Action of Multiple Cell Wall–Degrading Enzymes Is Required for Elicitation of Innate Immune Responses During Xanthomonas oryzae pv. oryzae Infection in Rice

Molecular Plant-Microbe Interactions, 2016
Xanthomonas oryzae pv. oryzae secretes a number of plant cell wall–degrading enzymes (CWDEs) whose purified preparations induce defense responses in rice. These defense responses are suppressed by X. oryzae pv. oryzae using type 3 secretion system (T3SS)

Interactions of free-living amoebae with rice bacterial pathogens Xanthomonas oryzae pathovars oryzae and oryzicola. [PDF]

PLoS ONE, 2018
BACKGROUND:Free-living amoebae (FLA) are voracious feeders, consuming bacteria and other microbes during colonization of the phytobiome. FLA are also known to secrete bacteriocidal or bacteriostatic compounds into their growth environment.

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

The FEBS Journal, EarlyView.
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 ...

Penapisan aktinobakteria rhizosfer padi sebagai agens pengendali hayati Xanthomonas oryzae pv. oryzae pathogen penyebab penyakit hawar daun bakteri

Jurnal Agro, 2023
Bacterial leaf blight caused by X.o. pv. oryzae is an important disease of rice plants. Actinobacteria has potential as biological agents to control X.o. pv. oryzae because it has the ability to produce bioactive compounds.

Engineering the bacterial nutrition strategy to control plant diseases

Journal of Integrative Plant Biology, EarlyView.
This commentary on Wang et al. (2025) and Phan et al. (2025) highlights previously undiscovered Xanthomonas pathways for nutrition acquisition, explains how Xanthomonas bacteria hijack host molecular machinery through their effector proteins, and discusses how these studies can be used to develop new disease resistance mechanisms.

Xanthomonas oryzae pv. Oryzae Avirulence Genes Contribute Differently and Specifically to Pathogen Aggressiveness

Molecular Plant-Microbe Interactions, 2000
Genomic copies of three Xanthomonas oryzae pv. oryzae avirulence (avr) genes, avrXa7, avrXa10, and avrxa5, and four homologous genes, aB3.5, aB3.6, aB4.3, and aB4.5, were mutagenized individually or in combination to study the roles of avr genes in one ...

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 ...

The avrRxo1 Gene from the Rice Pathogen Xanthomonas oryzae pv. oryzicola Confers a Nonhost Defense Reaction on Maize with Resistance Gene Rxo1

Molecular Plant-Microbe Interactions, 2004
Maize lines that contain the single dominant gene Rxo1 exhibit a rapid hypersensitive response (HR) after infiltration with the rice bacterial streak pathogen Xanthomonas oryzae pv. oryzicola, but not with the rice bacterial blight pathogen X. oryzae pv.

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.
