Purification and characterization of proline/hydroxyproline-rich glycoprotein from pearl millet coleoptiles infected with downy mildew pathogen Sclerospora graminicola

A proline/hydroxyproline-rich glycoprotein that is induced in Pennisetum glaucum upon Sclerospora graminicola infection was purified from the plants' cell wall and biochemically characterized. Its involvement in oxidative cross-linking processes contributing to plants' defence reactions is supposable.
