The complete mitochondrial genome of an endangered mangrove plant: Scyphiphora hydrophyllacea

Abstract

The complete mitochondrial genome of an endangered mangrove plant: Scyphiphora hydrophyllacea was analyzed in this paper, which is the first for the genus within the family Rubiaceae. The mitogenome sequence is 354,155 bp in length containing 3 ribosomal RNA genes, 16 transfer RNA genes, and 37 protein-coding genes. Gene ccmFc, ccmFn, rps3, rps13, rps10, rpl12, nad3 and cox1 contain one intron, gene cox2 and atp9 contain three introns and gene nad1, nad4 and nad7 contain four introns. Furthermore, Gene nad2 and nad5 have five introns. Gene nad1, nad2, nad5, nad7and Cox2 are trans-splicing genes. Phylogenetic analysis using the maximum likelihood method positioned S. hydrophyllacea closely with Asclepias syriaca in Gentianales.
