Genetic evidence of mutator-induced deletions in the short arm of chromosome 9 of maize.
Evidence is presented that at least 12 of the Mu-induced yg2 mutants found in an extensive mutation analysis of this locus are the result of deletions in the region of the yg2 locus on the short arm of chromosome 9. Twelve of these putative deletions were characterized genetically, and in every instance, they were confirmed to be deletions involving chromosomal segments that include the yg2 and wd loci as well as additional portions of the short arm of chromosome 9.
