Tobacco Nia2 cDNA functionally complements a Hansenula polymorpha yeast mutant lacking nitrate reductase. A new expression system for the study of plant proteins involved in nitrate assimilation.

Abstract excerpt

An integrative expression vector based on promoter and terminator transcriptional sequences from the Hansenula polymorpha nitrate reductase gene (YNR1) has been developed to express nitrate assimilation plant genes in the nitrate assimilatory yeast H. polymorpha. Using this vector a plant nitrate reductase cDNA (tobacco Nia2) was expressed for the first time in a nitrate assimilatory yeast. The heterologous...
