U.S. Virgin Islands

Abstract

We present the complete chloroplast genome sequence of an endophytic Ostreobium sp. isolated from a 19th-century coralline red algal specimen from St. Croix, U.S. Virgin Islands. The chloroplast genome is 84,848 bp in length, contains 114 genes, and has a high level of gene synteny to other Ostreobiaceae.

FIG 1

Complete chloroplast genome of Ostreobium sp. The genome was annotated using GeSeq (12), NCBI ORFfinder, and Sequin 15.5 (13), and mapped with Chloroplot 0.2.4 (14). The center contains genome characteristics. The innermost ring shows the genome length. The second ring displays the GC content and direction of transcription, as indicated by the two arrows. The final ring shows the genes. Genes transcribed clockwise are on the inside; counterclockwise transcriptions are on the outside. The color coding corresponds to genes of different groups as listed in the key in the bottom left. CDS, coding sequences.
