Elements are the basic substances that make up living organisms, and the element composition in plants quantitatively reflect the adaptation of plants to environment. However, the drivers that constitute the species‐specific plant elementome, as well as the bivariate bioelemental correlations in determining the stability of different bioelements are yet unclear. Based on 1058 leaf observations of 84 plant species from 232 wetlands across large environmental gradients, we found that bioelements with higher concentration were more stable and evolutionary constrained. We proposed a stability of well‐coordinated elements hypothesis, suggesting that bioelements that coordinate well in driving certain physiological functions constrain each other, thus maintaining relatively stable ratios in plants. In contrast, those functionally independent bioelements fluctuate greatly with environmental nutrient availability. Cold and saline stresses decreased plant stoichiometric network connectivity, complexity, and stability. Our research filled the gap in study of wetland plant elementome, and provided new evidences of plant–environment interactions in regions sensitive to climate change.

生物元素之间的协调在湿地植物中诱导的宏量元素比微量元素更稳定


元素是构成生物体的基本物质，植物中的元素组成定量反映了植物对环境的适应。然而，构成物种特异性植物元素组的驱动因素，以及确定不同生物元素稳定性的二元生物元素相关性尚不清楚。基于在大环境梯度下对 232 个湿地的 84 种植物物种的 1058 片叶子观察，我们发现浓度较高的生物元素更稳定且受进化限制。我们提出了一个协调良好的元素稳定性假说，认为在驱动某些生理功能方面协调良好的生物元素相互约束，从而在植物中保持相对稳定的比例。相比之下，那些功能独立的生物元素会随着环境营养物质的可用性而大幅波动。寒冷和盐胁迫降低了植物化学计量网络的连通性、复杂性和稳定性。我们的研究填补了湿地植物元素组研究的空白，并为对气候变化敏感的地区植物-环境相互作用提供了新的证据。
