Natural and artificial selection
This is the visible part of the project, which could lead to a breakthrough in soil decontamination. The project is called Improving Bioremediation of Polluted Soils Through Environmental Genomics and it requires time-consuming sampling and fieldwork as well as DNA sequencing of the species in question. The project involves 16 researchers from the University of Montreal and McGill University, many of which are affiliated with the IRBV. The team also includes four researchers, lawyers and political scientists, specializing in the ethical, environmental, economic, legal and social aspects of genomics.
The principle is based on a well-known process in the sector called phytoremediation that consists in using plant matter for decontamination. "However, in contaminated soils, it isn't the plant doing most of the work," says Lang. "It's the microorganisms i.e. the mushrooms and bacteria accompanying the root. There are thousands of species of microorganisms and our job is to find the best plant-mushroom-bacteria combinations."
Botanist Michel Labrecque is overseeing the plant portion of the project. The willow seems to be one of the leading species at this point given its rapid growth and premature foliation. In addition, its stem grows even stronger once it has been cut. Therefore, there is no need to plant new trees every year. However, the best willow species still needs to be determined.
One of the best in the country
By investing 7.6 million dollars over three years, Genome Canada, Genome Quebec and other partners are expecting concrete results in the soil decontamination market, which is estimated at 30 billion dollars in Canada alone. "The fact t
