Arabidopsis Bay X Sha Genotypes Database

    Summary:

The Bay-0 x Shahdara genetic reference population consists of 420 recombinant inbred lines (RIL). This set was created by Olivier Loudet and Sylvain Chaillou between 1997 and 2000 at the INRA in Versailles, France. This plant has a genome consisting of five chromsomes and a total of 125 megabases of DNA, equivalent in length to a single human chromosome. However, the genome is nonetheless rich and contains approximately 26,000 genes. Full sequence data are available for this species. (The Col-0 accession was sequenced.)

The 420 RILs were derived from a cross between Bay-0 (accession N954) and Shahdara (accession N929); two accessions obtained from the NASC European Arabidopsis Stock Centre. Bay-0 and Shahdara were chosen because of their well characterized genetic, geographical, and ecological differences. Lines were propagated by single seed descent through the sixth generation (F6) without selection. One plant per line was then used for genotyping (420 RILs x 38 markers) and selfed to obtain F7 seeds. F8 seed stock generated by bulk multiplication of F7 plants are available for analysis for 411 of these RILs. Data sets in WebQTL include up to 415 BXS accessions and the two parental stock.

    About the genotypes used in these studies:

This Bay x Sha Arabidopsis genotype data set is described in Loudet and colleagues (2002). This marker data set consists of 38 markers for 420 strains. It is used to map QTLs for phenotypes listed in the BayxSha Published Phenotypes data set.
