Mitotic Recombination and Rapid Genome Evolution in the Invasive Forest Pathogen Phytophthora ramorum

mBio, 2019
Invasive alien species often have reduced genetic diversity and must adapt to new environments. Given the success of many invasions, this is sometimes called the genetic paradox of invasion.

Metabolomic Analysis of Phytophthora parasitica Growth in the Presence of β‐sitosterol Indicates Adaptive Mechanisms Modulated by Sterols [PDF]

J Basic Microbiol
ABSTRACT Phytophthora parasitica is a generalist phytopathogenic oomycete that infects a series of crops with great economic interest, including tomato, tobacco, and citrus species. Sterols are essential lipids in eukaryotic organisms, playing a fundamental role in the structure and function of the cell membrane.

Exploring nucleo-cytoplasmic large DNA viruses in Tara Oceans microbial metagenomes [PDF]

, 2013
Nucleo-cytoplasmic large DNA viruses (NCLDVs) constitute a group of eukaryotic viruses that can have crucial ecological roles in the sea by accelerating the turnover of their unicellular hosts or by causing diseases in animals. To better characterize the

Molecular Genetics of Pathogenic Oomycetes [PDF]

Eukaryotic Cell, 2003
Parasitic and pathogenic lifestyles have evolved repeatedly in eukaryotes ([93][1]). Several parasitic eukaryotes represent deep phylogenetic lineages, suggesting that they feature unique molecular processes for infecting their hosts. One such group is formed by the oomycetes.

Calcium signaling in plant defense

New Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

How to Unravel the Key Functions of Cryptic Oomycete Elicitin Proteins and Their Role in Plant Disease

Plants, 2021
Pathogens and plants are in a constant battle with one another, the result of which is either the restriction of pathogen growth via constitutive or induced plant defense responses or the pathogen colonization of plant cells and tissues that cause ...

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

New Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.

Phytophthora megakarya and Phytophthora palmivora, closely related causal agents of cacao black pod rot, underwent increases in genome sizes and gene numbers by different mechanisms [PDF]

, 2017
Phytophthora megakarya (Pmeg) and Phytophthora palmivora (Ppal) are closely related species causing cacao black pod rot. Although Ppal is a cosmopolitan pathogen, cacao is the only known host of economic importance for Pmeg.

Challenges facing the management of pesticide resistance in weeds, diseases and insect pests in European agriculture and the future of effective IPM implementation

Pest Management Science, EarlyView.
Opinion on pesticide resistance and management in the European Union (EU) and United Kingdom (UK) is presented cognisant of changes in regulation that impact on mode of action availability and cropping system choice. Abstract In recent times, pesticide resistance has been managed reasonably effectively, either proactively or reactively, by monitoring ...

Invertases in Phytophthora infestans Localize to Haustoria and Are Programmed for Infection-Specific Expression

mBio, 2020
The oomycete Phytophthora infestans, the causal agent of potato and tomato blight, expresses two extracellular invertases. Unlike typical fungal invertases, the P.
