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 ...

OsRALF26 Serves as an Endogenous Signal Recognised by XA21 to Promote Robust and Distal Resistance in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant immune receptors detect both microbe‐derived and endogenous signals to activate defences. XA21, a rice immune receptor, confers strong race‐specific resistance to a subset of Xanthomonas oryzae pv. oryzae (Xoo) strains by recognising the microbial sulphated peptide RaxX.

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.

ZmWRKY29 Transcriptionally Represses ZmRBOHC to Attenuate ROS Production and Facilitates Gibberella Stalk Rot Susceptibility in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Gibberella stalk rot (GSR), caused by the fungal pathogen Fusarium graminearum, severely threatens maize production. However, the molecular mechanisms underlying maize resistance to GSR remain poorly understood. Here, we have identified ZmWRKY29 as a transcriptional repressor induced by F.

Identification of a Susceptibility Gene for Xanthomonas oryzae pv. oryzae in Vietnamese Elite Rice (Oryza sativa L.) Cultivar Bacthom 7

Plant Breeding, EarlyView.
ABSTRACT Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of bacterial leaf blight (BLB) disease in rice, exerting a detrimental impact on the yield of various rice cultivars in Vietnam, notably the Bacthom 7 (BT7) variety. Xoo possesses transcription activator‐like effectors (TALEs) which modulate the expression of host genes by specifically ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

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

Plant, Cell &Environment, EarlyView.
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.

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, EarlyView.
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.

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.

The structural diversity of xanthomonadin aryl polyenes and functional analysis of the genes required for their synthesis by Xanthomonas phytopathogens

Phytopathology Research
Xanthomonas is a genus of plant-associated Gram-negative bacteria which infect more than 400 plant species. A characteristic feature of Xanthomonas bacteria is the production of yellow membrane-bound pigments called xanthomonadins.
