Identifying crossover locations in Arabidopsis thaliana asy1/+ Col × Ler F2 populations using genotyping-by-sequencing

Genomic DNA from 191 asy1/+ Col x Ler F2 individuals was extracted using CTAB and used to generate sequencing libraries as described (Lawrence et al, 2019 Current Biology). Sequencing data was analysed to identify crossovers using the TIGER pipeline as previously described (Rowan et al, 2015 G3 (Bethesda); Yelina et al, 2015 Genes & Dev; Lawrence et al, 2019 Current Biology).
