Plant Biotechnology Journal, EarlyView.ABSTRACT Plant immune systems recognise pathogen‐derived molecular patterns to activate defence responses, yet the mechanisms underlying fungal pattern recognition in crops remain largely unclear. Here, we characterise the cysteine‐rich secretory protein SsSCP from the broad‐host‐range fungal pathogen Sclerotinia sclerotiorum as a potent elicitor of ...

Transgenic expression of the dicotyledonous pattern recognition receptor EFR in rice leads to ligand-dependent activation of defense responses [PDF]
, 2015 Plant plasma membrane localized pattern recognition receptors (PRRs) detect extracellular pathogen-associated molecules. PRRs such as Arabidopsis EFR and rice XA21 are taxonomically restricted and are absent from most plant genomes.

Plant Biotechnology Journal, EarlyView.ABSTRACT Bacterial blight (BB) of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the major drivers of yield losses in Africa and Asia. Xoo secretes TAL‐effectors (TALe) that induce host SWEET sucrose uniporter by binding to the effector binding element (EBE) of SWEET promoters, likely required for Xoo reproduction and virulence.

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.

Deciphering small molecules as new virulence factors in the bacterial sugarcane pathogen Xanthomonas albilineans [PDF]
, 2010 Xanthomonas albilineans is a xylem-invading plant pathogen that causes leaf scald disease of sugarcane. Unlike most plant pathogenic bacteria, X. albilineans does not possess a Hrp-Type Three Secretion System. Pathogenicity of this bacterial species must

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.

De Novo Design and Synthesis of Novel Benzoxazinone Derivatives Targeting Dihydroxyacid Dehydratase
Plant Biotechnology Journal, EarlyView.ABSTRACT Dihydroxyacid dehydratase (DHAD), a key enzyme in the branched‐chain amino acid (BCAA) synthesis pathway, is a promising herbicide target. Currently, no commercial herbicides target DHAD, and no inhibitors are in development. Structural analysis suggests that coordination with iron–sulfur clusters and hydrophobic interactions with Tyr215 and ...

Why genes evolve faster on secondary chromosomes in bacteria [PDF]
, 2010 In bacterial genomes composed of more than one chromosome, one replicon is typically larger, harbors more essential genes than the others, and is considered primary.

Leaf Eh and pH: A Novel Indicator of Plant Stress. Spatial, Temporal and Genotypic Variability in Rice (Oryza sativa L.) [PDF]
, 2019 A wealth of knowledge has been published in the last decade on redox regulations in plants. However, these works remained largely at cellular and organelle levels. Simple indicators of oxidative stress at the plant level are still missing. We developed a
