Canadian scientists have developed a quick method for detecting the DNA of plant pests
Scientists at the University of British Columbia (Canada) have developed a new rapid DNA detection method that identifies pests and pathogens in less than 2:00, without the use of complex processes or chemicals, writes Phys.org.
According to the researchers, this method will significantly save time for photo monitoring, as well as not wait for laboratory results that will confirm or deny the involvement of pathogens in the damage.
Relevant research is focused on using genomics to develop better methods for identifying and monitoring invasive pests and pathogens that threaten plants. For nearly 25 years, scientists have been looking for a quick, accurate, and inexpensive DNA test that can be performed anywhere, regardless of distance from each other.
The essence of the method proposed by the scientist is that small fragments, such as leaves or stems, are lowered into a tube and placed in a small battery-powered device. The device checks if these DNA fragments match the genomic material of the target species and generates a signal that can be visualized on a connected smartphone.
For research, you can also use the fragments of identified pests.
“With this system, we can determine with almost 100% accuracy whether this is a coincidence or not, if we are looking at a threatening invasive species or one that is benign. We can analyze up to nine samples from the same species or different species at the same time. The device is lightweight, less than one and a half kilograms, so you can take it with you over long distances”, – said Richard Hamelin, one of the authors of the development.
