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.

Ligand induced cleavage and nuclear localization of the rice XA21 immune receptor [PDF]

, 2012
The rice XA21 receptor confers immunity to the Gram-negative bacterial pathogen, _Xanthomonas oryzae_ pv. _oryzae_ (_Xoo_) upon recognition of the conserved microbial signature AxY^S^22.

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

Journal of Integrative Plant Biology, EarlyView.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.

Population genomic insights into variation and evolution of Xanthomonas oryzae pv. oryzae [PDF]

Scientific Reports, 2017
AbstractXanthomonas oryzae pv. oryzae ( Xoo) is a serious pathogen of rice causing bacterial leaf blight disease. Resistant varieties and breeding programs are being hampered by the emergence of highly virulent strains. Herein we report population based whole genome sequencing and analysis of 100 Xoo strains from India.

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

Rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae produces multiple DSF-family signals in regulation of virulence factor production [PDF]

, 2010
Background Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of rice bacterial blight disease. Xoo produces a range of virulence factors, including EPS, extracellular enzyme, iron-chelating siderophores, and type III-secretion dependent effectors ...

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.

VqLecRKV.4 and VqBAK1 Modulate Grapevine Resistance to Powdery Mildew by Regulating Dynamic Balance of ROS

Plant Biotechnology Journal, EarlyView.
ABSTRACT Grapevine powdery mildew, caused by the fungal pathogen Erysiphe necator, severely impacts plant growth and berry quality. However, the grapevine receptors and molecular mechanisms underlying grapevine resistance to E. necator remain poorly understood.

The Rice Cis‐Natural Antisense Transcript NAT1850 of Pri‐miR1850 Negatively Regulates Cold Tolerance by Repressing NPR3

Plant Biotechnology Journal, EarlyView.
ABSTRACT Natural antisense transcripts (NATs) correspond to nearly 60% of annotated rice loci, however their functions are largely unknown. In this study, we characterise a rice cis‐NAT (NAT1850) that completely overlaps with a rice‐specific primary miRNA, pri‐miR1850.
