This research analyzes gibberellin (GA) biosynthesis in relation                to shoot growth in maize.  The approach combines the disciplines                of chemistry (organic synthesis), biochemistry (radiolabelled                   feeds and enzymology) and genetics (molecular and physiological).               The specific goals of this research are to use GA mutants (and                  normals):  (1) to analyze gene expression in callus tissue                      cultures;  (2) to identify maize GA conjugates and analyze                      conjugation in seedlings;  (3) to correlate levels of GA1 with                  the short and intermediate alleles of d1 mutant seedlings;  (4)                 to locate the steps in the GA biosynthetic pathway blocked by the               d2, d3 and an1 mutants;  (5) to analyze the biosynthetic origin                 of GA3 in maize shoots from feeding studies with labelled GA4,                  GA7 and 2,3-dehydro-GA9;  (6) to study the properties of normal                 and mutant hydroxylase, the enzyme controlling the step GA20 to                 GA1;  (7) to continue preliminary studies on cloning the dwarfing               genes; and  (8) to continue classical genetic studies with                      mutants of maize concerned with GA metabolism.                                                                                                                  GAs are plant hormones that regulate many plant responses                       including shoot elongation.  In maize, plants lacking endogenous                GA1 possess a dwarf habit of growth.  Five dwarf mutants (GA                    mutants) are used to unravel details of the GA biosynthetic                     pathway, and to define the role of specific GAs in the control of               GA dependent shoot elongation.
