Abstract: The invention relates to the DNA and protein encoded by the GA4 locus. This protein is believed to be a member of the family of enzymes involved in the biosynthesis of the gibberellin family (GA) of plant growth hormones which promote various growth and developmental processes in higher plants, such as seed germination, stem elongation, flowering and fruiting. More specifically, the protein encoded by the GA4 locus is an hydroxylase. The invention also relates to vectors containing the DNA and the expression of the protein encoded by the DNA of the invention in a host cell. Additional aspects of the invention are drawn to host cells transformed with the DNA or antisense sequence of the invention, the use of such host cells for the maintenance, or expression or inhibition of expression of the DNA of the invention and to transgenic plants containing DNA of the invention. Finally, the invention also relates to the use of the protein encoded by the GA4 locus to alter aspects of plant growth.
