Regulatory network of hrp gene expression in Xanthomonas oryzae pv. oryzae

Journal of General Plant Pathology, 2014
Like other plant-pathogenic bacteria, Xanthomonas oryzae pv. oryzae, the causal agent of bacterial leaf blight of rice, has hrp genes that are indispensable for its virulence. The hrp genes are involved in the construction of the type III secretion (T3S) apparatus, through which dozens of virulence-related proteins, called effectors, are directly ...

Isolation and Disease Assessment of Xanthomonas Oryzae Pv. Oryzae From Java Island and Pathogenic Assay on Near Isogenic Lines with Different Resistant Genes [PDF]

, 2014
Bacterial leaf blight disease caused by Xanthomonas oryzae pv oryzae (Xoo) is one of the important bacterial diseases,which is very destructive to rice plant. In this study, seventy isolates of Xoo were collected from several regions inWest Java, Central

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, Volume 293, Issue 9, Page 2772-2793, May 2026.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Evolution of Xanthomonas Gene Content: Gene Gain/Loss History and Species Divergence

Journal of Integrative Agriculture, 2012
Horizontal gene transfer (HGT) plays key roles in the evolution of pathogenetic bacteria, especially in pathogenetic associated genes. In this study, the evolutionary dynamics of Xanthomonas at species level were determined by the comparative analysis of

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

Plant Biotechnology Journal, Volume 24, Issue 5, Page 2988-3008, May 2026.
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, Volume 24, Issue 5, Page 2939-2955, May 2026.
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.

Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

Plant, Cell &Environment, Volume 49, Issue 5, Page 2516-2530, May 2026.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Role of an In Planta-Expressed Xylanase of Xanthomonas oryzae pv. oryzae in Promoting Virulence on Rice

Molecular Plant-Microbe Interactions, 2005
Xanthomonas oryzae pv. oryzae is the causal agent of bacterial leaf blight, a serious disease of rice. We demonstrated earlier that the type II secretion system (T2S) is important for virulence of X. oryzae pv. oryzae and that several proteins, including
