A complex resistance locus in Solanum americanum recognizes a conserved Phytophthora effector
Late blight caused by Phytophthora infestans greatly constrains potato production. Many Resistance (R) genes were cloned from wild Solanum species and/or introduced into potato cultivars by breeding. However, ind...

Open AccessDifferential loss of effector genes in three recently expanded pandemic clonal lineages of the rice blast fungus
Understanding the mechanisms and timescales of plant pathogen outbreaks requires a detailed genome-scale analysis of their population history. The fungus Magnaporthe (Syn. Pyricularia) oryzae—the causal agent of ...

Article
A resistosome-activated ‘death switch’
Pathogen perception triggers a monomeric nucleotide-binding leucine-rich plant immune receptor to form a pentameric wheel-like complex termed a resistosome, with the N-terminal α helices forming a funnel-shape...

Article
Old fungus, new trick
A secreted effector from the plant pathogenic fungus Ustilago maydis has evolved to acquire a new function that contributes to the unique lifestyle of this species, highlighting the utility of using comparative g...

Publisher Correction: Polymorphic residues in rice NLRs expand binding and response to effectors of the blast pathogen
In the version of this Article originally published, in Fig. 1b the single-letter code for the amino acid polymorphism at position 46 in the schematic of the AVR-PikE variant was incorrectly given as ‘H’. The ...

Polymorphic residues in rice NLRs expand binding and response to effectors of the blast pathogen
Accelerated adaptive evolution is a hallmark of plant–pathogen interactions. Plant intracellular immune receptors (NLRs) often occur as allelic series with differential pathogen specificities. The determinants...

Open AccessGene expression polymorphism underpins evasion of host immunity in an asexual lineage of the Irish potato famine pathogen
Outbreaks caused by asexual lineages of fungal and oomycete pathogens are a continuing threat to crops, wild animals and natural ecosystems (Fisher MC, Henk DA, Briggs CJ, Brownstein JS, Madoff LC, McCraw SL, ...

Open AccessGenome analysis of the foxtail millet pathogen Sclerospora graminicola reveals the complex effector repertoire of graminicolous downy mildews
Downy mildew, caused by the oomycete pathogen Sclerospora graminicola, is an economically important disease of Gramineae crops including foxtail millet (Setaria italica). Plants infected with S. graminicola are g...

Open AccessGenome sequencing of the staple food crop white Guinea yam enables the development of a molecular marker for sex determination
Root and tuber crops are a major food source in tropical Africa. Among these crops are several species in the monocotyledonous genus Dioscorea collectively known as yam, a staple tuber crop that contributes enorm...

Open AccessCan a biologist fix a smartphone?—Just hack it!
Biological systems integrate multiscale processes and networks and are, therefore, viewed as difficult to dissect. However, because of the clear-cut separation between the software code (the information encode...

Open AccessAlbugo-imposed changes to tryptophan-derived antimicrobial metabolite biosynthesis may contribute to suppression of non-host resistance to Phytophthora infestans in Arabidopsis thaliana
Plants are exposed to diverse pathogens and pests, yet most plants are resistant to most plant pathogens. Non-host resistance describes the ability of all members of a plant species to successfully prevent col...

Open AccessEmergence of wheat blast in Bangladesh was caused by a South American lineage of Magnaporthe oryzae
In February 2016, a new fungal disease was spotted in wheat fields across eight districts in Bangladesh. The epidemic spread to an estimated 15,000 hectares, about 16 % of the cultivated wheat area in Banglade...

Article
Fungal pathogenesis: Host modulation every which way
The plant pathogenic fungus Fusarium oxysporum secretes an effector that is similar to a plant peptide hormone, underscoring the variety of mechanisms that plant pathogens have evolved to tamper with host physiol...

Article
Open AccessHost specialization of the blast fungus Magnaporthe oryzae is associated with dynamic gain and loss of genes linked to transposable elements
Magnaporthe oryzae (anamorph Pyricularia oryzae) is the causal agent of blast disease of Poaceae crops and their wild relatives. To understand the genetic mechanisms that drive host sp...

Open AccessGenome analyses of the sunflower pathogen Plasmopara halstedii provide insights into effector evolution in downy mildews and Phytophthora
Downy mildews are the most speciose group of oomycetes and affect crops of great economic importance. So far, there is only a single deeply-sequenced downy mildew genome available, from Hyaloperonospora arabidops...

Open AccessGenome analyses of the wheat yellow (stripe) rust pathogen Puccinia striiformis f. sp. triticireveal polymorphic and haustorial expressed secreted proteins as candidate effectors
Wheat yellow (stripe) rust caused by Puccinia striiformis f. sp. tritici (PST) is one of the most devastating diseases of wheat worldwide. To design effective breeding strategies that maximize the potential for d...
