Whole-genome resequencing of BC1 populations from Arabidopsis (Col x Ler) x Col crosses (wild type, HEI10oe, zyp1, and zyp1 HEI10oe). Whole-genome resequencing of BC1 populations from Arabidopsis (Col x Ler) x Col crosses (wild type, HEI10oe, zyp1, and zyp1 HEI10oe)

This experiment aims at analyzing crossover distribution in male and female meiosis, in the Arabidopsis HEI10oe, zyp1, and zyp1 HEI10oe compared to wild type. Plants double heterozygous of zyp1-1+/- HEI10oe (Col) were crossed with zyp1-6+/- mutant plants (Ler) to generate zyp1-1/zyp1-6 HEI10oe heterozygous, HEI10oe heterozygous, zyp1-1/zyp1-6 and wild type in Col/Ler hybrid background, and then crossed as male or as female with wild-type Col. Backcross populations were grown in the greenhouse (16 h day/8 h night) for 3 weeks and 4 days in the dark, 100-150mg leave samples from plants from the 8 obtained BC1 populations were used for DNA purification and library preparation for Illumina sequencing (HiSeq 3000 2x150 bp), performed by the Max Planck-Genome-centre Cologne, Germany (https://mpgc.mpipz.mpg.de/home/).
