Phytophthora infestans is the causal agent of the late potato blight disease and also infects tomatoes and other members of the Solanaceae. This oomycete caused several major crop losses including the Great Famine in Ireland.

Jan 1, 2014 · Phytophthora infestans is a destructive pathogen of potato and tomato, and a model system for oomycetes, a lineage of mostly filamentous eukaryotes related to diatoms and brown algae. P. infestans has had tremendous impacts on human history and is …

Infection of a transgenic plant expressing a CFP‐histone 2B fusion (cyan) by a Phytophthora infestans transformant secreting RXLR effector Pi22926‐mRFP fusion protein from haustoria. mRFP fluorescence (magenta) is detectable in the nucleus and nucleolus (arrow) of haustoriated cells indicating translocation has occurred.

Phytophthora infestans is a heterothallic oomycete, and it is a near‐obligate hemibiotrophic pathogen under natural and agricultural conditions. The asexual cycle (Fig. 1) enables dramatically rapid population growth in susceptible host tissue.

Apr 25, 2011 · Phytophtora infestans is an oomycete protist. P. infestans was originally thought to be a fungal species due to its filamentous structure and metabolic strategies, but recent biochemical and phylogenetic analyses has revealed that P. infestans is only remotely related to fungi and is more closely related to heterokont algae (12, 16).

Phytophthora infestans is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by Alternaria solani, is also often called "potato blight".

Jan 24, 2025 · We examined the evolutionary history of Phytophthora infestans and its close relatives in the 1c clade. We used whole genome sequence data from 69 isolates of Phytophthora species in the 1c clade and conducted a range of genomic analyses including nucleotide diversity evaluation, maximum likelihood trees, network assessment, time to most recent common ancestor and migration analysis. We ...

Nov 16, 2021 · This datasheet on Phytophthora infestans covers Identity, Overview, Distribution, Dispersal, Hosts/Species Affected, Diagnosis, Biology & Ecology, Seedborne Aspects, Natural Enemies, Impacts, Prevention/Control, Further Information.

Phytophthora infestans was first described by C. Montagne in France under the name Botrytis infestans and by the Reverend M. J. Berkeley in 1846 (Berkeley, 1846; Montagne, 1846). The pathogen caused the Irish potato famine.

With the arrival of new genotypes and increasing fungicide resistance, control of Phytophthora infestans continues to be a challenge. While fungal, bacterial and viral pathogens continue to shape global societies, there are few plant-specific pathogens that can be regarded as having impacted the 19th and 20th centuries in the way Phytophthora ...
