Hydroxyproline Enhancement as a Primary Event in the Successful Development of Erysiphe graminis in Wheat.
Host cell wall hydroxyproline enhancement was observed in the successful development of the parasite Erysiphe graminis DC. f. sp. tritici em Marchal (MS-1) on wheat (em Thell). Hydroxyproline enhancement, which was observed only in susceptible hosts, was detected as early as 25 hours after infection. This observation suggests that the increase in cell wall hydroxyproline is a primary event in the host-pathogen interaction of Erysiphe graminis in wheat.
