摘要

Plants lack the system of circulating antibodies, thus defense mechanism in plants depends on the capability of recognition and interaction with the invading pathogenic microorganisms and neutralising their effect via specific interactions. The first barrier of defense in plants is the cell wall made up of pectin consisting of homogalacturonan, rhamnogalacturonan I and rhamnogalacturonan II. The major component of pectin is homogalacturonan. Pathogenic fungi secrete polygalacturonase (PG) to degrade the homopolygalacturonan of cell wall. Thus plants have pathogenesis-related protein in the cell wall to neutralise the effect of PG known as polygalacturonase inhibiting protein (PGIP). The interaction between PGIP and PG is very specific and effective and differs in different pathogenic fungi and plant species due to the components of plant system. The article presents a critical review on the molecular association of PGIP with PG in nature. An insight has been provided for the use of PGIP in the extracellular localization of mature proteins, in the inhibition of fungal infection, as an elicitor of immune response in plants with great economic and agricultural importance across the world.
