High yield production of the antifungal proteins PeAfpA and PdAfpB by vacuole targeting in a TMV-based expression vector.

Summary: Fungi can cause terrible plant diseases that threaten our global food supply. Luckily, scientists have found special "antifungal proteins" in nature that can fight off these bad fungi. To make lots of these helpful proteins quickly, researchers used a clever trick: they turned a fast-growing tobacco plant into a tiny, living factory.

By adding special microscopic "shipping tags" to the proteins, they directed the plant cells to store them in a roomy compartment called the vacuole. This simple change boosted the amount of protein they could make by up to nine times! Best of all, these plant-made proteins work perfectly to protect crops, offering a safe, green way to keep our food safe from disease.
