Abstract
Aluminum (Al) toxicity is a major factor limiting plant productivity. The objective of the present study was to develop the mechanisms of boron (B) alleviating aluminum toxicity in citrus. The results showed that aluminum toxicity severely hampered root elongation. Interestingly, under aluminum exposure, boron supply improved superoxide dismutase activity while reducing peroxidase, catalase and polyphenol oxidase activities. Likewise, the contents of H2O2, lipid peroxidation, protein and proline in roots were markedly decreased by boron application under aluminum exposure. Our results demonstrated that boron could alleviate aluminum toxicity by regulating antioxidant enzyme activities in the roots.
期刊介绍:
Journal of Environmental Science and Health, Part C: Environmental Carcinogenesis and Ecotoxicology Reviews aims at rapid publication of reviews on important subjects in various areas of environmental toxicology, health and carcinogenesis. Among the subjects covered are risk assessments of chemicals including nanomaterials and physical agents of environmental significance, harmful organisms found in the environment and toxic agents they produce, and food and drugs as environmental factors. It includes basic research, methodology, host susceptibility, mechanistic studies, theoretical modeling, environmental and geotechnical engineering, and environmental protection. Submission to this journal is primarily on an invitational basis. All submissions should be made through the Editorial Manager site, and are subject to peer review by independent, anonymous expert referees. Please review the instructions for authors for manuscript submission guidance.
