Abstract excerpt
We present the first reference genome of the highly heterozygous autotetraploid Allium porrum (leek). Combining long-read sequencing with single-nucleotide polymorphism (SNP)-array screening of two experimental F1 populations, we generated a genetic map with 11,429 SNP markers across eight linkage groups and a chromosome-scale assembly of A. porrum (leek) totaling 15.2 Gbp in size. The high quality of the...
