{"title":"Transcription factor BbCDR1 regulates the orchestration between conidial formation and maturation in the entomopathogenic fungus Beauveria bassiana","authors":"Hui Zhang, Ajing Mao, Yu Liu, Yu Fu, Jiahao Cheng, Dan Jin, Yanhua Fan","doi":"10.1002/ps.8662","DOIUrl":"https://doi.org/10.1002/ps.8662","url":null,"abstract":"BACKGROUNDThe entomopathogenic fungus <jats:italic>Beauveria bassiana</jats:italic> has been widely used for pest biocontrol with conidia serving as the main active agents. Conidial yield and quality are two important characteristics in fungal conidia development, however, the regulatory mechanisms that orchestrate conidial formation and development are not well understood.RESULTSIn this study, we identified a Zn<jats:sub>2</jats:sub>Cys<jats:sub>6</jats:sub> transcription factor BbCDR1 that inhibits conidial production while promoting conidial maturation. Compared with the wild type, the <jats:italic>ΔBbCDR1</jats:italic> mutant exhibited a 1.88‐fold increase in conidial yield but a reduction in conidial quality, including decreased cell wall integrity and trehalose synthesis. The deletion of <jats:italic>BbCDR1</jats:italic> also led to reduced conidial germination rates under oxidative, osmotic, conidial wall disruption and UV stresses. Interestingly, <jats:italic>ΔBbCDR1</jats:italic> exhibited an increase of fungal virulence with a 12.5% decrease in LT<jats:sub>50</jats:sub> compared to the wild type.CONCLUSIONSFurther analysis revealed that BbCDR1 represses the expression of <jats:italic>BbbrlA</jats:italic> and activates <jats:italic>BbwetA</jats:italic>, two components of the central developmental pathway (CDP) that regulate conidial initiation and maturation, respectively. These findings suggest that BbCDR1 plays a crucial role in conidial development and a new target gene for the genetic engineering of highly active fungal insecticides. © 2025 Society of Chemical Industry.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"49 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, using DNA‐based metabolic resistance markers, we assessed the efficacy of the dual active ingredients net Royal Guard against pyrethroids‐resistant malaria vectors in Cameroon, establishing its long‐term impact on mosquitoes' life traits after exposure.RESULTSCone assays revealed low efficacy of Royal Guard against field <jats:italic>Anopheles</jats:italic> populations. However, analysis of the survival curves revealed that unexposed mosquitoes lived longer (11.4 ± 0.4 days) than those exposed to Royal Guard (7.9 ± 0.2 days) (<jats:italic>χ</jats:italic><jats:sup>2</jats:sup> = 6; <jats:italic>P</jats:italic> = 0.05), indicating that despite the lower immediate mortality observed against resistant mosquitoes, there is a long‐term effect on <jats:italic>Anopheles funestus</jats:italic> longevity. High blood‐feeding inhibition rate was observed (44–80% <jats:italic>versus</jats:italic> 11–41%), indicating that this net has a negative impact on blood meal intake. Additionally, female mosquitoes exposed to this net exhibited a 25% reduction in oviposition, 18.30% reduction in fecundity, 8.10% reduction in offspring, and a 74.74% infertility rate compared to the control. Genotyping of key resistance markers revealed that, metabolic markers and L1014F<jats:italic>‐Kdrw</jats:italic> are associated with the reduced efficacy observed, with homozygote‐resistant mosquitoes significantly more able to survive and live longer after exposure than homozygote‐susceptible mosquitoes (odds ratio = 15.79; confidence interval = 5.35–43.27; <jats:italic>P</jats:italic> &lt; 0.0001).ConclusionThis study revealed that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood‐feeding ability and interestingly reduces their fecundity/fertility. © 2025 The Author(s). <jats:italic>Pest Management Science</jats:italic> published by John Wiley &amp; Sons Ltd on behalf of Society of Chemical Industry.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"45 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
