What Does PGIP Stand For?

PGIP stands for Polygalacturonase Inhibiting Protein

Polygalacturonase Inhibiting Protein (PGIP) is a plant-derived protein that plays a critical role in plant defense mechanisms. It functions primarily by inhibiting the activity of polygalacturonases, enzymes produced by pathogens that degrade pectin in plant cell walls. By limiting the activity of these enzymes, PGIP helps to strengthen the plant's structural integrity and enhance its resistance to fungal and bacterial attacks. This protein is significant for understanding plant-pathogen interactions and developing disease-resistant crop varieties.
