Аннотация: 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 thedata of the whole genome sequencing of three Siberian larch trees from different regions - theUrals, 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 ofthe 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 122,561bp, which is similar to 122,474bp in the closely related European larch (Larix decidua Mill.). As a result of annotation and comparison of the data with theexisting data available only for three larch species - L. decidua, L. potaninii var. chinensis (complete genome 122,492bp), and L. occidentalis (partial genome of 119,680bp), 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.

Аннотация: Лиственница сибирская Larix sibirica Ledeb. является одной из преобладающих бореальных пород в Евразии и имеет высокую экономическую и экологическую ценность. Однако, несмотря на это, разработка и использование микросателлитных маркеров для ее исследования остаются недостаточными. Микросателлитные маркеры уже долгое время являются признанным инструментом для оценки популяционной изменчивости и структуры видов. В настоящей работе был проведен поиск простых три-, тетра-, пента- и гексануклеотидных тандемных повторов в геномной референсной de novo сборке лиственницы сибирской, локусы которой легко генотипируются даже путем простого гель-электрофореза. Всего было найдено более тысячи предположительных микросателлитных локусов. На основе этих данных были разработаны и проверены 60 пар олигонуклеотидных ПЦР праймеров. По итогам тестирования праймеров на образцах ДНК из трех видов лиственницы (L. sibirica Ledeb., L. gmelinii (Rupr.) Rupr. и L. cajanderi Mayr.) были отобраны 14 наиболее перспективных полиморфных локусов, которые могут успешно применяться для изучения и идентификации не только лиственницы сибирской, но также лиственниц Гмелина и Каяндера.
Siberian larch Larix sibirica Ledeb. is one of the major boreal tree species in Eurasia and has a considerable economic and ecological value. Despite that importance, the development and use of microsatellite markers in this species remain limited. Microsatellite markers are considered to be a valuable tool for estimation of population diversity and structure. Availability of draft reference assembly of the Siberian larch genome allowed us to identify 1015 microsatellite loci or simple sequence repeats (SSRs) with tri-, tetra-, penta- and hexa-nucleotide motifs. For 60 of them PCR primers were designed and tested for amplification in L. sibirica and for their cross-genus transferability to L. gmelinii (Rupr.) Rupr. and L. cajanderi Mayr. Here we present a set of 14 reliable and polymorphic nuclear SSR markers that can be used for further population genetic studies, breeding programs and timber origin identification.
