When genes are transplanted into poplar trees, the result is transgenic trees that grow more quickly and absorb more CO2 than conventional poplars do.
Slowing global climate change by reducing the amount of carbon dioxide in the atmosphere is one technique for doing so. Planting trees is one of the most fundamental ways that may be employed to achieve this goal. Because green plants collect carbon dioxide from the atmosphere and use it to make food through the process of photosynthesis, they are considered carbon sinks. As a result of the body's growth, a considerable proportion of carbon absorbed from the environment is not released back into the atmosphere as rapidly as it would otherwise be.
Variables such as temperature, humidity, and soil type all affect plants' ability to absorb carbon from the environment. The rate at which photosynthesis occurs is undoubtedly one of the most important of these factors. A technique for creating phosphoglycolate, which is a detrimental byproduct of photosynthesis, may be found in almost all plants. The upshot is that some of the energy that could have been used to develop is instead diverted to the process of rendering the hazardous waste harmless.
Researchers at the biotech company Living Carbon employed gene transfer to increase the efficiency of photosynthetic processes. During the research, genes from squash and green algae were transplanted into poplar trees. The specifics of the studies are outlined in the published overview on bioRxiv. Photosynthetic efficiency is improved by the introduction of new genes that convert the toxic phosphoglycolate generated into sugars that may be used to fuel plant development.
Internally, the researchers grew transgenic and non-transgenic poplars alongside one another for four months. In the study, the researchers discovered that transgenic poplars grew 1.5 times faster and gained 53 percent more mass than ordinary poplars.
Trees in the open air may require more water and fertilizer to develop at the same rate as those in a laboratory, according to the findings, which were restricted to a laboratory environment only. In addition, it is asserted that when trees are prevented from obtaining sunlight by other trees, their growth may be hampered.
