Transcription factors (TFs) play a pivotal role in regulating gene expression, facilitating plant adaptation and response to various abiotic stresses. Among the 179 NAC TFs encoded in the soybean genome, several are differentially expressed under stress conditions; however, the functional role of GmNAC3 in drought tolerance remains largely unknown. In this study, we cloned the 840 bp coding sequence of GmNAC3 and developed transgenic soybean hairy roots via Agrobacterium-mediated transformation to explore its role in drought response. The physiological and molecular responses of GmNAC3 overexpression (OE) chimeric soybean plants were assessed under polyethylene glycol (PEG)-simulated drought stress using Hoagland nutrient solution. Compared to empty vector (EV) controls, OE plants exhibited enhanced drought tolerance, including improved phenotypic traits, better root development, and stress resilience. Notably, OE plants showed a 23.9% reduction in hydrogen peroxide accumulation and a 31.25% decrease in superoxide anion levels. Biomass analysis on MS medium revealed significantly higher fresh and dry weights of OE hairy roots across different mannitol concentrations compared to EV roots. Furthermore, GmNAC3 overexpression led to the upregulation of key downstream genes involved in stress response, particularly GmLAC5 and GmLAC7. These findings suggest that GmNAC3 enhances drought tolerance in soybean by regulating both physiological and molecular pathways. Overall, GmNAC3 represents a promising target for genetic engineering aimed at improving drought resistance in soybean and potentially other crops.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":"16 1","pages":"435-449"},"PeriodicalIF":0.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in 2021, China launched its first pilot program for the commercial cultivation of GM food crops and subsequently expanded their cultivation. Previously, the only GM plants cultivated in China were insect-resistant cotton and virus-resistant papaya. The regulatory and policy shifts, from initial research and cautious development to accelerated commercialization, led to significant changes in China's safety-related regulatory framework for genetically modified organism (GMOs). Here, China's progress in GMO research and commercialization over the past three decades is comprehensively analyzed. This review traces the evolution of core regulations governing GMO safety, summarizes the Chinese model of GMO safety governance, and highlights the remaining challenges as commercialization progresses. The goal was to present the international community with a GMO safety governance model reflecting China's characteristics and practices, offering a Chinese solution to balancing GMO commercial adoption with ecological preservation.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":"51 1","pages":"450-481"},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a key strategy in green pest control, the effectiveness of genetically modified (GM) insect-resistant crops largely depends on the extent of farmer acceptance. Based on survey data from 426 GM maize pilot farmers in Yunnan Province, this study employs an ordered Logit model to analyze the key factors influencing farmers' adoption intentions from a behavioral decision-making perspective. The results indicate that (1) cognition, value orientation, and social trust are the primary drivers of farmers' willingness to adopt GM maize; (2) the impact of risk perception is context-dependent, exerting a significant positive moderating effect on planting decisions among farmers with higher levels of social trust; (3) planting experience reinforces the effects of cognition and social trust and amplifies the role of value orientation.

Most studies in literature assume that environment-related technologies directly diminish environmental contamination, while this study suggests that environment-related technologies indirectly mitigate environmental hazards through interactions with agricultural land use, agricultural value addition, and transportation infrastructure. Thus, this study determines to disclose the influence of agricultural land use, agricultural value added, and transportation infrastructure investment on ecological damage in countries with the highest population density during the period 1990-2022; and the sole moderating effect of environment-related technologies in the association of the proposed regressors with CO2 emissions. Results illustrate that agricultural land use and investment in transportation infrastructure contribute significantly to CO2 emissions, but only in the long term. However, agriculture value addition strongly promotes environmental contamination in both the short and long term. Furthermore, in the long run, the reversed U-designed EKC premise holds only for the top five most populous countries. Environmental contamination can be mitigated through environmentally relevant technologies when interacting with agriculture land use, value addition of agricultural and investment in transportation infrastructure. Finally, (>-1.115) is the estimated threshold level of environment-related technologies, at which agricultural land use, agricultural value added, and transportation infrastructure can significantly improve environmental quality. Policymakers in densely populated countries should prioritize the adoption of environmentally friendly technologies in agriculture and transportation to achieve environmental sustainability.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":"47 1","pages":"340-359"},"PeriodicalIF":0.0,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drought stress seriously affects the growth and development process of plants and causes serious damage to maize yield. In the early stage, our research group conducted transcriptome sequencing analysis on the drought-resistant maize inbred line H8186 and screened out a gene with significantly down-regulated expression, Phylloplanin-like (ZmPL1). The ZmPL1 gee expression pattern was analyzed under various abiotic stresses, and the results showed that this gene was greatly affected by drought stress. Subcellular localization analysis showed that the protein was localized on the cell membrane. In order to verify the role of ZmPL1 in drought stress, we overexpressed ZmPL1 in yeast and found that the expression of ZmPL1 could significantly increase the drought sensitivity of yeast. Next, ZmPL1 transgenic plants were obtained by infecting maize callus using Agrobacterium-mediated method. Under drought stress, compared with overexpression lines, gene-edited lines had higher germination rate and seedling survival rate, lower accumulation of MDA, relative conductivity and ROS, higher antioxidant enzyme activity, and the expression levels of stress-related genes and ROS scavenging-related genes were significantly increased. Exogenous application of ABA to each lines under drought stress attenuated the damage caused by drought stress on ZmPL overexpressing plants. In summary, ZmPL1 negatively regulates drought tolerance in maize.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":"20 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding knowledge and perceptions of GMFs is essential, as these factors influence acceptance and attitudes. This study, the first of its kind in Lebanon, aimed to assess the knowledge, attitudes, and perceptions regarding GMFs and to explore their association with socio-demographic characteristics. A cross-sectional study was conducted with 1,001 participants who completed a 50-item questionnaire, followed by a 15-minute educational session on GMFs. Statistical analysis was performed using SPSS. Prior to the educational session, participants had an average knowledge score of 60.3 ± 17.4%, which significantly increased to 83.0 ± 15.8% afterward. Attitude and perception scores improved from an average of 30.3 ± 25.1% pre-intervention to 38.9 ± 12.4% post-intervention. Females demonstrated significantly higher knowledge scores, and educational attainment was positively correlated with knowledge levels both pre- and post-intervention. Younger participants and those in health-related fields scored higher before the intervention, while unemployed individuals scored lower. Additionally, higher educational levels and health-related educational backgrounds were linked to better attitudes and perceptions pre-intervention, while unemployment correlated with lower scores. Interestingly, multivariate regression analysis indicated that being under 35 years of age, having a health-related educational background, and holding a university degree were predictors of higher GMF knowledge. Consequently, individuals with initially lower knowledge level benefited the most from the educational intervention, exhibiting the greatest knowledge increases post-education. Our findings underscore the importance of targeted educational initiatives to bridge knowledge gaps and address misconceptions regarding GMFs.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":"24 1","pages":"144-155"},"PeriodicalIF":0.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
