Abstract

(L.) Ledebour is a perennial facultative halophyte species from the Malvacea family that grows in coastal areas with high amounts of salt. The tolerance of to the high concentration of salt (0.5-1.5% salinity range of coastal saline land) has been widely studied for decades. Nowadays, with the dramatic development of the economy and urbanization, in addition to the salt, the accumulation of mate(loid)s in coastal soil is increasing, which is threatening the survival of halophyte species as well as the balance of wetland ecosystems. Recently, the capacity of to cope with either single heavy metal stress or a combination of multiple meta(loid) toxicities was studied. Hence, this review focused on summarizing the physiological and biochemical behaviors of that has been simultaneously exposed to the combination of several meta(loid) toxicities. How the salt accumulated by impacts the response to meta(loid) stress was discussed. We conclude that as a potential candidate for phytoremediation, was able to cope with various environmental constrains such as multiple meta(loid) stresses due to its relative tolerance to meta(loid) toxicity.

摘要

(L.) Ledebour是锦葵科的一种多年生兼性盐生植物,生长在盐分含量高的沿海地区。几十年来,人们对其在高浓度盐分(沿海盐碱地0.5 - 1.5%盐度范围)下的耐受性进行了广泛研究。如今,随着经济和城市化的迅猛发展,除了盐分之外,沿海土壤中金属(类金属)的积累也在增加,这正威胁着盐生植物物种的生存以及湿地生态系统的平衡。最近,人们研究了其应对单一重金属胁迫或多种金属(类金属)毒性组合的能力。因此,本综述着重总结了其同时暴露于几种金属(类金属)毒性组合下的生理和生化行为。讨论了其积累的盐分如何影响对金属(类金属)胁迫的响应。我们得出结论,作为植物修复的潜在候选者,由于其对金属(类金属)毒性具有相对耐受性,(L.) Ledebour能够应对各种环境限制,如多种金属(类金属)胁迫。
