Description
This CDC Greenstar Lens culinaris genome assembly (Lcu.1GRN) was assembled using highly accurate long read sequencing, or HiFi reads (37x coverage) and the assembler LRA, resulting in 1635 contigs. Scaffolding of the contigs was done using Irys optical mapping data and these were aligned to the CDC Redberry 2.0 assembly and ordered relative to that reference. Further validation was done using genetic maps with CDC Greenstar as one of the parents. The finished assembly is 3.839 Gb, 3.799 Gb of which are arranged in 7 pseudomolecules.

Analysis Method

37x coverage of HiFi reads >10kb in length were assembled using the default parameters of LRA. Irys optical mapping data was used to further scaffold the 1635 contigs. These scaffolds were aligned to the CDC Redberry 2.0 assembly and ordered relative to that reference. This pseudomolecule assembly was checked against genetic maps with CDC Greenstar as one of the parents, as confirmation for scaffold ordering.
