Atypical antipsychotic drugs (APDs), all of which are relatively more potent as serotonin (5‐HT) 2A than dopamine D 2 antagonists, may improve negative symptoms and cognitive dysfunction in schizophrenia, part, via increasing cortical release. 5‐HT 1A agonism has been also suggested to contribute the ability increase The present study tested hypothesis that clozapine, olanzapine, risperidone, perhaps other atypical APDs, release rat medial prefrontal cortex (mPFC) receptor activation, a...
Between 1998 and 1999, control failure of powdery mildew (Podosphaera fusca) downy (Pseudoperonospora cubensis) by the strobilurin fungicides azoxystrobin kresoxim-methyl was observed in cucumber-growing areas Japan. Results from inoculation tests carried out on intact cucumber plants leaf disks clearly showed distribution pathogen isolates highly resistant to kresoximmethyl. Fragments fungicide-targeted mitochondrial cytochrome b gene were polymerase chain reaction amplified total DNA their...
Beneficial microbes in the microbiome of plant roots improve health. Induced systemic resistance (ISR) emerged as an important mechanism by which selected growth–promoting bacteria and fungi rhizosphere prime whole body for ...Read More
Recently in Japan, isolates resistant to boscalid, a succinate dehydrogenase inhibitor (SDHI), have been detected Corynespora cassiicola (Burk. & Curt.) Wei and Podosphaera xanthii (Castaggne) Braun Shishkoff, the pathogens causing leaf spot powdery mildew disease on cucumber, respectively. Resistant of C. are widely distributed represent serious problem control at present. Novel SDHI fungicides, including fluopyram, now under development.The growth very highly boscalid-resistant, sensitive...
Colletotrichum species cause anthracnose diseases on many plants and crops. A new generation of succinate dehydrogenase inhibitors (SDHIs) was developed recently. The inhibitory activity the five SDHI fungicides against determined in this study.Isolates C. gloeosporioides, acutatum, cereale orbiculare were insensitive (naturally resistant) to boscalid, fluxapyroxad fluopyram YBA agar medium. In contrast, these isolates relatively sensitive penthiopyrad, except for orbiculare. Most...
Fungicides have greatly contributed to sustaining quality food production through protecting a variety of crops from fungal diseases. However, such is often threatened by the occurrence pathogen strains resistant fungicides. In this paper, resistance QoI and MBI-D fungicides in pathogens horticultural rice blast fungus, respectively, are introduced as representative cases which been experienced recently. Implications for integrated disease control that reduces risk fungicide discussed, then...
A total of 618 isolates corynespora leaf spot fungus ( Corynespora cassiicola ) collected from 24 commercial cucumber greenhouses in 12 cities Ibaraki Prefecture, Japan, were tested for their sensitivity to boscalid. Boscalid‐resistant detected 17 out 19 with a history use this fungicide and detection frequencies the resistant exceeded 47% nine greenhouses. Frequencies very highly (VHR) 50% effective concentration (EC 50 values boscalid exceeding 30 μg mL −1 higher than those moderately (MR)...
ABSTRACT The molecular mechanism of QoI fungicide resistance was studied using isolates cucumber Corynespora leaf spot fungus (Corynespora cassiicola) and the eggplant mold (Mycovellosiella nattrassii). In both pathogens, a mutation at position 143 from glycine to alanine (G143A) detected in cytochrome b gene that encodes for fungicide-targeted protein. Moreover, nucleotide sequence amino acid converted GGT or GGA sensitive (wild-type) GCT GCA resistant (mutant-type) isolates. methods...

Evolved resistance to fungicides is a major problem limiting our ability control agricultural, medical and veterinary pathogens frequently associated with substitutions in the amino acid sequence of target protein. The convention for describing cite wild-type acid, codon number new using one-letter code. It has been observed that orthologous mutations have selected different species by from same mode action class, but acids numbers. These differences numbering arise lengths proteins each...
Anthracnose diseases of fruit crops are mainly caused by Colletotrichum gloeosporioides and C. acutatum. In these species, intra- interspecific variation in fungicide sensitivity has been reported; however, the relationship between molecular phylogeny not analyzed. Fifty-one isolates from 10 crops, acacia, tea were tested for their sensitivities to thiophanate-methyl, diethofencarb, iminoctadine-triacetate, internal transcribed spacer (ITS) 5.8S regions rDNA divided into sensitive, less...
In 2004, field isolates of Botrytis cinerea Pers. ex Fr., resistant to strobilurin fungicides (QoIs), were first found in commercial citrus orchards Wakayama Prefecture, Japan. Subsequently, QoI-resistant this fungus also detected plastic strawberry greenhouses Saga, Ibaraki and Chiba prefectures, Biological molecular characterisation was conducted study.QoI-resistant B. grew well on PDA plates containing kresoxim-methyl or azoxystrobin at 1 mg L(-1), supplemented with mM n-propyl gallate,...
ABSTRACT This study reports the mode of action acibenzolar-S-methyl (ASM) against Japanese pear scab, caused by Venturia nashicola. Pretreatment potted trees with ASM reduced scab symptoms and potentiated several lines plant defense response. included transcripts encoding polygalacturonase-inhibiting protein (PGIP) that were highly transiently promoted after inoculation plants pretreated ASM, suggesting a possible role for defenses involved in direct interaction pathogen. The activity key...
The accumulation of chitinase and its involvement in systemic acquired disease resistance was analyzed using acibenzolar-S-methyl salicylic acid (SA). Resistance against scab (pathogen: Cladosporium cucumerinum) the were rapidly induced cucumber plants after treatment with acibenzolar-S-methyl. In contrast, SA protected from C. cucumerinum only on treated leaves. response to inoculation pathogen more previously than pretreated or water. Thus, it appears that a prospective signal(s), induces...
