2. From animals to plants: Yes, while perhaps not as common as plant-to-plant or microorganism-to-plant transfers for agricultural purposes, it is technically possible to transfer genes from animals to plants using genetic engineering techniques. This has been explored in research for various purposes.
3. From microorganisms to higher organisms: Yes, this is a very common application. For instance, transferring genes from bacteria (like the Bt gene) to plants for pest resistance (e.g., Bt cotton), or inserting genes from humans into bacteria or yeast for the production of therapeutic proteins like insulin.
