Аннотация: The genetic differentiation of Siberian larch (Larix sibirica Ledeb.) populations along the latitudinal gradient of climatic conditions was studied using high-throughput double digest restriction-site associated DNA sequencing (ddRADseq) data. We studied correlation of five main climatic variables with variation of 47.929 single nuПоказать полностьюcleotide polymorphisms (SNPs). In total, 125 trees were genotyped and studied: 61 trees in four populations along the western geographic transect and 64 trees in four populations along the eastern geographic transect. Twenty-one SNPs with signatures of selection were identified, including nine outlier SNPs whose variation cannot be explained by selectively neutral processes, and 12 SNPs whose variation correlated with the environmental factors. Seven SNPs are located in the introns of mitochondrial genes NAD1, NAD2 and ribosomal protein gene L2, three are located relatively close to the mitochondrial genes encoding NAD2 and ribosomal proteins S7 and S11, one is located at a distance from the nuclear gene encoding a protein homologous to the microtubule-associated futsch-like protein of Arabidopsis thaliana, two in the tentative protein genes of unknown nature and three in contigs containing no genes, and for which no homologous sequences were found in the NCBI GenBank.
