A DISEASE RESISTANCE GENE FROM MAIZE AND ITS USE FOR DISEASE RESISTANCE, AS A SELECTABLE MARKER AND AS A GENE IDENTIFICATION PROBE

摘要

The HM1 gene in maize confers race-specific resistance to the pathogen, Cochliobolus carbonum. We have used transposon mutagenesis to tag, clone, and characterize several HM1 alleles. The gene can be used as a selectable marker in conjunction with the toxin produced by C. carbonum.
