Characterization of the complete chloroplast genome of Abies chensiensis (Pinaceae), an endemic to China.

ABSTRACT: Abies chensiensis, an endemic evergreen trees distributed in Qinling Mountains, is listed in China Species Red List as an endangered species. In this study, the complete chloroplast genome (cpDNA) sequence of Abies chensiensis was determined from Illumina pair-end sequencing data. The cpDNA is 121,329?bp in length, contains a large single copy region (LSC) of 72,843?bp and a small single copy region (SSC) of 46,126?bp, which were separated by a pair of inverted repeat (IR) regions of 1180?bp. The genome contains 120 genes, including 81 protein-coding genes, 4 ribosomal RNA genes, and 35 transfer RNA genes. The overall GC content of the whole genome is 38.3%, and the corresponding values of the LSC, SSC, and IR regions are 38.8, 37.1, and 37.5%, respectively. Phylogenetic analysis based on 20 chloroplast genomes indicates that A. chensiensis is closely related to A. sibirica.

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.

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.

Characterization of the complete chloroplast genome of Pinus wangii (Pinaceae), an endangered and endemic species in China.

Project description:The complete cp genome of Piuns wangii was 117,014 bp in size, containing a large single copy (LSC, 64,061 bp) region and a small single copy (SSC, 52,007 bp) region separated by two reduced inverted repeats (IRs, 473 bp). A total of 107 genes were predicted, including 73 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Most of the 51 simple sequence repeats (SSRs) were mononucleotides motifs of A/T types and were found to be located in non-coding regions. Phylogenetic analysis of Asian Pinus showed P. wangii clustered a strongly-supported clade with Pinus morrisonicola, Pinus sibirica, Pinus wallichiana, and Pinus pumila.

The complete chloroplast genome of Keteleeria davidiana var. calcarea (Pinaceae), an endangered species endemic to China.

Project description:Keteleeria davidiana var. calcarea is an endangered tree with considerable economic potential that used as timber wood for furniture and house construction. However, the natural population of K. davidiana var. calcarea is very fragmented, which is the cause for its low genetic diversity. In this study, we report the complete chloroplast genome of K. davidiana var. calcarea using Illumina sequencing. The chloroplast genome size is 117,670 bp in length, harboring a pair of very short inverted repeats (IRs) of 262 bp separated by a large single copy (LSC) sequence of 64,634 bp and a small single copy (SSC) sequence of 53,078 bp. The chloroplast genome K. davidiana var. calcarea contains 113 genes (74 protein genes, 35 tRNA genes, and 4 rRNA genes) and the overall GC content is 38.6%. The maximum likelihood phylogenetic analysis shows that K. davidiana var. calcarea is clustered with K. davidiana in genus Keteleeria. This complete chloroplast genome will help us to understand the evolution of K. davidiana var. calcarea and lays the foundations for future studies in this species conservation.
