Loop-mediated isothermal amplification for detection of the tomato and potato late blight pathogen, Phytophthora infestans.
AIMS To design and validate a colorimetric loop-mediated isothermal amplification assay for rapid detection of Phytophthora infestans DNA. METHODS AND RESULTS Two sets of loop-mediated isothermal amplification (LAMP) primers were designed and evaluated for their sensitivity and specificity for P. infestans. ITSII primers targeted a portion of the internal transcribed spacer region of ribosoma...
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 کاملEarlier occurrence and increased explanatory power of climate for the first incidence of potato late blight caused by Phytophthora infestans in Fennoscandia
BACKGROUND Late blight (caused by Phytophthora infestans) is a devastating potato disease that has been found to occur earlier in the season over the last decades in Fennoscandia. Up until now the reasons for this change have not been investigated. Possible explanations for this change are climate alterations, changes in potato production or changes in pathogen biology, such as increased fitnes...
متن کاملHistoric 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 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...
