Abstract

Sucrose phosphate synthase (SPS), a process for its preparation, its DNA, and utilization of DNA encoding SPS to modify the expression of SPS in the plant cells are provided. Methods and compositions for producing SPS protein and DNA encoding SPS from a number of sources are provided. Also provided are transgenes comprising DNA encoding SPS and methods for the production of transgenic plant cells and plants which have extra SPS activity, and thus an increased capacity to synthesize sucrose. Transgenic plant cells and plants with the additional SPS activity exhibit altered carbon partitioning, growth and development, and yield under a variety of conditions.
