The purpose of the proposed research is to investigate two                 gibberellin biosynthesis mutants of Pisum sativum.  The le and na               mutant alleles block the biosynthesis of gibberellins, each at a                specific site in the gibberellin pathway.  It is proposed to                    quantify gibberellin levels in constituent organs of the isogenic               lines througout development, using capillary gas chromatography-                mass spectrometry.  By monitoring gibberellin levels it will be                 possible to determine the tissue-specificity and ontogenetic                    specificity of these genes.                                                         The significance of this research is the potential to                       determine how the levels of the endogenous gibberellin A1, which                is active in regulating internode extension, causes a dwarf pea                 phenotype.  The findings generated by this work will lay the                    foundation for more molecular studies in the future and they may                lead to the discovery of commercially useful peas, i.e., dwarf                  pea with normal pod size.
