These abandoned industrial spaces not only lead to persistent pollution problems, but also exacerbate the urban heat island effect, leading to a worsening microclimate. To address these issues, the concept of green infrastructure (GI) has emerged as a sustainable ecological restoration strategy, and it is an important tool for urban renewal and industrial land transformation. In this study, the landscape environment of the industrial site of Henrichshutte in Germany and the surrounding industrial plant was taken as an example, and ecological restoration and plant landscape design were carried out using the GI concept. Two climate simulation tools, ENVI-met and WindPerfect DX, were comprehensively adopted to simulate the environment of the site in detail. Based on an analysis of the potential temperature, PMV, wind speed, and UTCI data of the site, it was demonstrated that the plant landscape improved the microclimate of the industrial plant. The results show that the reasonable allocation of plants can effectively reduce surface temperature and building temperature, increase air humidity, alleviate the local heat island effect, and enhance the thermal comfort of the human body. The simulation results highlight the practical application value of the GI concept in improving the ecological benefit, social function, and landscape aesthetics of industrial land. This study provides a new idea for the ecological restoration and environmental optimization of urban industrial land through the combination of green infrastructure and plant landscape design, and emphasizes the important role of green infrastructure in alleviating the urban heat island effect and promoting the sustainable development of urban landscape spaces.</p>","PeriodicalId":56267,"journal":{"name":"Plants-Basel","volume":"14 5","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11902038/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the physicochemical properties, free sugar and organic acid content, and bioactive compounds in four kiwifruit cultivars: Hayward (HW), Halla Gold (HG), Jecy Gold (JG), and Sweet Gold (SG). This study aimed to determine variations in the composition of these cultivars and assess their antioxidant potential. The pH did not significantly differ among the kiwifruit cultivars. Sweetness and acidity are key sensory attributes in fruit, and SG exhibited the highest acidity, soluble solid content, and reducing sugar content. Accordingly, SG had the highest free sugar (11.25 g/100 mL) and organic acid (13.08 g/100 mL) levels. Phenolic acid (473.01 μg/mL) and flavonol (96.43 μg/mL) contents were most abundant in SG. In this cultivar, chlorogenic acid and epigallocatechin levels were the highest, while epicatechin and naringenin were detected only in SG. Finally, antioxidant activities (i.e., DPPH, ABTS, and hydroxyl radical scavenging activities and FRAP) were highest in SG, followed by HG, JG, and HW. The SG cultivar used in this study exhibits strong antioxidant activity, disease-suppressing effects, skin protection properties, and the potential to reduce the risk of chronic diseases due to its high phenolic compound content. These findings suggest that SG, which possesses excellent taste and functional properties, may serve as a promising candidate for the development of high-quality kiwifruit-based products.</p>","PeriodicalId":56267,"journal":{"name":"Plants-Basel","volume":"14 5","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11901894/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the documented role of nanosilica (n-SiO₂) in enhancing crop resilience, its full growth-cycle effects on soybeans under drought stress remain elusive. This study aimed to evaluate the efficacy of n-SiO₂ at a concentration of 100 mg kg^-1 in a soil medium for enhancing drought tolerance in soybeans through a full life-cycle assessment in a greenhouse setup. To elucidate the mechanisms of n-SiO₂ action, key physiological, biochemical, and yield parameters were systematically measured. The results demonstrated that n-SiO₂ significantly increased silicon content in shoots and roots, restored osmotic balance by reducing the Na⁺/K⁺ ratio by 40%, and alleviated proline accumulation by 35% compared to the control, thereby mitigating osmotic stress. Enzyme activities related to nitrogen metabolism, including nitrate reductase (NR) and glutamine synthetase (GS), improved by 25-30% under n-SiO₂ treatment compared to the control. Additionally, antioxidant activity, including superoxide dismutase (SOD) levels, increased by 15%, while oxidative stress markers such as hydrogen peroxide (H₂O₂) and malondialdehyde (MDA) decreased by 20-25% compared to the control. Furthermore, yield components were significantly enhanced, with pod number and grain weight increasing by 15% and 20%, respectively, under n-SiO₂ treatment compared to untreated plants in drought conditions. These findings suggest that n-SiO₂ effectively enhances drought resilience in soybeans by reinforcing physiological and metabolic processes critical for growth and yield. This study underscores the potential of n-SiO₂ as a sustainable amendment to support soybean productivity in drought-prone environments, contributing to more resilient agricultural systems amidst increasing climate variability. Future research should focus on conducting large-scale field trials to evaluate the effectiveness and cost-efficiency of n-SiO₂ applications under diverse environmental conditions to assess its practical viability in sustainable agriculture.</p>","PeriodicalId":56267,"journal":{"name":"Plants-Basel","volume":"14 5","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11902048/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their roles in non-seed storage organs such as underground tubers are largely unknown. This study presents the first genome-scale analysis of the <i>LEA_5</i> family in tigernut (<i>Cyperus esculentus</i> L.), a Cyperaceae plant producing desiccation-tolerant tubers. Four <i>LEA_5</i> genes identified from the tigernut genome are twice of two present in model plants <i>Arabidopsis thaliana</i> and <i>Oryza sativa</i>. A comparison of 86 members from 34 representative plant species revealed the monogenic origin and lineage-specific family evolution in Poales, which includes the Cyperaceae family. <i>CeLEA5</i> genes belong to four out of five orthogroups identified in this study, i.e., LEA5a, LEA5b, LEA5c, and LEA5d. Whereas LEA5e is specific to eudicots, LEA5b and LEA5d appear to be Poales-specific and LEA5c is confined to families Cyperaceae and Juncaceae. Though no syntenic relationship was observed between <i>CeLEA5</i> genes, comparative genomics analyses indicated that LEA5b and LEA5c are more likely to arise from LEA5a via whole-genome duplication. Additionally, local duplication, especially tandem duplication, also played a role in the family expansion in <i>Juncus effuses</i>, <i>Joinvillea ascendens</i>, and most Poaceae plants examined in this study. Structural variation (e.g., fragment insertion) and expression divergence of <i>LEA_5</i> genes were also observed. Whereas <i>LEA_5</i> genes in <i>A. thaliana</i>, <i>O. sativa</i>, and <i>Zea mays</i> were shown to be preferentially expressed in seeds/embryos, <i>CeLEA5</i> genes have evolved to be predominantly expressed in tubers, exhibiting seed desiccation-like accumulation during tuber maturation. Moreover, <i>CeLEA5</i> orthologs in <i>C. rotundus</i> showed weak expression in various stages of tuber development, which may explain the difference in tuber desiccation tolerance between these two close species. These findings highlight the lineage-specific evolution of the <i>LEA_5</i> family, which facilitates further functional analysis and genetic improvement in tigernut and other species.</p>","PeriodicalId":56267,"journal":{"name":"Plants-Basel","volume":"14 5","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11902115/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The processing generates a large amount of waste and causes environmental issues. In order to reduce the environmental impacts, several approaches for the waste management of citrus fruits were proposed. The citrus fruit waste contains several functional compounds, but the extraction of these functional compounds requires adequate production facilities. The waste is not suitable to carry for long distances due to the high percent of water content and its heavy weight, and it is not suitable to store for a long time due to the occurrence of fermentation. Some of the approaches target the use of waste in the proximity of the processing factories. The application of citrus fruit waste for crop production in the agricultural fields close to the faculties is one of the possible management options. The evidence of citrus fruit waste as herbicidal, nematocidal, insecticidal, and anti-fungal materials has been accumulated in the literature over three decades. Several compounds involved in these functions have also been identified in the citrus fruits.
