Description

This IG 110813 Lens lamottei genome assembly (Lla.1ESP) was assembled using Oxford nanopore long reads (>5kb) at 42x coverage, resulting in 3695 contigs. The contiguity of the assembly was further validated and improved using HiC data and a genetic map (LR-74; IG 110810IG 110813IG 110813 x IG 110810 intraspecific RIL). The finished assembly is 3.238 Gb, 3.052 Gb of which are arranged in 7 pseudomolecules and 1517 unplaced contigs (94.2% anchored).

Analysis Method

Using the GenomeFocus workflow, long reads were assembled with smartdenovo and polished 3x with racon using short-read data. Due to the high degree of telomere tethering observed in Lens species, a genetic map (LR-74) was used to form the initial clusters for HiC data incorporation. ALLHiC is then used to order and orient contigs within each pseudomolecule cluster. Any corrections and a final manual check are made with Juicebox.
