Furthermore, coprinolide exhibited fungicidal activity against the tested fungi by inhibiting conidial germination to conidial death as confirmed by fluorescence microscopy using fluorescein diacetate and propidium iodide.

We investigated the impact of pyriofenone on the infection processes and cytological features of Blumeria graminis f. sp. tritici on wheat leaves. The preventive application of pyriofenone before inoculation did not inhibit conidial germination but effectively suppressed both appressorial and haustorial formation. Notably, haustorial formation was effectively inhibited, resulting in the complete suppression of successive lesion development and sporulation. Curative application of pyriofenone after inoculation also inhibited lesion expansion and sporulation. Furthermore, it had considerable impact on the morphogenesis of powdery mildew fungus. We observed multi-formed secondary appressoria, shrunken or bifurcated hyphae, abnormal conidiophores, and clubbed conidia-like structures. Subsequently, we employed a histochemical approach to analyze the localization of essential components for the polar growth of fungal hyphae. Pyriofenone induced mislocalization of the actin cytoskeleton, β-glucan and cytoplasmic vesicles, although it did not affect tubulin orientation.\u0000\u0000<img alt=\"\" src=\"https://www.jstage.jst.go.jp/pub/jpestics/advpub/0/advpub_D24-005/figure/advpub_D24-005.png\"/>\u0000Fullsize Image","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"8 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only one fungal species for the antifungal activity of 1 has been revealed, and details of the antifungal activity against other pathogenic fungus remain unknown. After extensive screening for antifungal activity, we found that 1 exhibits broad antifungal activity against pathogenic plant fungi, including Colletotrichum gloeosporioides, Botrytis cinerea, Pyricularia oryzae, Leptosphaeria maculans, and Rhizoctonia solani. Furthermore, we synthesized 12 derivatives from 1 and evaluated their antifungal activity to reveal the detailed structure-activity relationship.

The positive regulation of plant disease resistance by SLs has recently been demonstrated by analyses using SL-related mutants. In Arabidopsis, SL-mediated signaling has been reported to modulate salicylic acid-mediated disease resistance, in which the priming of plant immunity plays an important role. In this study, we analyzed the effect of the synthetic SL analogue rac-GR24 on resistance against necrotrophic pathogen Botrytis cinerea. In rac-GR24-treated plants, disease resistance against B. cinerea was enhanced in an ethylene- and camalexin-dependent manners. Expression of the ethylene-related genes and the camalexin biosynthetic gene and camalexin accumulation after pathogen infection were enhanced by immune priming in rac-GR24-treated plants. These suggest that SL-mediated immune priming is effective for many types of resistance mechanisms in plant self-defense systems.\u0000\u0000<img alt=\"\" src=\"https://www.jstage.jst.go.jp/pub/jpestics/advpub/0/advpub_D24-019/figure/advpub_D24-019.png\"/>\u0000Fullsize Image","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"107 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From 400 active isolates found during the primary screening, Cry1Ac and Cry2A, which are known to be active against H. zea, were removed using multiplex-primer PCR and high-throughput column chromatography. This process reduced the number of active cultures to 48. DNA segments encoding Domain III of these 48 cultures were amplified by PCR and sequenced. Sequencing revealed two novel Cry1B-type Domain IIIs. Further sequencing of the flanking regions of these domains revealed that one was part of Cry1Bj (GenBank: KT952325). However, the other Domain III lacked Domains I and II. Instead, this Domain III was associated with two open reading frames, ORF1 and ORF2. ORF1 was identified as an ATP-binding protein, and ORF2 as an ATPase, suggesting that Bt exchanges Domain III among homologous Cry proteins.\u0000\u0000<img alt=\"\" src=\"https://www.jstage.jst.go.jp/pub/jpestics/advpub/0/advpub_D24-011/figure/advpub_D24-011.png\"/>\u0000Fullsize Image","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"5 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141584872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
