To combat this disease, chitosan nanoparticles (CNPs) were combined with the fungicide cyproconazole (CYP) and applied as a foliar spray 24 h postinoculation (hpi) with fungal urediniospores. Plant samples were analyzed to assess fungal progression by examining pustule formation and quantifying fungal DNA content in leaf tissues. Treatment with CNPs and the cyproconazole-chitosan nanocomposite (C-CYP) resulted in significantly smaller pustules or their absence and reduced fungal DNA levels compared to controls. Additionally, enzyme assays revealed that the activities of peroxidase, catalase, polyphenol oxidase, and phenylalanine ammonia-lyase significantly increased 24 h post-treatment with CNPs compared to controls. Furthermore, transcription levels of WAK-2, NPR-1, and Chitinase genes were notably upregulated in plants treated with CNPs and C-CYP at 24 h post-treatment. These findings suggest that the combination of chitosan nanoparticles and cyproconazole not only effectively controls wheat stem rust but also reduces environmental hazards by requiring lower chemical dosages.","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 7","pages":"1413–1424"},"PeriodicalIF":2.9,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144807923","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}

Traditionally, variety identification relies on physicochemical property measurements, which are time-consuming and require laboratory analysis. Instead, we used the ATR–FTIR spectra from 731 apricots divided into calibration (512) and test (219) sets and three machine learning models (i.e., partial least-squares-discriminant analysis (PLS-DA), support vector machine (SVM), and random forest (RF)) to accurately predict 97% of the test samples. Additionally, careful inspection of the PLS-DA regression vectors revealed a strong correlation between the spectra and biochemical composition in sugar and organic acids, validating ATR–FTIR spectroscopy as a viable alternative for variety identification. Finally, to validate the results, additional models were constructed using the physicochemical data from the apricots. These reference models were then tested using the same data splits as the spectroscopic data used as a reference method, obtaining similar results with both approaches.","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 7","pages":"1373–1381"},"PeriodicalIF":2.9,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12309246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144755345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the exogenous application of the elicitors salicylic acid (SA), methyl jasmonate (MeJA), pimelic acid (PA), suberic acid (SuA), and azelaic acid (AzA) was evaluated for its effect on the accumulation of bioactive metabolites in in vitro-cultivated plants. Exposure to these compounds significantly modulated the expression of key genes in the phenylpropanoid and flavonoid pathways, including pal, chs, chi, and fnsII, as well as regulatory genes such as myb12, bhlh, and wrky33, enhancing PAL activity and the accumulation of C-glycosyl flavones including schaftoside, neoschaftoside, saponarin, and swertiajaponin. This priming process improved the antifungal activity of the extracts, with SuA at 75 μM and MeJA at 50 μM were identified as the most effective treatments. The in vitro culture approach enabled the assessment of protected and hard-to-access species without the need for wild harvesting. These results suggest that the exogenous application of elicitors constitutes an efficient strategy to modulate the biosynthesis of specialized metabolites, with implications for the development of biocontrol agents and the improvement of efficiency in sustainable agricultural systems.","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 7","pages":"1497–1509"},"PeriodicalIF":2.9,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144807597","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, aligning with circular economy principles, there is growing interest in utilizing bioconverter insects like the black soldier fly (Hermetia illucens). We explored the potential of H. illucens pupal grown on discarded agro-industrial waste to obtain enriched chitosan sources for plant biostimulants and protectors. Chitin was extracted from the pupal exuviae, and the properties of bleached (ChB) and nonbleached (ChU) chitosan fractions were compared. Both fractions exhibited structural similarities to commercial chitosan, with ChU showing a superior antioxidant capacity. In hydroponic lettuce cultivation, ChU significantly increased the biomass and chlorophyll content, while ChB had no notable effect. Both ChU and ChB activated auxin signaling in a transgenic tomato model and exhibited fungicidal activity against Fusarium solani f. sp. eumartii. These findings indicate that H. illucens pupal exuviae, cultivated on discarded agro-industrial waste, offer a valuable alternative for use as a plant biostimulant. This type of research forms the foundational basis for recognizing the potential of waste as a resource to innovate and create various products aligned with the circular economy strategy.","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 8","pages":"1619–1631"},"PeriodicalIF":2.9,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860205","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}

The n-P treatments increased plant fresh weight by 21.2–30.2% relative to i-P, demonstrating superior growth promotion. Physiological analysis revealed that n-P enhanced stress adaptation through the modulation of antioxidant enzyme activities, indicating improved oxidative stress management. Importantly, n-P application boosted reproductive success with 62.0% higher pod fresh weight and 21.5% increased total protein content compared to i-P. Postharvest soil analysis showed additional benefits of n-P fertilization, including 69% lower residual Olsen-P and ameliorated soil acidification compared with the i-P group.

In this regard, the production of various crops with therapeutic and nutritional values has been of interest in different societies. Industrialization of agriculture, limitation of natural resources, and population growth highlighted the importance of producing valuable species of medicinal plants. Cannabis is considered a medicinal plant, whose proliferation and mass production have attracted a lot of attention in recent years. The demand for the use of cannabis in the pharmaceutical and food industries is increasing significantly. Various methods of propagation and mass production have accordingly become the most important medicinal aspects of cannabis production. Despite the current achievements in improving cannabis production through the introduction of new varieties and different propagation methods, the development of large-scale micropropagation and modern breeding strategies, as well as the genetic conservation of this plant, should be given more attention. However, the application of plant biotechnologies requires high-throughput in vitro culture systems that enable the transformation and development of new cannabis varieties on a large scale. The present review summarizes the advantages and disadvantages of common methods of sexual and asexual propagation of cannabis seedlings.","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 7","pages":"1191–1214"},"PeriodicalIF":2.9,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144809019","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}

Advances in nanosensors capable of measuring H2O2 within the living plant in real time have informed a quantitative theory to describe the spatiotemporal profile of its concentration─labeled a signaling waveform. A heretofore unaddressed aspect of the theory is the role of the existing basal H2O2 concentration level within the plant before and after stress wave propagation, potentially informing mechanisms of stress priming─or state changes associated with prior, low magnitude levels of stress that condition the resulting waveform. Herein, we develop a mathematical description of wave propagation within an existing basal level of H2O2. We show that the shape and intensity of the waveform can be mathematically decoupled from the basal H2O2 concentration. This opens the possibility that the equilibrium basal concentration can operate as a distinct, orthogonal signaling channel, separate from the acute waveform following a discrete stress event. The mathematics developed herein may find utility in a more detailed description of mechanisms such as stress priming. More broadly, the results will aid in extending waveform analysis across diverse plant species and environmental conditions.","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 7","pages":"1434–1441"},"PeriodicalIF":2.9,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144809009","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}
