Annotation of Siberian Larch (Larix sibirica Ledeb.) Nuclear Genome-One of the Most Cold-Resistant Tree Species in the Only Deciduous GENUS in Pinaceae.

ABSTRACT: The recent release of the nuclear, chloroplast and mitochondrial genome assemblies of Siberian larch (Larix sibirica Ledeb.), one of the most cold-resistant tree species in the only deciduous genus of Pinaceae, with seasonal senescence and a rot-resistant valuable timber widely used in construction, greatly contributed to the development of genomic resources for the larch genus. Here, we present an extensive repeatome analysis and the first annotation of the draft nuclear Siberian larch genome assembly. About 66% of the larch genome consists of highly repetitive elements (REs), with the likely wave of retrotransposons insertions into the larch genome estimated to occur 4-5 MYA. In total, 39,370 gene models were predicted, with 87% of them having homology to the Arabidopsis-an
