The complete chloroplast genome sequence of Picea schrenkiana (Pinaceae).

ABSTRACT: Picea is a phylogenetically complicate genus with great economic and ecological values. Here, we determined the whole complete chloroplast genome of Picea schrenkiana to provide genomic information for phylogenetic analysis of the genus. The plastome of P. schrenkiana is 124,060 bp in size and contains 114 genes, including 74 protein-coding genes, 36 tRNA genes, and four rRNA genes. The overall GC content is 38.7%. Unlike the typical plastome with a conserved quadripartite structure, loss of inverted repeat regions is found in the chloroplast genome. The phylogenetic tree shows that monophyly of P. schrenkiana is well supported.

The complete chloroplast genome sequence of Keteleeria hainanensis (Pinaceae).

Project description:Keteleeria hainanensis is an endemic species with extremely narrow distribution. In this study, the complete genome of K._hainanensis was sequenced and analyzed. The genome size is 117,366?bp and it contains two short inverted repeat regions of 1,272?bp, which was separated by a large single-copy (LSC) region of 74,819?bp and a small single-copy (SSC) region of 40,003?bp. The GC content of this genome was 38.57%. The chloroplast genome contained 103 unique genes, including 74 protein-coding gene, 25 tRNA genes, and 4 rRNA gene. Phylogenetic analysis base on 11 chloroplast genomes indicated that K. hainanensis is closely related to K. davidiana.

The complete chloroplast genome sequence of Abies chensiensis (Pinaceae).

Project description:Abies chensiensis is listed as a threatened species in the Red List and categorized as key protected wild plants in China. Here, we determined the complete chloroplast genome of A. chensiensis using the Illumina MiSeq platform. The genome was 121,795 bp in length, comprising a large single copy (LSC) region of 67,160 bp, a small single copy (SSC) region of 54,107 bp, and two inverted repeat regions (IRa and IRb) of 264 bp each. It was composed of 114 genes, including 68 peptide-encoding genes, 35 transfer RNAs (tRNAs), four ribosomal RNAs (rRNAs), six open reading frames and one pseudogene. Phylogenetic analysis revealed that A. chensiensis was most closely related to A. beshanzuensis, with high bootstrap values. The present research will provide potential genetic resources for further conservation and management strategies.

The complete chloroplast genome sequence of Pinus cembra L. (Pinaceae).

Project description:The Swiss pine (Pinus cembra) is a montane tree in Central Europe and, therefore, known for its hardiness against severe winter colds. The seeds are harvested and eaten as pine nuts. We assembled and characterized the complete chloroplast genome of P. cembra to serve as a valuable resource in future genetic studies. The complete plastome sequence is 116,609?bp in length and contains 113 genes including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. A phylogenetic analysis of 34 Pinus plastome sequences shows that Pinus sibirica is the nearest relative to P. cembra and that there is a distinct clustering together with the other members of the section Quinquefoliae.

The complete chloroplast genome sequence of Pinus bhutanica (Pinaceae) and its phylogenetic implications.

Project description:Pinus bhutanica is a critically endangered conifer and occurs only in central Bhutan, northwestern Yunnan and southeastern Xizang in China. In this study, the complete chloroplast genome of Pinus bhutanica was first assembled based on next-generation sequencing. The genome sequence was 116,919 bp in length with an overall GC content of 38.75%. A total of 106 functional genes were detected in the genome, including 72 protein-coding genes (PCGs), 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. The phylogenetic tree reconstructed by 12 chloroplast genomes revealed that P. bhutanica is most closely related to Pinus wangii in subsection Strobus of Pinus.

Complete chloroplast genome sequence of Pinus tabuliformis var. henryi (Mast.) C.T.Kuan 1983 (Pinaceae).

Project description:Pinus tabuliformis var. henryi (Mast.) C.T.Kuan 1983 is an endemic and rare subtropical pine, mainly distributed in central China. In this study, we sequenced the complete chloroplast (cp) genome of P. tabuliformis var. henryi and reported it for the first time. The cp genome was 119,634 base pairs (bp) in total length, including two inverted repeats (IRs, 495 bp), separated by a large single-copy region (LSC, 65,600 bp) and a small single-copy region (SSC, 53,044 bp). There are 114 different genes in the cp genome of P. tabuliformis var. henryi, including 74 protein-coding genes, 36 transfer RNA genes, and four ribosomal RNA genes. The overall GC content of the cp genome was 38.5%. Our phylogenetic analysis of P. tabuliformis var. henryi demonstrated that it was closely related to P. tabuliformis and could be used to identify and analyze its genetic diversity, which was expected to provide new data for taxonomic and phylogenetic studies of Pinus.

The complete chloroplast genome sequence of Abies chensiensis (Pinaceae: Abietoideae), an endangered species endemic to China.

Project description:Chloroplast (cp) genome sequences became a widely used tool for evolutionary and phylogenetic studies in plants. Abies chensiensis (Pinaceae: Abietoideae) is an endangered species endemic to China. To understand its evolutionary characteristics, the complete chloroplast genome of the A. chensiensis has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 121,784?bp in length and without a typical quadripartite structure due to the loss of IR region. The total GC content of whole genome sequence is 38.3%. The chloroplast genome encodes 109 genes, including 75 protein-coding genes, 30 transfer RNA genes and four ribosomal RNA genes. Among them, 35 genes involved in photosynthesis, while 58 genes involved in self-replication. The Maximum-Likelihood phylogenetic analysis showed a strong sister relationship with A. nephrolepis and A. koreana in Abietoideae. Our findings provide fundamental information for further evolutionary and phylogenetic researches of Abietoideae.
