摘 要:硒是植物的有益元素,植物对硒的吸收与外源硒的有效性、硒的形态、植物的种类等有关;硒在植物中主要以有机硒形态存在,HPLC-ICP-MS 联用已成为植物体内硒形态鉴定的最常用手段;含硒蛋白是植物体内最主要的有机大分子硒,具有抗肿瘤、抗氧化等多种生物活性。在环境安全和人类健康等方面,富硒植物具有很好的应用价值,所以利用分子生物学手段分析富硒植物的富硒机制,可以为富硒基因的筛选和利用提供理论依据。
关键词:硒;植物;硒形态;含硒蛋白
 
Study of plant selenium and selenium-containing protein

(Key Laboratory of Biological Resources Protection and Utilization of Hubei Province,
Abstract: Selenium is a beneficial element for plants, whose absorption of selenium is associated with effectiveness of exogenous selenium, forms of selenium and variety of plants etc. Selenium exists in plants mainly in organic forms. Jointly application of HPLC-ICP-MS has already become the most common measure for measuring different selenium forms inside plants and Se-containing protein is the principle organic macromolecule form, which has multiple bioactivities, like anti-tumor and anti-oxidation, etc. Selenium-enriched plant exhibits practical application value on environment safety and human health. Therefore, theoretical basis for screening and utilizing of selenium-enriched genes could be furnished by utilizing molecular biology measure to analyze the selenium-enriched mechanism of seleniumenrich plants.
Key words: selenium; plant; selenium forms; selenium-containing protein
