The complete chloroplast genome sequence of Tamarix arceuthoides Bunge and Tamarix ramosissima Ledeb. (Tamaricaceae).

ABSTRACT: Tamarix L. is of great ecological and economic significance in arid desert ecosystems. This study reports the complete chloroplast (cp) genomic sequences of T. arceuthoides Bunge and T. ramosissima Ledeb., which are currently unknown, by high-throughput sequencing. The cp genomes of T. arceuthoides 1852 and T. ramosissima 1829 were 156,198 and 156,172 bp in length, respectively, and contained a small single-copy region (SSC: 18,247 bp), a large single-copy region (LSC: 84,795 and 84,890 bp, respectively), and a pair of inverted repeat regions (IRs: 26,565 and 26,470 bp, respectively). The two cp genomes possessed 123 genes arranged in the same order, including 79 protein-coding, 36 tRNA, and eight rRNA genes. Of these, 11 protein-coding genes and seven tRNA genes contained at least one intron. The present study found that Tamarix and Myricaria are sister groups with the closest genetic relationship. The obtained knowledge could provide useful information for future phylogenetic, taxonomic, and evolutionary studies on Tamaricaceae.

Project description:BackgroundThe main objectives of this study were sequencing, assembling, and annotation of chloroplast genome of one of the main Siberian boreal forest tree conifer species Siberian larch (Larix sibirica Ledeb.) and detection of polymorphic genetic markers - microsatellite loci or simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs).ResultsWe used the data of the whole genome sequencing of three Siberian larch trees from different regions - the Urals, Krasnoyarsk, and Khakassia, respectively. Sequence reads were obtained using the Illumina HiSeq2000 in the Laboratory of Forest Genomics at the Genome Research and Education Center of the Siberian Federal University. The assembling was done using the Bowtie2 mapping program and the SPAdes genomic assembler. The genome annotation was performed using the RAST service. We used the GMATo program for the SSRs search, and the Bowtie2 and UGENE programs for the SNPs detection. Length of the assembled chloroplast genome was 122,561 bp, which is similar to 122,474 bp in the closely related European larch (Larix decidua Mill.). As a result of annotation and comparison of the data with the existing data available only for three larch species - L. decidua, L. potaninii var. chinensis (complete genome 122,492 bp), and L. occidentalis (partial genome of 119,680 bp), we identified 110 genes, 34 of which represented tRNA, 4 rRNA, and 72 protein-coding genes. In total, 13 SNPs were detected; two of them were in the tRNA-Arg and Cell division protein FtsH genes, respectively. In addition, 23 SSR loci were identified.ConclusionsThe complete chloroplast genome sequence was obtained for Siberian larch for the first time. The reference complete chloroplast genomes, such as one described here, would greatly help in the chloroplast resequencing and search for additional genetic markers using population samples. The results of this research will be useful for further phylogenetic and gene flow studies in conifers.
