around the leaf tissue, and volotile organic compounds diffuse into the
cell cytoplasm; there, it's just converted by a cytochrome or other
enzyme into something the cell can use, or is just detoxified and dumped.
I would also bet that this is a system that is present in most plants but works better at filtering pollutants in some plants than others, and that involves dozens of genes. Just figuring out which genes, and what would be a minimal set to be moved into other plants, may be a multi-year project.
Not something I would want to work on without doing a very thorough search of the literature first...
