Abstract
A plasmid comprising a phosphoenolpyruvate carboxylase gene and promoter isolated from maize. The phosphoenolpyruvate carboxylase gene encodes a phosphoenolpyruvate carboxylase isozyme involved in C.sub.4 photosynthesis and which is not expressed in seeds.
Claims6
A plasmid comprising a phosphoenolpyruvate carboxylase gene isolated from maize and contained in DEI PEP 10.
A plasmid comprising a promoter from a phosphoenolpyruvate carboxylase gene isolated from maize and contained in DEI PEP 10.
An isolated DNA fragment comprising promoter of a phosphoenolpyruvate carboxylase gene isolated from maize and contained in DEI PEP 10.
A chimeric gene comprising a promoter derived from a phosphoenolpyruvate carboxylase gene isolated from maize and contained in DEI PEP 10 ligated to a heterologous structural gene.
A process for transforming plant cells which comprises contacting plant cells with a vector containing a nucleic acid material for introduction to the plant cell during transformation and recovering transformed plant cells, the improvement which comprises using a vector comprising a phosphoenolpyruvate carboxylase gene isolated from maize and contained in DEI PEP 10.
