Long considered intractable organisms by fungal genetic research standards, the oomycetes have recently moved to the centre stage of research on plant-microbe interactions. Recent work on oomycete effector evolution, trafficking and function has led to major conceptual advances in the science of plant pathology. In this review, we provide a historical perspective on oomycete genetic research an...
Oomycetes constitute an important agricultural pathogen for plants of the Solanaceae family. Black shank, caused by Phytophthora parasitica var. nicotianae, is one of the most important diseases affecting tobacco plantations in Cuba and worldwide, constituting an occasional cause of major economic losses. We have constructed a subtractive library with the aim of identifying tobacco genes involv...
While most commonly associated with prokaryotes, horizontal gene transfer (HGT) can also have a significant influence on the evolution of microscopic eukaryotes. Systematic analysis of HGT in the genomes of the oomycetes, filamentous eukaryotic microorganisms in the Stramenopiles-Alveolates-Rhizaria (SAR) supergroup, has to date focused mainly on intradomain transfer events between oomycetes an...
Oomycetes form a phylogenetically distinct group of eukaryotic microorganisms that include some the most notorious pathogens plants and animals. Through deployment remarkably diverse array effector proteins, oomycete succeed to overcome host defences cause infection. Effectors can operate extracellularly or enter living cells where they target subcellular compartments. Genome sequence informati...
Biotrophic eukaryotic plant pathogens require a living host for their growth and form an intimate haustorial interface with parasitized cells. Evolution to biotrophy occurred independently in fungal rusts and powdery mildews, and in oomycete white rusts and downy mildews. Biotroph evolution and molecular mechanisms of biotrophy are poorly understood. It has been proposed, but not shown, that ob...
