The complete chloroplast genome of Pterospermum menglunense (Sterculiaceae), an endangered species.

ABSTRACT: Pterospermum menglunense is the endangered plant species of the genus Pterospermum in the family Sterculiaceae. In the study, the complete genome was 162,421bp in length, including of two inverted repeats (IRA and IRB, 25,572 bp), separated by a large single-copy region (LSC, 90,754 bp) and a small single-copy region (SSC, 20,523 bp). The genome annotation reveals a total of 132 genes, including 37 transfer RNA (tRNA) genes, 8 ribosomal RNA (rRNA) genes, and 87 protein-coding (PCG) genes. The phylogenetic tree showed P. menglunense is closely related to Pterospermum kingtungense.

Complete chloroplast genome sequences of two endangered Phoebe (Lauraceae) species.

Project description:BACKGROUND:Phoebe (Lauraceae) comprises of evergreen trees or shrubs with approximately 100 species, distributed in tropical and subtropical Asia and Neotropical America. A total of 34 species and three varieties occur in China. Despite of economic and ecological value, only limited genomic resources are available for this genus. RESULTS:We sequenced the two complete chloroplast (cp) genomes of Phoebe chekiangensis and P. bournei using Illumina sequencing technology via a combined strategy of de novo and reference-guided assembly. We also performed comparative analyses with the cp genomes of P. sheareri and P. sheareri var. oineiensis previously reported. The chloroplast genomes of P. chekiangensis and P. bournei identically contain 112 genes consisting of 78 protein coding genes, 30 tRNA genes, and 4 rRNA genes, with the size of 152,849 and 152,853 bp, respectively. From the two chloroplast genomes, 131 SSRs were identified and 12 different SSRs located in five protein coding genes. The analysis showed the extremely conserved structure of chloroplast genomes with surprisingly little variations at the LSC/IR and SSC/IR boundaries. Moreover, the mean nucleotide diversity was found to be 0.162% for 77 regions, suggesting an extraordinarily low level of sequence divergence. Four highest divergent regions (trnH-psbA, rps14-trnT, petA-psbJ, ccsA-ndhD) with the percentage of nucleotide diversity higher than 0.50% were identified, which had potential use for species identification and phylogenetic studies. CONCLUSION:This study will facilitate our understanding of population genetics, phylogenetic relationship and plant evolution of Phoebe species.

The complete chloroplast genome of the endangered species Cephalotaxus hainanensis (Cephalotaxaceae).

Project description:Cephalotaxus hainanensis is an endangered tree endemic to China with high medicinal values. In this study, the complete chloroplast genome of C. hainanensis was de novo assembled using Illumina high-throughput sequencing technology. The whole chloroplast genome was 136,877?bp long with an asymmetric base composition (32.6% A, 17.6% C, 17.4% G and 32.4% T). The genome annotation predicted a total of 114 genes, including 82 protein-coding genes, 28 tRNA genes, and four rRNA genes. The neighbour-joining phylogenetic analysis based on 41 complete chloroplast genome sequences showed that C. hainanensis was more closely related to the congeneric C. sinensis. The assembled chloroplast genome of C. hainanensis will provide useful genomic data both for the phylogenetic research of Cephalotaxus and the conservation of this endangered species.
