CHROMOSOMAL LOCATION BY USE OF TRISOMICS AND NEW ALLELES OF AN ENDOPEPTIDASE IN ZEA MAYS

[摘要] An association was found earlier between the Ep1 gene locus coding for an endopeptidase and the endosperm color gene Y1 on chromosome 6 of Zea mays . By employing primary trisomics we have unequivocally placed the Ep1 gene on chromosome 6, closely linked to the Y1 locus. Additionally we describe new alleles at the Ep1 locus, and present evidence for the existence of a second endopeptidase system in maize.
