Chromium toxicity to plant seeds and mechanism of action
Mining of chromium and its use in industrial activities can impact the environment as may happen in Northern Ontario were large chromium deposits were discovered. This project aimed at determining impacts of chromium exposure on native plants, including species from the Nibinamik Indigenous Peoples region in the Ring of Fire. Seed germination assays and a germinable seed study from soil seedbanks (using soil samples collected from the Ring of Fire) were conducted. Mutants of the model species Arabidopsis thaliana with known seed coat components (different levels of suberin, lignine and mucilage) are being tested to determine the mechanism of chromium toxicity.
