However, the crossover points of JA and GA signals and the pathways through which they interact to regulate anthocyanin biosynthesis are poorly understood. Here, we investigated the molecular mechanism by which the zinc finger protein (ZFP) transcription factor <i>Malus domestica</i> ZFP7 (MdZFP7) regulates anthocyanin biosynthesis by integrating JA and GA signals at the transcriptional and post-translational levels. MdZFP7 is a positive regulator of anthocyanin biosynthesis, which fulfills its role by directly activating the expression of <i>MdMYB1</i> and enhancing the transcriptional activation of MdWRKY6 on the target genes <i>MdDFR</i> and <i>MdUF3GT</i>. MdZFP7 integrates JA and GA signals by interacting with the JA repressor apple JASMONATE ZIM-DOMAIN2 (MdJAZ2) and the GA repressor apple REPRESSOR-of-ga1-3-like 3a (MdRGL3a). MdJAZ2 weakens the transcriptional activation of <i>MdMYB1</i> by MdZFP7 and disrupts the MdZFP7–MdWRKY6 interaction, thereby reducing the anthocyanin biosynthesis promoted by MdZFP7. MdRGL3a contributes to the stimulation of anthocyanin biosynthesis by MdZFP7 by sequestering MdJAZ2 from the MdJAZ2–MdZFP7 complex. The E3 ubiquitin ligase apple BOI-related E3 ubiquitin-protein ligase 3 (MdBRG3), which is antagonistically regulated by JA and GA, targets the ubiquitination degradation of MdZFP7. The MdBRG3-MdZFP7 module moves the crosstalk of JA and GA signals from the realm of transcriptional regulation and into the protein post-translational modification. In conclusion, this study not only elucidates the node-role of MdZFP7 in the integration of JA and GA signals, but also describes the transcriptional and post-translational regulatory network of anthocyanin biosynthesis with MdZFP7 as the hub.</p></div>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":"67 5","pages":"1339-1363"},"PeriodicalIF":9.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these methods, spray-induced gene silencing (SIGS) emerges as particularly promising due to its convenience and feasibility for development. This approach is a new technology for plant disease management, in which double-stranded RNAs (dsRNAs) targeting essential or virulence genes are applied to plants or plant products and subsequently absorbed by plant pathogens, triggering a gene silencing effect and the inhibition of the infection process. Spray-induced gene silencing has demonstrated efficacy in laboratory settings against various fungal pathogens. However, as research progressed from the laboratory to the greenhouse and field environments, novel challenges arose, such as ensuring the stability of dsRNAs and their effective delivery to fungal targets. Here, we provide a practical guide to SIGS for the control of plant pathogenic fungi. This guide outlines the essential steps and considerations needed for designing and assessing dsRNA molecules. It also addresses key challenges inherent to SIGS, including delivery and stability of dsRNA molecules, and how nanoencapsulation of dsRNAs can aid in overcoming these obstacles. Additionally, the guide underscores existing knowledge gaps that warrant further research and aims to provide assistance to researchers, especially those new to the field, encouraging the advancement of SIGS for the control of a broad range of fungal pathogens.</p></div>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":"67 3","pages":"801-825"},"PeriodicalIF":9.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143254275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
