Cucurbit powdery mildew (CPM) is mainly caused by two obligate ectoparasites, Golovinomyces orontii s.l. (Go) and Podosphaera xanthii (Px), that are highly variable in virulence. Various independent systems of CPM race determination and denomination have been used in recent decades. We recently developed new tools to enhance research of CPM virulence variation. Diversity models were […]

Aphid-Triggered Immunity in Melon / Key Determinants for Durable Resistance to Virus and Aphids Nathalie Boissot INRA-GAFL, Montfavet, 84143, France The Vat gene in melon is unique in conferring resistance to both A. gossypii and the viruses it transmits. This double phenotype is controlled by […]

Podosphaera xanthii but not Golovinomyces cichoracearum infects Cucurbits in a Greenhouse at Salinas, California
Cosme Bojorques Ramos Karunakaran Maruthachalam, James D. McCreight Raymundo S. Garcia Estrada Traditionally, Erysiphe cichoracearum (now Golovinomyces cichoracearum) and Podosphaera xanthii, formerly Sphaerotheca fuliginea, have been reported as the causal agents of cucurbit powdery mildew (CPM) (2, 10). These two fungal species have often been misidentified (12), due to similarities in their anamorphic characteristics and […]
