However, the specific metabolic constituents driving their nutritional divergence remain poorly understood. Here, we applied widely targeted metabolomics to profile the curds of white (‘C’), green (‘G’), purple (‘P’), and yellow (‘Y’) cauliflowers. Pigment analysis demonstrated that ‘G’ accumulated the highest levels of chlorophyll a (46.76 mg/kg) and b (33.11 mg/kg), alongside active chlorophyll intermediates and moderate carotenoids (7.14 mg/kg). ‘Y’ accumulated the highest levels of carotenoids (11.17 mg/kg), which became visually dominant following partial chlorophyll degradation. The distinct coloration of ‘P’ was attributed to anthocyanins (0.63 mg/g), primarily delphinidin 3-glucoside, whereas ‘C’ retained minimal pigments. Compared to ‘C’, 1922, 1544, and 1607 differentially accumulated metabolites were identified in ‘G’, ‘P’, and ‘Y’, respectively. KEGG pathway and chemical classification analyses demonstrated that these DAMs were predominantly enriched in primary carbohydrate metabolism, amino acid biosynthesis, and secondary metabolic pathways. Our analysis revealed that colored cultivars broadly accumulated higher levels of soluble sugars, inulin, and essential amino acids, with a distinct elevation of <span>l</span>-lysine in ‘G’. Secondary metabolism exhibited strict cultivar specificity, as anthocyanins and specific hepatoprotective phenolics were found exclusively in ‘P’. Moreover, the anticancer precursor glucoraphanin peaked in ‘G’, while anti-inflammatory sinigrin and goitrogenic progoitrin were enriched in ‘P’ and ‘Y’. Overall, this comprehensive metabolic profiling serves as a valuable resource for cauliflower germplasm evaluation and guides target selection in quality-improved breeding.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"368 ","pages":"Article 115207"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149088018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

True nutritional status was defined from yield response to fertilization, and CND performance was assessed using diagnostic accuracy metrics and Net Yield Productivity (NYP).

Various nanocarbon-based materials may differently affect plant growth. Since their comparative influences on plant particularly at various conditions have not been studied; therefore, we aimed to study the effects of different carbon nanomaterials (graphene, graphene oxide, reduced graphene oxide, multi-walled carbon nanotubes, and OH-modified multi-walled carbon nanotubes) at concentrations of 0, 50, and 100 mg L^-1 on basil grown at 100, 75, and 50%wt of field capacity (FC) drought levels with three replications. The results demonstrated that the effects of different carbon-based nanomaterials on the physiological traits of basil under drought stress were significantly dependent on both the type of nanomaterial and the applied concentration. While electrolyte leakage (EL) significantly decreased by 27.5% to 46.4% with applying 50 mg L⁻¹ of all nanomaterials under 0.5FC conditions, except for multi-walled carbon nanotubes that exhibited toxic effects and led to a 92.9% increase in EL. This response was likely attributable to the complex interactions among the nanomaterial, foliar surface adsorption, variations in nanoparticle aggregation tendencies, and plant water status. Furthermore, applying 50 mg L⁻¹ of carbon nanomaterials significantly enhanced the maximum fluorescence by 10.5% to 29.4%. Nevertheless, these nanomaterials enhanced plant growth under severe drought stress (0.5FC) conditions. Furthermore, at this highest level of drought stress, lower concentrations of carbon nanomaterials (50 mg L^-1) improved several physiological parameters of the plant. An exception was observed with carbon nanotubes, which demonstrated superior performance at the highest concentration (100 mg L^-1). The findings revealed that carbon nanomaterials can enhance drought tolerance and physiological resilience in basil, especially at lower concentrations.
