Historic Late Blight Outbreaks Caused by a Widespread Dominant Lineage of Phytophthora infestans (Mont.) de Bary
Phytophthora infestans (Mont.) de Bary, the causal agent of potato late blight, was responsible for the Irish potato famine of the 1840s. Initial disease outbreaks occurred in the US in 1843, two years prior to European outbreaks. We examined the evolutionary relationships and source of the 19th-century outbreaks using herbarium specimens of P. infestans from historic (1846-1970) and more recen...
متن کاملGenetic factors encoding resistance to late blight caused by Phytophthora infestans (Mont.) de Bary on the potato genetic map.
Late blight, a potato disease caused by Phytophthora infestans (Mont.) de Bary, is of great economic significance, and has been the subject of numerous research projects aimed at both introducing resistance to the disease into potato cultivars, and at unravelling the mechanisms and genes underlying this resistance. This report is on publications about mapping the resistance to P. infestans enco...
متن کاملEvaluation of treatment strategies of the late blight Phytophthora infestans in Nepal by population dynamics modelling
The late blight disease caused by the fungus Phytophthora infestans is a serious pest of solanaceous crops capable of destroying a complete harvest. Therefore it is heavily treated with fungicides, especially in areas where the knowledge among farmers about application and impacts of fungicides is generally low, as it is the case in Nepal. In order to derive efficient treatment strategies with ...
متن کاملCharacterization of the Potato Late Blight Pathogen Phytophthora infestans in Tunisia
This mini-review focus on summarizing different phenotypic and genotypic analysis recorded on Phytophthora infestans population collected from the Northern area of Tunisia. Here, we demonstrated that mating type distribution plays a primordial role in genetic structure of the pathogen between sampling regions. Also, a probably strong correlation between mating type and metalaxyl resistance coul...
متن کاملA Phytophthora infestans RXLR effector targets plant PP1c isoforms that promote late blight disease
Plant pathogens deliver effectors to alter host processes. Knowledge of how effectors target and manipulate host proteins is critical to understand crop disease. Here, we show that in planta expression of the RXLR effector Pi04314 enhances leaf colonization by Phytophthora infestans via activity in the host nucleus and attenuates induction of jasmonic and salicylic acid-responsive genes. Pi0431...
