植物根系分泌物在重金属胁迫下的响应研究进展

Research Advances on Plant Root Exudates in Response to Heavy Metal Stress

植物在遭受重金属胁迫时,会改变根系分泌物的分泌情况来响应重金属胁迫。根系分泌物的变化与植物种类、重金属类型等多种因素有关。本文综述了重金属胁迫下,植物根系分泌物中有机酸、氨基酸、可溶性糖的变化以及这些组分的作用,为研究植物对重金属的耐受性和适应性,以及明确各组分的响应机制,提供理论依据。

In response to heavy metal stress plants alter the root exudate secretion in ways depending on the plant species and type of heavy metals, among other factors. This article reviews the published literature on the organic acids, amino acids, and soluble sugars in root exudates and their roles in the chemistry and physiology of the plants under varieties of heavy metal stresses. The referred material and documents concerning the tolerance and adaptability of plants to heavy metals as well as the response mechanisms involving the key chemicals would provide a concise and update information for the scientists interested in the field of study.
