Abstract

Background and aims

Plant functional traits are key parameters of plant adaptation strategies to environmental changes and exhibit strong correlations with microbes. However, the differences in these relationships among plants with different resource strategies, particularly in relation to microbial eco-strategies, are not well understood.

Methods

We conducted a study on 18 whole-plant traits of 15 species and investigated the soil microbial characteristics across diverse environmental conditions on the eastern Qinghai Tibetan Plateau. To discern the differences between plants with acquisitive strategy (PAS) and those with conservative strategy (PCS), we examined the coordination of traits and their relationships with environmental factors and the soil microbial diversity, composition and life-history strategy.

Results

15 species adopted different resource strategies: two belonged to PAS, six to PCS, and seven to intermediate-strategy. PAS traits exhibited closer interactions and were more constrained by environmental conditions compared to PCS. Conversely, PCS traits were more closely associated with soil microbial diversity, composition and life-history strategy.

Conclusions

The differences in the associations of PAS and PCS traits with environmental conditions and microbial communities provides a fresh perspective for understanding diverse performance of plant resource strategies. Our findings indicate that a trait-based framework may be an optimal approach to explore plant–microbe interactions.

植物性状与环境和微生物之间的关系因植物资源策略的不同而不同

背景与目的植物功能性状是植物适应环境变化的关键参数，与微生物有很强的相关性。然而，不同资源策略的植物之间这些关系的差异，特别是与微生物生态策略有关的差异，尚未得到很好的理解。方法对青藏高原东部地区15种植物的18个全植物性状进行了研究，并对不同环境条件下的土壤微生物特征进行了研究。为了区分具有获取策略（PAS）和保守策略（PCS）的植物之间的差异，我们研究了这些性状的协调性及其与环境因子、土壤微生物多样性、组成和生活史策略的关系。结果15种植物采用不同的资源策略，其中2种为PAS策略，6种为PCS策略，7种为中间策略。与PCS相比，PAS性状表现出更密切的相互作用，受环境条件的约束更大。相反，PCS性状与土壤微生物多样性、组成和生活史策略的关系更为密切。结论PAS和PCS性状与环境条件和微生物群落的相关性差异为理解植物资源策略的多样性提供了新的视角。我们的研究结果表明，基于性状的框架可能是探索植物与微生物相互作用的最佳方法。

期刊介绍： Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
