This genome browser provides access to data generated as part of the Chiplett and Compositae Genome Projects. The genetic map used to build the chromosomal-like sequences was based on segregation data from duplicate hybridizations of 213 RILs derived from L. sativa cv Salinas x L. serriola UC96US23 to a custom Affymetrix Genechip (Lettuce Genetic Map). The map contains 4755 genetics bins representing 1350 markers sorted in nine chromosomal linkage groups. Gaps between sequences are represented by "Ns" scaled to genetic distances (cM) between genetic bins (conversion factor 1.7Mb per cM). The orders of sequences that cosegregate in the same genetic bins are aribtrary.

This genome browser provides access to the genomic scaffolds generated in the Beijing Genome Institute (BGI). It contains 21513 scaffolds that are 1Kb and bigger.

GBrowse v2.1

This version display pseudo-genomic chromosomes based on genetic positions associated to the genomic scaffolds. The genetic positions were calculated based on the markers that map to each of the scaffolds and the pseudo chromosomes were build scalling the distance between scaffolds to a artifial repetitive sequence "NANCNGNT" (793000 bases per cM) to differentiate for the runs of N's generated from the scaffolding.

From the ~14000 markers present in the ultra-dense lettuce genetic map we were able to uniquely map ~11000 into 3093 scaffolds, these scaffolds are the base for the pseudo chromosomes and contains 1.5Gb of sequence.

This version contain the same tracks has the GBrowse v2, it corresponds to a subset of the scaffolds.
