Near- to long-term measures to stabilize global wheat supplies and food security
The Ukraine–Russia war will impact global food security over months if not years. In the wake of COVID-19 and in the face of increasing climate change, we propose responses to a multi-layered global food crisi...

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 ...

Open AccessPhytophthora methylomes are modulated by 6mA methyltransferases and associated with adaptive genome regions
Filamentous plant pathogen genomes often display a bipartite architecture with gene-sparse, repeat-rich compartments serving as a cradle for adaptive evolution. The extent to which this two-speed genome archit...

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 ...

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 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...
