Research ArticleOpen accessIn the author namesAccumulation and Effect of Manganese on Chloroplasts and Antioxidant Responses in Arabidopsis ThalianaJun Xing, Xue Yang, Cailing YuanIn this study, 5-day-old seedlings of Arabidopsis thaliana were exposed to 0, 0.5, and 1.0 mmol/L MnCl₂ for 6 days by using three independent biological replicates. The results indicated that Mn content in roots exhibited a dose-dependent increase with rising external Mn supply. The elevated Mn levels led to significant reductions in the nutrient content of K, Ca, Na, and … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 18 Jul 2026 · 824 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Ultra-High-Pressure Treatment on the Chemical Composition and Aroma of Flue-Cured Tobacco Leaves for Heated Tobacco ProductsXinbo Lu, Jie Yin, Ying Yuan et al.The influences of different Ultra-High-Pressure (UHP) treatments on the chemical composition and the low-temperature pyrolysis products of Flue Cured Tobacco Leaves (FCTL) that applied in heated tobacco products were investigated in this study. Results indicated that UHP treatment reduced total alkaloids content significantly (p<0.05), especially 500-600 MPa treatment group (2.34±0.00%, 2.34±0.01%). Increase in sugars and potassium content were observed after … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 19 Oct 2025 · 2,150 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Lead on the Chlorophyll and Antioxidant Response in the Leaves of Arabidopsis thalianaJun Xing, Cailing Yuan, Hui Yu et al.Lead (Pb) is a non-essential heavy metal element for plants. In this study, the effect of 0.025, 0.05, 0.1, 0.25, and 0.5 g/L Pb on the chlorophyll and antioxidant response was analyzed in the leaves of Arabidopsis thaliana. The results indicate that 0.025 g/L Pb had no significant effect on the fluorescence intensity of chlorophyll. However, 0.05, 0.1, 0.25, and … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 31 Mar 2024 · 4,628 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Mercuric Ion on the Oxidant Response and Calcium Ion in the Protoplasts of Arabidopsis ThalianaJun Xing, Rui Wu, Hui Yu et al.As a non-essential element for plant growth and development, the heavy metal mercury (Hg) has significant toxicity to plants. The aim of this study was to investigate the effect of mercuric ion (Hg2+) on the oxidant response and calcium ion (Ca2+) in the protoplasts of Arabidopsis thaliana. The protoplast cells were exposed to 5.0, 10.0, and 20.0 mmol/L Hg2+ for … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 29 Aug 2023 · 4,961 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Influence of Partial Substitution of Potassium by Sodium on the Growth Effect of SugarcaneChao Zheng, Yong-Xiang Huang, Jin Li et al.The effects of different potassium and sodium levels on the growth of Taisugar No. 22 (ROC22) were studied by potted nutrient solution-sand culture experiment in this paper. The results showed that under low potassium stress (0 mmol/L) supply, the proper application of sodium could significantly promote photosynthesis of sugarcane and dry matter accumulation, reduce root shoot ratio and promote shoot … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 12 Jun 2018 · 11,314 accessesView PDFCite
Research ArticleOpen accessIn the author namesExpression, Purification and Activity Assay of the Recombinant Protein of Catechol-O-Methyltransferase from Chinese White Shrimp (Fenneropenaeus chinensis)Dian-Xiang Li, Xin-Jun Du, Xiao-Fan Zhao, Jin-Xing WangProblem statement: We have previously cloned a gene of Chinese white shrimp Catechol O-Methyltransferase (designated Fc-COMT) and characterized the gene expression pattern. In this study, expression and purification as well as activity assay of the recombinant Fc-COMT was further conducted. Approach: Using pET-30a (+) as a prokaryotic expression vector, the recombinant Fc- COMT was expressed in the supernatant of Escherichia … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,770 accessesView PDFCite
