The overlapping continuum of host range among strains in the Pseudomonas syringae complex

The overlapping continuum of host range among strains in the Pseudomonas syringae complex

Pseudomonas syringae is the most frequently emerging group of plant pathogenic bacteria. Because this bacterium is ubiquitous as an epiphyte and on various substrates in non-agricultural settings, there are many questions about how to assess the risk for plant disease posed by strains in the...

Non-TAL Effectors From Xanthomonas oryzae pv. oryzae Suppress Peptidoglycan-Triggered MAPK Activation in Rice

Non-TAL Effectors From Xanthomonas oryzae pv. oryzae Suppress Peptidoglycan-Triggered MAPK Activation in Rice

Xanthomonas oryzae pv. oryzae, the causal pathogen of bacterial blight of rice, depends on its type III secretion system and associated effector proteins to grow and colonize the vascular tissues of rice plants. The type III effectors include a family of closely related transcription activator-like...

A kiwellin disarms the metabolic activity of a secreted fungal virulence factor

A kiwellin disarms the metabolic activity of a secreted fungal virulence factor

Fungi-induced plant diseases affect global food security and plant ecology. The biotrophic fungus Ustilago maydis causes smut disease in maize (Zea mays) plants by secreting numerous virulence effectors that reprogram plant metabolism and immune responses. The secreted fungal chorismate mutase Cmu1...

Plant viruses transmitted in two different modes produce differing effects on small RNA-mediated processes in their aphid vector

Plant viruses transmitted in two different modes produce differing effects on small RNA-mediated processes in their aphid vector

Transmission of plant viruses by aphids involves multi-trophic interactions among host plants, aphid vectors, and plant viruses. Here, we used small RNA (sRNA) sequencing to visualize the sRNA response of Myzus persicae to two plant viruses that M. persicae transmits in different modes: the...

TALE‐carrying bacterial pathogens trap host nuclear import receptors for facilitation of infection of rice

TALE‐carrying bacterial pathogens trap host nuclear import receptors for facilitation of infection of rice


Many plant‐pathogenic Xanthomonas rely on the secretion of virulence transcription activator‐like effector (TALE) proteins into plant cells to activate plant susceptibility genes to cause disease. The process is dependent on the binding of TALEs to specific elements...

Trichoderma Species: Versatile Plant Symbionts

Trichoderma Species: Versatile Plant Symbionts

Because of the need to provide food for the growing population, agricultural activity is faced with the huge challenge of counteracting the negative effects generated by adverse environmental factors and diseases caused by pathogens on crops, while avoiding environmental pollution due to the...

The AMSH3 ESCRT-III-Associated Deubiquitinase Is Essential for Plant Immunity

The AMSH3 ESCRT-III-Associated Deubiquitinase Is Essential for Plant Immunity

Plant “nucleotide-binding leucine-rich repeat” receptor proteins (NLRs) detect alterations in host targets of pathogen effectors and trigger immune responses. The Arabidopsis thaliana mutant pen1 syp122 displays autoimmunity, and a mutant screen identified the deubiquitinase “associated...
