Effector‐Mediated Spatial Reprogramming of Glycolate Oxidase Subverts Peroxisomal and Membrane‐Associated ROS Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...

Comparative genomics of a cannabis pathogen reveals insight into the evolution of pathogenicity in Xanthomonas

Frontiers in Plant Science, 2015
Pathogenic bacteria in the genus Xanthomonas cause diseases on over 350 plant species, including cannabis (Cannabis sativa L.). Because of regulatory limitations, the biology of the Xanthomonas-cannabis pathosystem remains largely unexplored.

An Auto‐Activated NLR‐Protein OsRGA3D605V Confers Rice Triple Resistance and Deactivates Resistance After Phosphorylation by OsILA1

Plant Biotechnology Journal, EarlyView.
ABSTRACT The incidence of pests and diseases seriously impacts rice production, and NLR genes play a crucial role in the regulation of immune signalling in rice. Here, we identified an NLR gene OsRGA3 that positively regulates rice resistance to brown planthopper (BPH) and rice blast disease (RBD).

A Bacterial Effector Hijacks NBR1 to Modulate Both Autophagy and Ubiquitination‐Mediated Degradation That Promotes Bacterial Infection

Plant Biotechnology Journal, EarlyView.
ABSTRACT Autophagy and the ubiquitin/26S proteasome system (UPS) play critical roles in the immune defence of the host against pathogen invasion. As a countermeasure, pathogens deploy effector proteins to subvert or hijack autophagy and UPS processes.

Pro‐Vitamin A Biofortified Cavendish Banana: Trait Stability in the Field

Plant Biotechnology Journal, EarlyView.
ABSTRACT Vitamin A deficiency (VAD), a major global health concern, has driven efforts to develop staple crops with enhanced pro‐vitamin A (pVA) content. Delivering meaningful nutritional benefits, however, requires technologies that maintain elevated carotenoid levels under field conditions. Previous proof‐of‐concept work demonstrated that pVA content

Plant disease complexes: Xanthomonas co-infections with multiple pathogens

Phytopathology Research
Xanthomonas is one of the most widespread and destructive bacterial plant pathogens, posing a significant threat to global food security. Xanthomonas pathovars exhibit remarkable host specificity and adaptability, and are capable of infecting a variety ...

The Wheat CRK‐RLCK‐MAPKs Signalling Module Confers High‐Temperature All‐Stage Resistance to Stripe Rust

Plant Biotechnology Journal, EarlyView.
ABSTRACT As global warming continues, rising temperatures significantly alter the interactions between wheat and the stripe rust pathogen Puccinia striiformis f. sp. tritici (Pst). Utilising high‐temperature all‐stage (HTAS) resistance to Pst is a novel strategy for breeding climate and disease resilient wheat cultivars.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Establishment of a system for screening and identification of novel bactericide targets in the plant pathogenic bacterium Xanthomonas oryzae pv. oryzae using Tn-seq and SPR

Journal of Integrative Agriculture
Xanthomonas spp. cause severe bacterial diseases. However, effective strategies for prevention and management of these diseases are scarce. Thus, it is necessary to improve the efficiency of control of diseases caused by Xanthomonas.

The Xanthomonas type IV pilus

Current Opinion in Microbiology, 2016
Type IV pili, a special class of bacterial surface filaments, are key behavioral mediators for many important human pathogens. However, we know very little about the role of these structures in the lifestyles of plant-associated bacteria. Over the past few years, several groups studying the extensive genus of Xanthomonas spp.
