Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

PhyA, a Secreted Protein of Xanthomonas oryzae pv. oryzae, Is Required for Optimum Virulence and Growth on Phytic Acid as a Sole Phosphate Source

Molecular Plant-Microbe Interactions, 2003
Xanthomonas oryzae pv. oryzae causes bacterial leaf blight, a serious disease of rice. We have identified a novel virulence deficient mutant (BXO1691) of X. oryzae pv.

A Malian Rice Seed Endophyte Bacteria Control Efficiently the Growth of Xanthomonas oryzae pv oryzae and Xanthomonas oryzae pv oryzicola

South Asian Journal of Research in Microbiology, 2023
Aims: In Mali, rice (Oryza sativa L.) is a very important cereal in the food system and important losses in rice production are caused by bacterial diseases. Despite the important rice losses in production and the proven ability of some bacteria to control rice pathogens, in Mali very few studies have been carried out in biocontrol.

Botanical treatment enhances biochemical responses in enset (Ensete ventricosum (Welw.) Cheesman) clones

JSFA reports, EarlyView.
Abstract Background Bacterial wilt of enset (Ensete ventricosum (Welw.) Cheesman) is a severe disease caused by Xanthomonas campestris pv. musacearum, resulting in complete crop failure and considerable damage. This study assessed the biochemical responses of two enset clones (one resistant and one susceptible) when inoculated with the pathogen and ...

Recent Progress in Rice–Xanthomonas oryzae Interactions

Biology
Rice bacterial blight (BB) and bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), respectively, are among the most devastating bacterial diseases threatening global rice production.

Mutagenesis of 18 Type III Effectors Reveals Virulence Function of XopZPXO99 in Xanthomonas oryzae pv. oryzae

Molecular Plant-Microbe Interactions, 2010
Xanthomonas oryzae pv. oryzae depends on a type III secretion system (T3SS) to translocate effectors into host cells for its ability to cause bacterial blight of rice. All type III (T3) effectors with known function in X. oryzae pv.

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

New Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

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.

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 ...

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 ...
