Plants are susceptible to a limited number of pathogens. Most infections fail due to active defense or absence of compatibility. Many components of the plant's surveillance system and defense arsenal have been identified in the last decades. However, knowledge is limited on compatibility; in particular, the role of plant factors in the infection process. To gain insight into these processes, we...

Plant resistance proteins mediate pathogen recognition and activate innate immune responses to restrict pathogen proliferation. One common feature of these proteins is an NB-ARC domain. In this study, we characterized a gene encoding a protein with an NB-ARC domain from wild Chinese grapevine Vitis pseudoreticulata accession "Baihe-35-1," which was identified in a transcriptome analysis of the ...

Reliance of biotrophic pathogens on living plant tissues to propagate implies strong interdependence between host metabolism and nutrient uptake by the pathogen. However, factors determining host suitability and establishment of infection are largely unknown. We describe a loss-of-inhibition allele of ASPARTATE KINASE2 and a loss-of-function allele of DIHYDRODIPICOLINATE SYNTHASE2 identified in...

Abstract Background Golovinomyces cichoracearum (DC.) is the main pathogen for tobacco powdery mildew fungus disease. Its outbreaks often result in severe harvest losses yield and quality of tobacco. Artocarpus champeden rich prenylated flavonoids, which are important plant’s defensive strategies. With aim continuously exploring bioactive natural metabolites agricultural chemicals, chemical inv...

Plants of the cannabis (Cannabis sativa L., marijuana) strain ‘Chronic Ryder’, grown outdoors in Fraser Valley British Columbia (BC), displayed symptoms powdery mildew late July 2019. The disease progressed rapidly under cool, wet conditions to infect leaves, stems, shoot tips and inflorescences by early September. To identify pathogen, DNA was extracted from healthy diseased leaves subjected P...
