The plant genes required for the growth and reproduction of plant pathogens are largely unknown. In an effort to identify these genes, we isolated Arabidopsis mutants that do not support the normal growth of the powdery mildew pathogen Erysiphe cichoracearum. Here, we report on the cloning and characterization of one of these genes, PMR6. PMR6 encodes a pectate lyase-like protein with a novel C...

Abstract Background Powdery mildew is a common leaf disease of crops worldwide. A large quantity chemical fungicides used to control this in horticulture and agriculture, producing serious safety environmental problems. To suppress safe environment-friendly ways, the biocontrol self-isolated new strain Lysobacter enzymogenes (CQ18) was studied against flue-cured tobacco powdery mildews. Results...

the erysiphaceae are obligatory parasitic fungi that cause powdery mildew disease of green space plants. during this study, powdery mildew fungi were collected and identified from different localities of ardabil landscape, iran. erysiphe rayssiae (on spartium junceum), erysiphe robiniae var. robiniae (on robinia pseudoacacia) and euoidium cf. agerati (on ageratum houstonianum)are new records fo...

Abstract Grapevine powdery mildew is caused by Erysiphe necator that seriously harms grape production in the world. Stilbene synthase makes phytoalexins contribute to resistance of grapevine against mildew. A novel VqNSTS3 was identified and cloned from Chinese wild Vitis quinquangularis accession Danfeng-2. Novel transferred into susceptible ‘Thompson Seedless’ Agrobacterium-mediated transform...

In recent years, some organism species are appearing popularly in the tobacco Cao Bang province, Vietnam, and caused severe damage to yield quality such as budworm (Helicoverpa assulta Guene), aphid (Myzus persicea Sulzer), powdery mildew (Erysiphe cichoracearum D.C). To manage them effectively, forecasting controlling insect pests play an important role cultivation. The predictive model was bu...

Powdery mildew disease, caused by Erysiphe cichoracearum, is considered one of the most severe pathogenic threats sunflower worldwide. This study discusses how to improve effect biocontrol agents, as a more economic and eco-friendlier alternative fungicides, mixing different bioagents (Trichoderma harzianum Bacillus subtilis) with antioxidants (ascorbic acid salicylic acid), either individually...
