Thiazole, isothiazole, thiadiazole and their derivatives are widely thought to induce host defences against plant pathogens. In this article, we report that bismerthiazol, a molecule, reduces disease by inhibiting the histidine utilization (Hut) pathway quorum sensing (QS). Bismerthiazol provides excellent control of bacterial rice leaf blight (BLB) caused Xanthomonas oryzae pv. (Xoo), but does not greatly inhibit Xoo growth in vitro. According RNA-sequencing analysis, transcription Hut...
1,2,4-Triazole-1,3-disulfonamide derivatives as dual function inhibitors of mitochondrial complex II (SQR) and III (cyt<italic>bc</italic><sub>1</sub>) were discovered.
This study evaluated the use of phenamacril and ipconazole, alone in mixtures, for control rice bakanae disease caused by Fusarium fujikuroi. Mixtures were studied with goal reducing selection fungicide-resistant field isolates fungus. When tested alone, both ipconazole exhibited high antifungal activity against F. fujikuroi mycelial growth; average EC50 value 19 was 0.1544 μg/ml 0.0472 ipconazole. A 2:1 mixture a slightly synergistic (greater than additive) inhibition growth. Inhibition...
The point mutation at codon 200 (TTC→TAC, F200Y) confers moderate resistance to carbendazim in Sclerotinia sclerotiorum. This mutant genotype (F200Y) has been detected mainly by determining the minimum inhibitory concentration (MIC), which requires 3 5 days. Here, we developed a loop-mediated isothermal amplification (LAMP) assay for rapid detection of F200Y carbendazim-resistant isolates S. Specific LAMP primers were designed and concentrations components optimized. optimal reaction...
Mulberry (Morus alba L.) is an important cash crop and medicinal plant that has been cultivated for more than 5,000 years in China. The area of mulberry production Guangxi Province 45% total China, with 1.3 million ha planted. In recent years, a root rot occurred Heng County covering all the planting farms. Observations 200 diseased plants were made. xylem infected roots first turned brown, then became black followed by cortex rot. easily separated. stem symptomatic was also brown bark...
Rice bacterial leaf blight, caused by Xanthomonas oryzae pv. oryzae, and rice streak, X. oryzicola, are major diseases of rice. Phenazine-1-carboxylic acid (PCA) is a natural product that isolated from Pseudomonas spp. used to control many important in China. We previously reported PCA disturbs the redox balance, which results accumulation reactive oxygen species oryzae. In this study, we found significantly upregulated transcript levels catB katE, encode catalases, sensitivity was reduced...
Abstract Magnaporthe oryzae is one of the most destructive pathogens that threaten rice production around world. Previous studies mainly focus on pathogenic mechanism M. during infection at leaf stage. However, panicle tissue not well understood. In present study, we performed RNA sequencing (RNA-seq) to study gene expression patterns stage and stage, respectively. The differentially expressed genes (DEGs) in infected tissues were analyzed. Gene ontology (GO) enrichment analysis DEGs...
Rice false smut, caused by the plant pathogenic fungus Ustilaginoidea virens, is widespread in rice-growing regions globally, severely compromising rice quality and production. Employing Bacillus spp. to control smut represents an effective environmentally sustainable strategy for disease management. The lipopeptides produced velezensis Jt84 demonstrated robust inhibitory effects against U. resulting abnormal mycelial morphology spore germination. Iturins were identified as essential...
Xanthomonas oryzae pv. oryzae, which causes rice bacterial leaf blight, and oryzicola, streak, are important plant-pathogenic bacteria. A member of the adaptor protein family, ankyrin protein, has been investigated largely in humans but rarely In this study, a novel ankyrin-like AnkB, was identified X. oryzicola. The expression ankB significantly upregulated when these bacteria were treated with phenazine-1-carboxylic acid (PCA). is located 58 bp downstream gene catB (which encodes catalase)...
OxyR and SoxR are two transcriptional regulators in response to oxidative stress most bacteria, has been reported be activated by the endogenous redox-cycling compound phenazine phenazine-producing organisms. However, which regulator is pathogens treated with antibiotic phenazine-1-carboxylic acid (PCA) not determined. In this study, we found that PCA treatment rather than phytopathogenic bacteria Xanthomonas oryzae pv. X. oryzicola. We also was much more sensitive H 2 O had a defective...
The effects of the natural pesticides, phenazines, were reported to be limited by some tolerant metabolism processes within Xanthomonas. Our previous studies suggested that functional cytochrome bc1 complex, indispensable component respiration chain, might participate in tolerating phenazines In this study, mutants Xanthomonas campestris pv. (Xcc) and oryzae (Xoo), which exhibit different tolerance abilities constructed, complex was proven partake a critical conserved role addition, results...
Phenazine-1-carboxylic acid (PCA), a member of phenazines secreted by microorganisms, inhibits the growth many bacteria and fungi. Xanthomonas campestris pv. is causal agent black rot, most important disease cruciferous crops worldwide, more tolerant to PCA than other species. Previous studies reported that reactive oxygen species (ROS) scavenging ability involved in regulating tolerance Additionally, cytochrome c maturation (CCM) system has been found play role ROS system. In this study,...
Rice blast, caused by Pyricularia oryzae, is one of the most destructive rice diseases worldwide. It essential to understand population structure and race distribution P. oryzae for prevention control blast. This study collected 1584 isolates across Jiangsu province from 2003 2017 determine diversity, common dominant structures, resistance profiles using eight parameters Chinese differential cultivars (CDC) entries. Race diversity analysis indicated that in increased 2006 fluctuated steadily...
Rice blast disease, caused by the plant pathogenic fungus Magnaporthe oryzae ( M. ), severely constrains rice production worldwide. Biological control of using plant-associated microorganisms is an efficient and environmentally friendly approach to disease management. Bacillus bacteria produce a broad array antifungal lipopeptides, making them effective biological agents. In previous study, velezensis strain Jt84 exhibited biocontrol activity against compounds it produces were isolated acid...
Rice false smut (RFS), caused by Villosiclava virens, is an important fungal disease in panicles of rice. V. virens a heterothallic ascomycete controlled two opposite idiomorphs, MAT1-1 and MAT1-2. Previous study showed that sexual reproduction plays role the epidemic RFS. In this study, we developed loop-mediated isothermal amplification (LAMP) assay to detect mating type easily rapidly using specific primers based on genes MAT1-1-2 MAT1-2-1, respectively. The LAMP used only water/dry bath...
