Project description:Ormosia purpureiflora is endemic to China. It is named after its purple flowers. It is a small tree only up to 3 m. It has leathery leaves, racemose inflorescences. The seeds are elliptic and red in coat. It is only confined to Luofushan Provincial Nature Reserve in Huizhou of Guangdong Province. Herein, we first reported on its complete chloroplast genome sequence as genomic resource for conservation purposes. The chloroplast genome of O. purpureiflora was 173,364 bp in length, with a large single-copy region of 73,465 bp, a small single-copy region of 18,751 bp, and a pair of inverted repeat regions that were 40,574 bp each. A total of 90 protein-coding genes, 38 transfer RNA genes, and eight ribosomal RNA genes were predicted, while 106 simple sequence repeats were recorded throughout the genome. Phylogenetic analysis revealed that O. purpureiflora was sister to O. emarginata.
Project description:Ormosia formosana is an important hardwood species and its seeds are popular as decorative jewelry. Currently, this species is threatened in the natural forests due to habitat destruction. Here, we first report the chloroplast genome of O. formosana for future studies in ecology, phylogeny, and conservation. The chloroplast genome of O. formosana is 173,587 bp in length with a GC content of 35.80%. It includes a large single-copy region of 73,550 bp, a small single-copy region of 18,683 bp, and two inverted repeat regions of 40,696 bp and 40,658 bp, respectively. The genome was totally annotated with 135 genes, including 90 protein-coding genes, eight ribosomal RNA genes, and 37 transfer RNA genes. Phylogenetic analysis indicated that O. formosana is most genetically similar to O. boluoensis.
Project description:Ormosia boluoensis is a critically Endangered species that is exclusively distributed in Xiangtoushan National Nature Reserve in Guangdong province, China. At present, the population of the species is made up of less than 100 adult individuals. Here, we are the first to report the complete chloroplast genome sequence of O. boluoensis. The chloroplast genome of O. boluoensis is 175,760 bp long and includes a large single-copy region that is 74,613 bp, a small, 18,719 bp single copy region and a pair of inverted repeat regions that are 40,771 bp and 41,657 bp in length, respectively. The overall GC content of the O. boluoensis chloroplast genome is 35.58% and contains a total of 134 genes, including 89 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. Phylogenetic analysis revealed that O. boluoensis is genetically similar to O. xylocarpa and O. emarginata genera.
Project description:Cycas ferruginea F. N. Wei (1994) is recorded in the list of wild plant protection in China as a national first-class protected plant. The complete chloroplast genome of C. ferruginea was analyzed for the first time in this article. The genome is 162,045 bp in length, which contains a pair of inverted repeats (IRs) of 25,048 bp each, a large single-copy (LSC) region of 88,827 bp, and a small single-copy (SSC) region of 23,122 bp. The genome comprises a total of 130 encoded genes, including 85 protein-coding genes, eight ribosomal RNA genes, and 37 transfer RNA genes. The total GC content is 39.44%, and the corresponding values of the LSC, SSC, and IRs are 38.73%, 36.56%, and 42.02%, respectively. The phylogenetic relationships were reconstructed based on the complete chloroplast genome sequences of 16 species. Results showed that C. ferruginea is close to C. debaoensis, C. bifida, and C. szechuanensis.
