Identification of Gene Responsible for Conferring Resistance against Race KN2 of Podosphaera xanthii in Melon. [PDF]

Int J Mol Sci
Powdery mildew caused by Podosphaera xanthii is a serious fungal disease which causes severe damage to melon production. Unlike with chemical fungicides, managing this disease with resistance varieties is cost effective and ecofriendly. But, the occurrence of new races and a breakdown of the existing resistance genes poses a great threat.

First report of the powdery mildew Podosphaera xanthii on Gynura bicolor [PDF]

Australasian Plant Disease Notes, 2015
In April–May 2015, powdery mildew was observed on stems and leaves of hongfengcai (Gynura bicolor), a perennial vegetable crop, in central Taiwan. Morphological and molecular characteristics determined this fungus as Podosphaera xanthii, which is reported on the plant genus Gynura for the first time.

Phospholipid production and signaling by a plant defense inducer against Podosphaera xanthii is genotype-dependent. [PDF]

Hortic Res
Abstract Biotrophic phytopathogenic fungi such as Podosphaera xanthii have evolved sophisticated mechanisms to adapt to various environments causing powdery mildews leading to substantial yield losses. Today, due to known adverse effects of pesticides, development of alternative control means is crucial and can be achieved by combining ...

Brazilian melon landraces resistant to Podosphaera xanthii are unique germplasm resources [PDF]

Annals of Applied Biology, 2017
Podosphaera xanthii is the most important causal agent of powdery mildew in melon, a crop ranked within the most economically important species worldwide. The best strategy to face this fungus disease, which causes important production losses, is the development of genetically resistant cultivars.

Deciphering the molecular basis of Podosphaera xanthii - cucurbits interaction

, 2019
Los cambios en fotosíntesis parecen venir mediados por la lucha en la obtención/limitación de nutrientes durante la infección de P. xanthii, mientras que los cambios en el metabolismo secundario se basan en el bloqueo de ciertas rutas metabólicas relacionadas directamente con las defensas de la planta.
