Identification of a gene deletion in a region associated with the dar-1 phenotype. Analysis of progeny of a mapping cross between the dar-1 mutant and ecotype A20 revealed linkage of the dar-1 lesion to a 6 Mb region between nucleotide positions 22 and 28 Mb on chromosome 2 (in red). A deletion of between 8 and 17 kb was identified in dar-1 near nucleotide position 23.1 Mb which included a single gene, MtrunA17_Chr2g0304631
