Introducing Genes from other Organisms to Improve Efficiency Besides using just genes from the plant itself, scientists have been able to introduce other genes from other organisms into the plant cells, one of the first being (Fructose-1, 6-Sedoheptulose-1, 7-biphosphate). The (Fructose-1, 6-Sedoheptulose-1, 7-biphosphate) gene comes from cyanobacteria and was introduced to a transgenic tobacco plant. Once again, through the use of overexpression, the tobacco plant showed an increased photosynthetic rate and increased product yield. Being introduced into the plant’s chloroplast, the mutant gene had a much higher yield than the wild type gene. The mutant gene tobacco plant had increases in dry weight, photosynthetic rate, and Rubisco efficiency. Isopentenyl transferase is another gene that has been introduced to tobacco plants to determine its effects. The Isopentenyl transferase gene comes from the tumour inducing plasmid of Agrobacterium tumefaciens. The interesting thing about this gene is how the gene doesn’t need to be overexpressed to have an effect on the plant. Just by expressing this gene in the tobacco plant there is an increase in the plant’s yield, photosynthetic rate, and studies have also shown that it delays the process of biological aging within the leaves.

Results These experiments have shown multiple advantages to genetically engineering plants to improve their efficiency. The following table shows the “Photosynthesis rate and internal CO2 concentration…
