In other species, mutations in <i>DMR6</i> genes have been demonstrated to have the effect of increasing salicylic acid levels with corresponding activation of systemic acquired resistance. In this research, gene editing was used to create deleterious mutant alleles of <i>DMR6</i> genes at two loci in the tobacco genome. In anticipation of potential adverse effects such as reduced plant productivity caused by mutations in members of this gene family, different genetic combinations of mutant alleles were established in five recipient genotypes, including those with genetic potential for increased leaf number. Relative to wild-type control lines, double homozygous <i>DMR6</i> mutants exhibited significantly improved and impressive resistance to black shank and bacterial wilt caused by economically important soilborne pathogens <i>Phytophthora nicotianae</i> and <i>Ralstonia solanacearum</i>, respectively. This mutant combination was associated with late-season physiological leaf spotting prior to harvesting, however, resulting in significantly reduced cured leaf yields. Improved resistance of single homozygous mutants was inconsistent across recipient genotypes. Double heterozygous mutant genotypes exhibited greater levels of soilborne pathogen resistance but did not exhibit the leaf spotting characteristic. Although slightly lower yielding than wild-type genotypes, this genetic combination may offer a satisfactory tradeoff for tobacco breeders when considering both improved pathogen resistance and yielding ability. Strategic temporal or spatial modification of <i>DMR6</i> expression might be pursued to achieve maximal pathogen resistance with minimal corresponding adverse effects in this species.</p>","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous analyses of historical data (1948–1998) examined trends in seed protein and oil concentrations over time across different maturity groups (MGs) in the United States. Our study extends the previous analysis through the more recent period of 1999–2022. We found that seed protein concentration significantly declined over time in short (MG0, MG1, and MG2) and mid (MG3, MG4, and MG5) MGs at a rate of 0.04% and 0.06% per year, respectively. In contrast, protein levels in long MGs (MG6, MG7, and MG8) increased at a rate of 0.10% per year. For seed oil concentration, however, no distinct differences among MG classes were observed; instead, oil concentration showed a consistent increase of 0.11% per year across all classes. Additionally, we identified an inverse relationship between protein and oil concentrations, with protein decreasing by 0.26% for every 1% increase in oil, regardless of MG category. These insights helped to identify predictors for modeling seed protein and oil concentrations, allowing the assessment for additional information to increase prediction accuracy. We found that a simpler model including latitude, longitude, sowing date, and mean temperature from sowing to flowering performed similarly to more complex models that included additional environmental variables. Moreover, nonlinear relationships between predictors appear to play a significant role, as models capable of capturing these interactions outperformed linear approaches.</p>","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144869616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While epigenetic mechanisms offer potential for resistance, critical gaps hinder their practical application. This review explores the role of epigenetic mechanisms in enhancing aflatoxin resistance in peanuts. This study involved an analysis of the literature on the role of epigenetic modifications in regulating peanut defense-related genes against <i>Aspergillus flavus</i>. This included reviewing progress in epigenome-wide association studies and CRISPR–dCas9-mediated editing technologies, which allow the modification of resistance genes without changing the plant core genetic structure. Significant developments have been made in employing epigenetic mechanisms to improve resilience in other crops. These approaches have the potential to improve resistance to aflatoxin-producing fungi. However, few field studies have validated the long-term effectiveness of epigenetic modifications. Research must focus on establishing stable resistance traits across diverse environments. The absence of standardized protocols for peanut-specific modifications complicates progress. The heritability and environmental stability of epigenetic marks in peanuts remain unclear. Current studies have focused primarily on a limited range of peanut genotypes, emphasizing the need for research across diverse genetic backgrounds to ensure broader applicability. Furthermore, a unified model linking epigenetic mechanisms with aflatoxin resistance is needed to bridge molecular findings with practical breeding applications. Consequently, addressing these gaps through interdisciplinary approaches and research will enable the development of resilient and aflatoxin-resistant peanut varieties. Thus, overcoming these challenges will contribute significantly to global food security, sustainable agriculture, and the long-term stability of peanut production in diverse environments.</p>","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144869560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
