A plant natriuretic peptide-like gene in the bacterial pathogen Xanthomonas axonopodis may induce hyper-hydration in the plant host: a hypothesis of molecular mimicry

BMC Evolutionary Biology, 2004
Background Plant natriuretic peptides (PNPs) are systemically mobile molecules that regulate homeostasis at nanomolar concentrations. PNPs are up-regulated under conditions of osmotic stress and PNP-dependent processes include changes in ion transport ...

A stage‐dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean

Plant, Cell &Environment, Volume 49, Issue 7, Page 3500-3517, July 2026.
Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

A TALE of Transposition: Tn3-Like Transposons Play a Major Role in the Spread of Pathogenicity Determinants of Xanthomonas citri and Other Xanthomonads

mBio, 2015
Members of the genus Xanthomonas are among the most important phytopathogens. A key feature of Xanthomonas pathogenesis is the translocation of type III secretion system (T3SS) effector proteins (T3SEs) into the plant target cells via a T3SS.

CRISPR/Cas‐Mediated Gene Editing in Plant Immunity and Its Potential for the Future Development of Fungal, Oomycete, and Bacterial Pathogen‐Resistant Pulse Crops

Plant, Cell &Environment, Volume 49, Issue 7, Page 3573-3585, July 2026.
ABSTRACT Pulses provide myriad health benefits and are advantageous in an environmental context as a result of their leguminous nature. However, phytopathogenic fungi, oomycetes and bacteria pose a substantial threat to pulse production, at times leading to crop failure.

Draft genome sequences of xanthomonas sacchari and two banana-associated xanthomonads reveal insights into the xanthomonas group 1 clade

, 2013
NOTE: the published correction is in ORE at http://hdl.handle.net/10871/25734We present draft genome sequences for three strains of Xanthomonas species, each of which was associated with banana plants (Musa species) but is not closely related to the ...

Electron Transport Systems of Xanthomonas oryzae and Xanthomonas phaseoli

Journal of the agricultural chemical society of Japan, 1963
(1) イネ白葉桔病菌およびインゲン葉焼病菌菌体より音波破砕法により電子伝達系標品を得,これをコハク酸ソーダまたはNADHで緩徐に還元することにより,各チトクローム成分の変化を記録した.この結果,従来報告されているとおり,前者ではチトクロームa1およびb1,後者でばa1, a2およびb1の存在をみとめた以外に,両者とも微量のc成分を併存するがわかった. (2) これらのことより,この菌のアンチマイシンA非感受性はb→c系の欠損よりもむしろこのb→c間に存在する因子の質的相違に帰因するものと考えられる. (3) 前記標品はNADHを電子供与体として結晶酵母チトクロームcを還元するこるができる. (4)以上の事実その他をもとにして,暫定的な両菌の電子伝達系のschemeが提出された.

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

Advanced Science, Volume 13, Issue 32, 9 June 2026.
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 ...

Spatial distribution and biophysical relationships of common bean angular leaf spot (Pseudocercospora griseola) with agronomic factors in west and southwest Ethiopia

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract The prevalence of angular leaf spot (ALS) in common beans (Phaseolus vulgaris L.) poses significant challenges to productivity in the western and southwestern regions of Ethiopia. This agricultural study was conducted to assess the distribution of ALS and examine the relationship between ALS and biophysical and agronomic factors.

Defensin‐DNA Supramolecular Complexes as a New pH‐Sensing Nanomaterial

Aggregate, Volume 7, Issue 6, June 2026.
Crocodylus porosus β‐defensin 13 (CpoBD13), a host defence peptide from the saltwater crocodile, is discovered to interact with single‐ and double‐stranded DNA to form supramolecular assemblies, termed defensin‐induced spherical complexes (DISCs).
