The Voyages of a Potato Companion: Phytophthora Infestans

Anthropocenes – Human, Inhuman, Posthuman, 2023
Accompanying a shipment of potatoes in 1845, a fungus-like traveller unintentionally made it to Europe, after having maintained a low profile for centuries in Latin America. Decades later, scientists identified this stowaway as the basic ingredient for an outbreak of potato late blight and gave it a name—Phytophthora infestans.

Effector Repertoire of Phytophthora betacei: In Search of Possible Virulence Factors Responsible for Its Host Specificity

Frontiers in Genetics, 2020
Phytophthora betacei is an oomycete plant pathogen closely related to Phytophthora infestans. It infects tree tomato (Solanum betaceum) in northern South America, but is, under natural conditions, unable to infect potatoes or tomatoes, the main hosts of ...

Variation in capsidiol sensitivity between Phytophthora infestans and Phytophthora capsici is consistent with their host range. [PDF]

PLoS ONE, 2014
Plants protect themselves against a variety of invading pathogenic organisms via sophisticated defence mechanisms. These responses include deployment of specialized antimicrobial compounds, such as phytoalexins, that rapidly accumulate at pathogen ...

The plant pathogen Phytophthora andina emerged via hybridization of an unknown Phytophthora species and the Irish potato famine pathogen, P. infestans. [PDF]

PLoS ONE, 2011
Emerging plant pathogens have largely been a consequence of the movement of pathogens to new geographic regions. Another documented mechanism for the emergence of plant pathogens is hybridization between individuals of different species or subspecies ...

Rapid detection of potato late blight using a loop-mediated isothermal amplification assay

Journal of Integrative Agriculture, 2020
Potato late blight caused by Phytophthora infestans is one of the most destructive plant diseases that threaten global food security. Early and effective diagnosis of P. infestans is required before disease management decisions are made.

A Global Marker Database for Phytophthora infestans [PDF]

Plant Disease, 1998
A marker database was compiled for isolates of the potato and tomato late blight pathogen, Phytophthora infestans, originating from 41 locations which include 31 countries plus 10 regions within Mexico. Presently, the database contains information on 1,776 isolates for one or more of the following markers: restriction fragment length polymorphism ...

Comparisons of Ribosomal Protein Gene Promoters Indicate Superiority of Heterologous Regulatory Sequences for Expressing Transgenes in Phytophthora infestans. [PDF]

PLoS ONE, 2015
Molecular genetics approaches in Phytophthora research can be hampered by the limited number of known constitutive promoters for expressing transgenes and the instability of transgene activity.

Molecular aspects of the potato — Phytophthora infestans interaction [PDF]

Netherlands Journal of Plant Pathology, 1992
The fungal pathogenPhytophthora infestans is the causal organism of late blight, one of the most devastating diseases of potato. In the past, various aspects of the potato-P. infestans interaction have been studied extensively. In this paper we briefly review the current knowledge of the molecular events associated with the interaction and in addition ...

THE EPIDEMIOLOGY OF PHYTOPHTHORA INFESTANS

Annals of Applied Biology, 1960
Of 3260 blighted tubers planted as seed in 5 successive years (1954‐8), twenty‐one produced stems invaded from below ground by Phytophthora infestans (0.79 and 0.52% respectively of those infected artificially and naturally). Only in 1955 was no stem found to be invaded, in every other year they started epidemics in experimental plots.
