Generation of Da(1)-12×Ei-2 Recombinant Inbred Lines

This recombinant inbred population was produced by the Kroymann group by crossing the ecotypes Da (1)-12 and Ei -2. Da(1)-12 (accession no. N917) and Ei-2 (N1124) accessions were obtained from the Arabidopsis stock center (Nottingham, U.K.). Except for the initial cross between both accessions, all following generations were propagated by selfing. 215 F2 plants were randomly selected from the progeny of a single heterozygous F1 plant. For every advanced generation, 4–8 seeds per line were planted, and a single plant was randomly chosen from each line for seed production. Finally, seeds from a single F8 plant per line were bulk-collected resulting in a final set of 202 Da(1)-12×Ei-2 RILs.

Genotyping and genetic map

Molecular markers were obtained from publicly available sources, or were generated from microsatellite loci identified in the Col-0 genome sequence. More than 150 potential markers were tested for polymorphism between parental lines, using DNA from Da(1)-12, Ei-2, and a 1:1 mixture of DNAs from both lines. 84 PCR products were found suitable for genotyping, and allowed to distinguish between Da(1)-12 and Ei-2 genotypes, and between homozygous and heterozygous loci. Genotyping was carried out with DNA extracted from individual F9 progeny. Genotype data for the Da(1)-12×Ei-2 RILs is available in the publication below.
