Background: The 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).
Results: We used data of the whole genome sequencing of three Siberian larch trees from different regions - 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 in 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 SciRoKo 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 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.
Conclusions: The 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.I

Eight Clusters, Synchrony of Evolution and Unique Symmetry \\in Chloroplast Genomes: The Offering from Triplets
Садовский, Михаил Георгиевич; Сенашова, Мария Юрьевна; Путинцева, Юлия Андреевна (2018-07)We studied the features and characters of various chloroplast genomes that could be retrieved solely from the analysis of triplet composition. To do that, two types of triplet dictionaries were developed: the former lists ... -
Chloroplast Genomes Exhibit Eight-Cluster Structuredness and Mirror Symmetry
Садовский, Михаил Георгиевич; Сенашова, Мария Юрьевна; Малышев, Андрей Валерьевич (2018-04)Chloroplast genomes have eight-cluster structuredness, in triplet frequency space. Small fragments of a genome converted into a triplet frequency dictionaries are the elements to be clustered. Typical structure consists ... -
