Silicon Mitigates Aluminum Toxicity of Tartary Buckwheat by Regulating Antioxidant Systems

引用

Phyton-International Journal of Experimental Botany 2024年第1期93卷 1-13页

作者： Anyin Qi Xiaonan Yan Yuqing Liu Qingchen Zeng Hang Yuan Huange Huang Chenggang Liang Dabing Xiang Liang Zou Lianxin Peng Gang Zhao Jingwei Huang Yan Wan Key Laboratory of Coarse Cereal Processing Ministry of Agriculture and Rural AffairsSichuan Engineering&Technology Research Center of Coarse Cereal IndustrializationCollege of Food and Biological EngineeringChengdu UniversityChengdu610106China research center of Buckwheat Industry Technology School of Life SciencesGuizhou Normal UniversityGuiyang550001China

Aluminum (Al) toxicity is a considerable factor limiting crop yield and biomass in acidic soil. Tartary buckwheatgrowing in acidic soil may suffer from Al poisoning. Here, we investigated the influence of Al stress on the growthof tartary buckwheat seedling roots, and the alleviation of Al stress by silicon (Si), as has been demonstrated inmany crops. Under Al stress, root growth (total root length, primary root length, root tips, root surface area, androot volume) was significantly inhibited, and Al and malondialdehyde (MDA) accumulated in the root tips. At thesame time, catalase (CAT) and ascorbate peroxidase activities, polyphenols, flavonoids, and 1,1-diphenyl-2-picrylhydrazyl(DPPH) and 2,2′-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) free-radical scavenging abilitywere significantly decreased. After the application of Si, root growth, Al accumulation, and oxidative damage wereimproved. Compared to Al-treated seedlings, the contents of ·O2− and MDA decreased by 29.39% and 25.22%,respectively. This was associated with Si-induced increases in peroxidase and CAT enzyme activity, flavonoidcompounds, and free-radical scavenging (DPPH and ABTS). The application of Si therefore has positive effectson Al toxicity in tartary buckwheat roots by reducing Al accumulation in the roots and maintaining oxidationhomeostasis.
