"GENETICALLY ENGINEERED PLANT, PLANT PRODUCTION PROCESS, MUTANT VITREOSCILLA HEMOGLOBIN PROTEIN, POLYNUCLEOTIDE, HOST CELL, AND PROCESSES TO GENERATE A DETERMINING DETERMINATION OF DETERMINING DETERMINATION. The present invention relates to the genetic engineering of plants for improved oxygen assimilation and utilization. More specifically, this invention relates to the production of transgenic plants engineered to express globin proteins such as, for example, hemoglobin, myoglobin and hemoproteins. The engineered plants of the invention achieve faster germination, are of faster growing or maturing cultures, produce higher crop yields, and / or contain higher levels of desired plant metabolites, particularly alkaloids. The invention also relates to mutant Vitreoscilla hemoglobin proteins, polynucleotides encoding them, and host cells containing such polynucleotides. |
