Rust is caused by fungi that have reddish spores that emerge from the leaves of infected plants. Therefore, the best preventive strategy for addressing the cellular basis of rust would be to treat the plant to eliminate the fungi that causes the rust. This can be achieved through the use of fungicides or other methods of biological control. Treating the soil or making the plant resistant to the enzymes that cause rust would not be effective in this case, as the underlying cause of rust is the presence of fungi on the plant. Eliminating the fruiting bodies that are recognized as rust would also not be effective, as the rust-colored mushrooms are not the direct cause of the problem.
