The complete chloroplast genome sequences of Trapa quadrispinosa and T. bicornis var. taiwanensis

The complete chloroplast genomes of Trapa quadrispinosa and T. bicornis var. taiwanensis were reported in this study. The chloroplast genome of T. quadrispinosa was 155,554bp in length, containing an LSC of 88,506bp, an SSC of 18,274bp, and a pair of IR regions of 24,387bp each. The chloroplast genome of T. bicornis var. taiwanensis was 155,543bp in length, including an LSC of 88,497bp, an SSC of 18,274bp, and a pair of IR regions of 24,386bp each. Both genomes had 112 genes, consisting of 78 protein-coding genes, 30 tRNA genes, and four rRNA genes. The phylogenetic analysis revealed that the family Trapaceae was closely related to the family Sonneratiaceae.本研究报道了四角菱（Trapa quadrispinosa）及台湾菱（Trapa bicornis var. taiwanensis）的完整叶绿体基因组。四角菱的叶绿体基因组全长为155554 bp，包含长单拷贝区（Large Single Copy, LSC）88506 bp、短单拷贝区（Small Single Copy, SSC）18274 bp以及一对反向重复区（Inverted Repeat, IR），每个区域长度为24387 bp。台湾菱的叶绿体基因组全长为155543 bp，包含长单拷贝区88497 bp、短单拷贝区18274 bp以及一对反向重复区，每个区域长度为24386 bp。两个叶绿体基因组均包含112个基因，其中包括78个蛋白编码基因、30个转运RNA（transfer RNA, tRNA）基因以及4个核糖体RNA（ribosomal RNA, rRNA）基因。系统发育分析结果表明，菱科（Trapaceae）与海桑科（Sonneratiaceae）亲缘关系密切。
