While crops need sulphur in slightly lower amounts than phosphorus, maintaining optimum sulphur levels is crucial for oilseed yield and quality. Factors such as sulphur dynamics, impact of deficiency, application methods, and climate change must be addressed to improve agricultural practices. In South Asian countries like India, Pakistan, and Bangladesh, oilseeds are vital to the agricultural economy, supporting food security, livelihoods, and economic growth. However, climate change, marginal land cultivation, and a shift to more profitable crops like wheat and maize have led to a decline in oilseed productivity. Sulphur is particularly important for vital plant functions, including protein synthesis, chlorophyll formation, and resistance to abiotic stress. Proper management of sulphur can significantly enhance the yield, oil content, and seed quality. Sulphur fertilization improves crop resilience to pests, diseases, and environmental stresses, resulting in healthier plants. To optimize oilseed production, best practices for sulphur management like integrated nutrient management, regular soil testing, and the strategic application of sulphur-enriched fertilizers must be adopted. Despite its significance, many South Asian soils suffer from sulphur deficiency due to inadequate replenishment and reliance on high-analysis fertilizers. By enhancing sulphur availability, oilseed producers can significantly increase crop yields, improve oil content, and promote overall plant health, contributing to the agricultural economy and food security in the region. This manuscript aims to evaluate the critical role of sulphur in enhancing the yield, oil quality, and stress resilience of oilseed crops in South Asia.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 2","pages":"Pages 118-130"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221654","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}

Adopting the \"One Health\" concept, we mainly present the prevalence of vancomycin-resistant bacteria over the past decade from 40 human, animal, environmental, and food sources across various regions, both domestically and internationally. The statistical results indicate that vancomycin-resistant bacteria are primarily concentrated in hospitals and their surrounding environments. The prevalence of resistant bacteria in hospital wastewater in South Africa reaches as high as 96.77%, followed by Pakistan and China's Taiwan region, where the resistance rates are 56.5% and 29.02%, respectively. The vancomycin average resistance rate in domestic human-source bacteria (1.41%) is overall higher than that in international human-source bacteria (0.47%). The prevalence of resistant bacteria in pediatric patients across various regions is relatively low (<1%). It is worth noting that although the use of vancomycin is prohibited in livestock farming, vancomycin- resistant bacteria can still be detected in livestock, related products and environment, posing a potential threat to human health. Based on the statistical analysis results, we summarize several common vancomycin resistance mechanisms and the transmission mechanisms, and clarify the differences in the prevalence of resistant bacteria across the \"human-animal-food-environment\" interface for further analyzing the distribution and transmission risks of vancomycin-resistant bacteria in different hosts worldwide.

Representative transgenic maize (Shuang Kang 12-5, DBN9936, MON810) and soybean (DBN9004, GTS40-3-2, SHZD32-1) were selected as test objects.

In order to quickly obtain DNA, seed samples use nucleic acid release agents to obtain templates that can be used for RPA amplification. In order to eliminate the interference of chlorophyll in leaves on RPA fluorescence signal and quickly obtain DNA, leaf samples use the nucleic acid rapid integrated extraction device developed by our laboratory to quickly obtain DNA and eliminate the chlorophyll interference. Combined with a portable metal bath for initiating RPA amplification, a blue light gel cutter for visual detection, and a rapid on-site detection method for transgenic maize and soybean was constructed. The entire detection process required approximately 20 minutes, and the detection result was consistent with the result of conventional PCR.
