气候变化导致的极端天气事件，加上气温升高、土壤条件恶劣、水的可用性和质量低下，以及许多人为污染物的引入，给植物带来了独特的挑战。虽然我们对植物对这些单独条件的反应了解很多，但我们对许多因素同时发生的组合，即多因子胁迫组合，是如何影响植物的知之甚少。研究了拟南芥野生型和不同突变体的幼苗在6种不同的低胁迫条件下的多因子胁迫组合，并测定了它们的存活、生理和分子反应。我们的研究结果表明，虽然单独施加每种不同的胁迫对植物生长和存活的影响可以忽略不计，但多因子胁迫组合对植物的累积影响是有害的。我们进一步表明，植物对多因子胁迫组合的响应是独特的，特定的途径和过程在植物对多因子胁迫组合的适应中起着关键作用。综上所述，我们的研究结果表明，进一步污染我们的环境可能导致多因素压力组合的复杂性更高，从而可能导致植物生长和生存的严重下降。
Climate change‐driven extreme weather events, combined with increasing temperatures, harsh soil conditions, low water availability and quality, and the introduction of many man‐made pollutants, pose a unique challenge to plants. Although our knowledge of the response of plants to each of these individual conditions is vast, we know very little about how a combination of many of these factors, occurring simultaneously, that is multifactorial stress combination, impacts plants. Seedlings of wild‐type and different mutants of Arabidopsis thaliana plants were subjected to a multifactorial stress combination of six different stresses, each applied at a low level, and their survival, physiological and molecular responses determined. Our findings reveal that, while each of the different stresses, applied individually, had a negligible effect on plant growth and survival, the accumulated impact of multifactorial stress combination on plants was detrimental. We further show that the response of plants to multifactorial stress combination is unique and that specific pathways and processes play a critical role in the acclimation of plants to multifactorial stress combination. Taken together our findings reveal that further polluting our environment could result in higher complexities of multifactorial stress combinations that in turn could drive a critical decline in plant growth and survival.
