doi:10.13304/j.nykjdb.2021.0645

Abstract

Abstract:

Selenium is a beneficial trace element for plants， and it plays an important role in plant growth and resistance. More and more studies have found that exogenous addition of selenium could effectively alleviate plant heavy metal stress， and related research have gradually deepened. This article summarized the relevant research on the absorption and transport accumulation of selenium by plants and the mechanism of selenium alleviating heavy metal stress in recent years， and compared the similarities and differences of selenium to different types of heavy metal stress mitigation mechanisms， and it can provide the theoretical basis for improving the ability of plants to resist heavy metal stress.

Key words: selenium, heavy metal stress, big data analysis, absorption and transport

摘要：
