Abstract

Phytoremediation is a promising technology that uses plants and their associated microbes to clean up contaminants from the environment. In recent years, phytoremediation assisted by plant growth-promoting bacteria (PGPB) has been highly touted for cleaning up toxic metals from soil. PGPB include rhizospheric bacteria, endophytic bacteria and the bacteria that facilitate phytoremediation by other means. This review provides information about the traits and mechanisms possessed by PGPB that improve plant metal tolerance and growth, and illustrate mechanisms responsible for plant metal accumulation/translocation in plants. Several recent examples of phytoremediation of metals facilitated by PGPB are reviewed. Although many encouraging results have been reported in the past years, there have also been numerous challenges encountered in phytoremediation in the field. To implement PGPB-assisted phytoremediation of metals in the natural environment, there is also a need to critically assess the ecological effects of PGPB, especially for those nonnative bacteria.

植物生长促进菌在金属植物修复中的作用。

植物修复是一种利用植物及其相关微生物清除环境污染物的技术。近年来，植物生长促进菌(plant growth-promoting bacteria, PGPB)辅助植物修复技术被广泛应用于土壤中有毒金属的清除。PGPB包括根际细菌、内生细菌和通过其他方式促进植物修复的细菌。本文综述了PGPB改善植物金属耐受性和生长的特性和机制，并阐明了植物金属积累/转运的机制。综述了近年来植物修复金属的几个实例。虽然在过去的几年里已经报道了许多令人鼓舞的结果，但在该领域的植物修复也遇到了许多挑战。为了实现PGPB对自然环境中金属的植物修复，还需要严格评估PGPB的生态效应，特别是对那些非本地细菌的生态效应。

期刊介绍： Advances in Microbial Physiology publishes topical and important reviews, interpreting physiology to include all material that contributes to our understanding of how microorganisms and their component parts work. First published in 1967, the editors have always striven to interpret microbial physiology in the broadest context and have never restricted the contents to traditional views of whole cell physiology.
