Fullerol C(OH) nanoparticles (FNP)-wheat- interaction outcome is more complicated in the presence of drought. This study sheds light on how the presence of FNP affects food and feed safety from the perspective of mycotoxin contamination. The study aims to determine the influence of FNP at environmentally plausible concentrations on wheat growth under drought stress and on the aggressiveness of during wheat germination, as well as the influence of FNP on the secondary metabolite profile during the inappropriate wheat storage. The co-occurrence of drought and FNP inhibited germination and shoot growth, while an application of FNP alone had no negative effect on plant growth. Wheat pre-treated with FNP showed a concentration dependent resistance pattern to aggressiveness. Nevertheless, using a LC-MS/MS based multi-mycotoxin method, six secondary fungal metabolites: 3-nitropropionic acid (<LOD -775.7336 ± 10.7752 ng mL), aflatoxin B1 (<LOD -6.78 ± 0.43 ng mL) and B2 (<LOD -0.07 ± 0.00 ng mL), aflatoxicol (<LOD -0.37 ± 0.16 ng mL), kojic acid (<LOD -1337.87 ± 189.04 ng mL), and O-methylsterigmatocystin (<LOD -0.17 ± 0.00 ng mL), were detected. FNP affected secondary metabolism of during inappropriate wheat storage and increased the concentration of secondary metabolites in a concentration-dependent pattern (3-nitropropionic acid and kojic acid). In addition, aflatoxicol production was provoked in FNP treated samples.
在干旱条件下,富勒醇C(OH)纳米颗粒(FNP)与小麦的相互作用结果更为复杂。本研究从霉菌毒素污染的角度揭示了FNP的存在如何影响食品和饲料安全。该研究旨在确定在环境相关浓度下FNP对干旱胁迫下小麦生长以及小麦萌发过程中病原菌侵袭力的影响,以及FNP对小麦储存不当期间次生代谢产物谱的影响。干旱和FNP共同存在会抑制发芽和地上部生长,而单独施用FNP对植物生长没有负面影响。用FNP预处理的小麦对病原菌侵袭力表现出浓度依赖性抗性模式。然而,使用基于液相色谱-串联质谱的多霉菌毒素方法,检测到了六种次生真菌代谢产物:3-硝基丙酸(<检测限 -775.7336 ± 10.7752 ng/mL)、黄曲霉毒素B1(<检测限 -6.78 ± 0.43 ng/mL)和B2(<检测限 -0.07 ± 0.00 ng/mL)、黄曲霉毒醇(<检测限 -0.37 ± 0.16 ng/mL)、曲酸(<检测限 -1337.87 ± 189.04 ng/mL)和O-甲基柄曲霉素(<检测限 -0.17 ± 0.00 ng/mL)。FNP在小麦储存不当时影响了病原菌的次生代谢,并以浓度依赖性模式增加了次生代谢产物的浓度(3-硝基丙酸和曲酸)。此外,在FNP处理的样品中引发了黄曲霉毒醇的产生。
