Resistance Genes and their Interactions with Bacterial Blight/Leaf Streak Pathogens (Xanthomonas oryzae) in Rice (Oryza sativa L.)—an Updated Review

Rice, 2020
Rice (Oryza sativa L.) is a staple food crop, feeding more than 50% of the world’s population. Diseases caused by bacterial, fungal, and viral pathogens constantly threaten the rice production and lead to enormous yield losses.

Effect of rain simulation on Xanthomonas oryzae pv. oryzae population density in guttation fluid and on the spread of bacterial blight in rice [PDF]

, 2015
Bacterial blight of rice caused by Xanthomonas oryzae pv. oryzae is most serious biotic constraint of rice production in Punjab, influenced mainly by environmental factors and nutritional factors applied to the rice crop. Present study aimed at observing

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

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 ...

Phosphate starvation enhances Xanthomonas oryzae pv. oryzae resistance in rice

Biologia plantarum, 2023
Bacterial leaf blight (BLB) is a common disease that affects rice development and yield. The effects of major nutrients, especially nitrogen, on rice BLB susceptibility have been considered when devising rational fertilization strategies. However, the defense mechanism of rice against BLB under phosphate (Pi)-deficient conditions remains uncertain ...

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.

Leaf Eh and pH: A Novel Indicator of Plant Stress. Spatial, Temporal and Genotypic Variability in Rice (Oryza sativa L.) [PDF]

, 2019
A wealth of knowledge has been published in the last decade on redox regulations in plants. However, these works remained largely at cellular and organelle levels. Simple indicators of oxidative stress at the plant level are still missing. We developed a

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.
