Abstract

Recent years have seen a flurry of research activity concerning the hyperaccumulation of heavy metals by plants. Much of the interest in hyperaccumulation has been fueled by the commercial potential of phytoremediation, the use of plants to clean up contaminated soils (Baker et al., 1994; Salt et al., 1995; Chaney et al., 1997, 2000). These applications have in turn spurred many studies of the genetics and physiology of metal uptake (e.g. Krämer et al., 1996; Lasat et al., 1996; Salt & Krämer, 1999; Baker et al., 2000; see also Krämer, 2000; Lombi et al., 2000). Although phytoremediation provides an intriguing and potentially profitable backdrop, the ecology and evolution of hyperaccumulation in natural populations are interesting subjects in their own right. Two papers in this issue (Ghaderian et al., pp. 219-224; Davis & Boyd, pp. 211-217) are exciting contributions to the growing consensus that hyperaccumulation may act as a defense against herbivores and pathogens, and suggest that hyperaccumulation may become a model system for research in this area.

摘要

近年来,关于植物对重金属的超积累,已有一系列研究活动。植物修复(即利用植物清理受污染土壤)的商业潜力激发了人们对超积累的极大兴趣(贝克等人,1994年;索尔特等人,1995年;查尼等人,1997年、2000年)。这些应用反过来又促使人们对金属吸收的遗传学和生理学进行了许多研究(例如,克雷默等人,1996年;拉萨特等人,1996年;索尔特和克雷默,1999年;贝克等人,2000年;另见克雷默,2000年;隆比等人,2000年)。尽管植物修复提供了一个有趣且可能有利可图的背景,但自然种群中超积累的生态学和进化本身就是有趣的研究课题。本期的两篇论文(加德里安等人,第219 - 224页;戴维斯和博伊德,第211 - 217页)对越来越多的共识做出了令人兴奋的贡献,即超积累可能作为对食草动物和病原体的一种防御机制,并表明超积累可能成为该领域研究的一个模型系统。
