- What Can Be Done to Protect Genetic Diversity?
The ability for different species to mate, also known as hybridization, has allowed for the vast diversity of wild plant types we see in the environment today. However, this process is not restricted to wild plants and can occur between any type of plant, including wild crops and GMOs, if they are reproductively compatible. When GM plants are in cl...
In addition to crossbreeding, GMOs can also affect genetic diversity through uncontrolled growth of a genetically engineered population. If advantageous genes are introduced into GMOs, it may allow them to become more fit than their wild relatives. This situation would be detrimental because the GMOs would grow faster and reproduce more often, allo...
Although there is little evidence that GMOs have impacted genetic diversity in today’s environment, scientists and ecologists are very aware of the potential influence that GMOs have on biodiversity. Therefore, researchers are investigating how to better prevent crossbreeding and spreading of GMOs, similar to the physical and biological containment...
Jul 11, 2019 · In Uganda, field trials are being conducted with potato expressing a stack of immune receptors providing protection against potato late blight disease, as well as bananas that are resistant to bacterial wilt (Fig. 2 a; L. Tripathy et al., 2014; Ghislain et al., 2019).
Oct 20, 2022 · Late blight, caused by Phytophthora infestans, is the most devastating disease in potato production. Here, we show full late blight resistance in a location with a genetically diverse pathogen population with the use of GM potato stacked with three resistance (R) genes over three seasons.
