植物对重金属等环境污染物的反应是通过触发基因的表达来编码参与应激反应的蛋白质。有毒金属离子通过干扰新生或非天然蛋白质的折叠过程和聚集，导致细胞活力下降，从而深刻影响细胞蛋白质稳态。然而，植物拥有一系列无处不在的细胞监视系统，使它们能够有效地解毒重金属，以增强对金属胁迫的耐受性。由于蛋白质是活细胞的主要组成部分，因此细胞质中金属离子与植物螯合素和金属硫蛋白的螯合以及液泡中金属的区室化以及应激损伤蛋白的修复或无法达到其天然构象的蛋白质的去除和降解对于植物耐受重金属胁迫至关重要。本文综述了植物细胞蛋白与重金属耐受性相关的研究进展。我们还讨论了植物如何在这种反复无常的环境中维持功能和健康的蛋白质组。
Plants respond to environmental pollutants such as heavy metal(s) by triggering the expression of genes that encode proteins involved in stress response. Toxic metal ions profoundly affect the cellular protein homeostasis by interfering with the folding process and aggregation of nascent or non-native proteins leading to decreased cell viability. However, plants possess a range of ubiquitous cellular surveillance systems that enable them to efficiently detoxify heavy metals toward enhanced tolerance to metal stress. As proteins constitute the major workhorses of living cells, the chelation of metal ions in cytosol with phytochelatins and metallothioneins followed by compartmentalization of metals in the vacuoles as well as the repair of stress-damaged proteins or removal and degradation of proteins that fail to achieve their native conformations are critical for plant tolerance to heavy metal stress. In this review, we provide a broad overview of recent advances in cellular protein research with regards to heavy metal tolerance in plants. We also discuss how plants maintain functional and healthy proteomes for survival under such capricious surroundings.
