The first bioluminescence in plants was achieved by genetically modifying tobacco plants. This was accomplished by using luciferase from a species of fireflies known as Photinus pyralis. The protein was expressed with the cauliflower mosaic virus promoter and luciferin was added to the genetically modified plants by watering them with it. This produced light emission when the plants were placed on a photographic film. Although this was successful, the light could only be produced when the substrate luciferin was added to the plants. The gene sequence for luciferase has already been identified, however the sequence for the production of luciferin is still not known. This can change due to the fact that DNA sequencing is faster and cheaper now, but until then the addition of the substrate luciferin is required for the plants to glow.
The oxidation of luciferin by luciferase produces oxyluciferin which cannot be used to produce light anymore. It is a competitive inhibitor for the production of luminescence since it can block the active site on the enzyme luciferase. However, researchers identified an enzyme that has the ability to recycle this used up luciferin substrate. The enzyme is called luciferin regenerating enzyme or LRE and it can recover D-luciferin with the help of D-cysteine. The LRE can remove the oxyluciferin with the addition of D-cysteine providing a step towards prolonging the light output from the organism.
Bacterial luminescence is also another possible way for plants being able to produce light. Some of the known bacteria that are luminescent are found in the genera Aliivibrio, Photobacterium, Alteromonas, and Photorhabdus. The light emission system present in the bacteria is encoded by the gene known as lux o...

... luminous flux. A genetically engineered plant that produces light must have a minimum output of 1000 lumens in order to be comparable with conventional lighting. Fast growing trees have a photosynthetic efficiency, which is the fraction of light energy that can be converted to chemical energy, of about 2% of the total solar energy. This means about 28 W/m2 can be absorbed and stored within the plants. If a tree absorbs this amount of energy during midday, it would only have about half the energy by night time. The tree could be genetically modified in order to only output the light when it is dark which would allow for a greater output. This can be made possible by diverting a portion of the available surplus of energy in the tree to the production of light. The procedure to be able to achieve this may be challenging but it can be made possible with more research.

Tobacco Production Of The Tobacco Plant Nicotiana Tabacum Essay

- Nicotine is the substance found in the tobacco plant Nicotiana tabacum, that is often administered through the smoking of cigarettes, pipes, and cigars or via smokeless tobacco such as chew or snuff. All of these products introduce the addictive substance nicotine, (C10H14N2), into the body. Smoking has been largely popular throughout the United States since the colonization of the country. In fact tobacco production was largely responsible for the United States’ upbringing and rise to success as it generated a large profit and provided a popular substance to many....   [tags: Tobacco, Nicotine, Cigarette, Tobacco smoking]

Tobacco: The Original Addictive Substance Essays

- The tobacco of the south has shaped the United States in history and today. The tobacco plant was discovered by Christopher Columbus, and he then brought it back to England when he returned from his voyage. England began to be addicted to tobacco. Its residents spent more than 200,000 euros on the crop a year in the 1600’s (“History 1492-1762”). Since the discovery of the tobacco plant, it has been well sought after and a large cash crop. Big tobacco companies attempt to hide the real effects of smoking their products, and aim their campaigns toward teenagers....   [tags: drugs, tobacco]

Slavery And Tobacco Production On The Land Essay

- The late 1700’s and early 1800’s were a very pressing time in history regarding slavery and tobacco production. There were numerous altering opinions on these topics, and some were voiced better than others. The people that were more concerned with these issues wrote articles about them. The first article was written in 1775 when a traveller wrote about the effects tobacco production on the land in Virginia and Maryland. About twelve years after that, Thomas Jefferson wrote his article on his thoughts of slavery and how he believed that blacks were naturally inferior to whites....   [tags: Black people, Slavery in the United States]

Genetic Modification Using the CRISPR-Cas9 Method in Crop Plants Essay

- Before targeedt genome engineering emerged there was classical plant breeding and transgenic methods to modify crop plants, and ensure sustainable production. Researchers today have utilized methods like zinc finger nucleases (ZNF) and TAL effector nucleases (TALENs) to create these improved crop plants. Recently, a new method has caught the eye of many researchers; a method that simplifies the process and saves labor: CRISPR-Cas9 system. This method of genome engineering is particularly interesting not only for researchers but also for millions of Americans....   [tags: CRISPR-Cas9, genome engineering, plants]
