Calcium signaling in plant defense

New Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

Variations in type III effector repertoires do not correlate with differences in pathological phenotypes and host range observed for Xanthomonas citri pv. citri pathotypes [PDF]

, 2012
Xanthomonas citri pv. citri (Xac) is a quarantine bacterium causing Asiatic citrus canker. Strains of Xac are classified as pathogenic variants i.e.

CRISPR/Cas9-targeted mutagenesis of Os8N3 in rice to confer resistance to Xanthomonas oryzae pv. oryzae

Rice, 2019
Genome editing tools are important for functional genomics research and biotechnology applications. Recently, the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein-9 (Cas9) system for gene knockout has emerged ...

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.

Nitrogen Sources Inhibit Biofilm Formation of Xanthomonas oryzae pv. oryzae

Journal of Microbiology and Biotechnology, 2018
Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial blight, which results in severe economic damage to rice farms. Xoo produces biofilms for pathogenesis and survival both inside and outside the host. Biofilms, which are important virulence factors, play a key role in causing the symptoms of Xoo infection.

Complete Genome Sequences of 10 Xanthomonas oryzae pv. oryzae Bacteriophages

Microbiology Resource Announcements, 2019
Xanthomonas oryzaepv. oryzae is the causative agent of bacterial leaf blight of rice. The application of bacteriophages may provide an effective tool against this bacterium. Here, we report the complete genome sequences of 10 newly isolated OP2-likeX. oryzaepv. oryzae bacteriophages.

Antagonistic Interactions Between Strains of Xanthomonas oryzae pv. oryzae [PDF]

Phytopathology®, 2003
The ability of some phytopathogenic bacterial strains to inhibit the growth of others in mixed infections has been well documented. Here we report that such antagonistic interactions occur between several wild-type strains of the rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae.

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 ...
