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.
