Occurrence of Podosphaera xanthii Race 2 on Cucumis melo in Brazil
Plant Disease, 2004 Powdery mildew is an important disease of melons (Cucumis melo L.) cultivated in greenhouses in Brazil. Currently, there are 5 races of Podosphaera xanthii (formerly known as Sphaerotheca fuliginea) and 2 races of Golovinomyces cichoracearum (formerly known as Erysiphe cichoracearum) described on melons worldwide, but only race 1 of P.

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.The AA9 family protein ScAA9 of Stagonosporopsis cucurbitacearum plays dual roles as both a virulence factor for infection and a PAMP for host immune manipulation, highlighting the complexity of S. cucurbitacearum–host interactions. ABSTRACT Fungal pathogens secrete cell wall‐degrading enzymes that either act as virulence factors or are perceived by ...
