ABSTRACT
Cardamine violifolia O. E. Schulz is a cruciferous plant, and it is mainly found in Enshi, Yichang, Hubei Province and Hupingshan, Hunan Province, China. Cardamine violifolia has the best ability for selenium (Se) accumulation and can accumulate Se up to 8000, 2000, and 2300 mg/kg in roots, stems, and leaves, respectively. The plant has high medicinal value and can also be used as raw material for processing into Se food products, which has a great potential for future development. This chapter explains the study of response changes of enzymatic detoxification mechanisms under selenate stress in Cardamine violifolia to provide additional information for cultivating this plant species. CAT and glutathione peroxidase played a key role under the condition of sodium selenate stress in the physiological regulation enzyme system of plant leaves, which provides new information on cultivating Cardamine violifolia in Se-rich soils.
