The rpoa gene of agrobacterium tumefaciens

摘要

Nucleic acid constructs for expressing a heterologous gene which contain a nucleic acid sequence encoding at least a portion of the alpha -subunit of an RNA polymerase obtained from the same genus as the heterologous gene and methods of using these constructs to express heterologous genes are provided. Also provided is a nucleic acid molecule encoding the alpha -subunit of an Agrobacterium RNA polymerase.
