  • Plant genes affecting gibberellic acid biosynthesis
    Patent number: 5612191
    Abstract: Genes controlling gibberellic biosynthesis are used in genetic engineering to alter plant development. Alterations in the nature or quantity of products of the genes affects plant development. A family of genes in monocots encodes a cyclase involved in the early steps of gibberellic acid (GA) biosynthesis. A member of the family, the gene An1, is identified in maize and cloned and the function of the gene is characterized. Using recombinant genetic technology, GA levels are manipulated. Changes in GA levels alter monocot plant phenotypes, for example, height and fertility.

  • Disease resistance gene from maize and its use for disease resistance as a selectable marker and as a gene identification probe
    Patent number: 5589611
    Abstract: 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.
