摘要

葡聚糖相关土壤蛋白质(GRSP)是一种潜在的丛枝菌根真菌(AMF)副产品,也是被动土壤有机碳(SOC)池的主要贡献者。尽管GRSP在SOC储存中起着至关重要的作用,但我们对其对人为全球变化因素(GCFs)的响应却知之甚少。在此,我们利用来自 107 项主要研究的 530 项观测数据,进行了一项全球荟萃分析,以揭示多种全球变化因素(气候变化、植物入侵、野火、城市化、土地利用变化和养分添加(氮、磷、钾))对陆地生态系统中两种功能性 GRSP 部分(易提取 GRSP 和总 GRSP)的影响。我们发现,二氧化碳浓度升高使 T-GRSP 增加了 28%,氮磷钾综合添加量增加了 39.9%,氮磷钾添加量增加了 29.5%。气候变暖和单独增加氮分别使EE-GRSP增加了2.4%和13.6%,但对T-GRSP没有影响。然而,城市化和干旱则分别使T-GRSP减少了26%和15%。从自然生态系统到耕地的土地利用变化使 T-GRSP 减少了 40%,而在耕地上植树造林则使 T-GRSP 增加了 32%。其他 GCFs(PI、野火和 P)对 GRSP 的影响并不显著,这可能是因为:(i) AMF 活性发生了微小变化;(ii) 相反过程抵消了影响。在潮湿条件下和富含粘土的土壤中,如果在中长期(3-10+年)内以较高的强度施用 GCF,则 GCF 的影响非常显著。在土地利用变化过程中,沙质土壤的 T-GRSP 损失更大。T-GRSP的增加与AMF根系定植、土壤平均重量直径和SOC含量呈正相关。此外,我们的结构方程模型证实,GCF 通过改变 AMF-GRSP 产量直接影响 SOC,并间接影响土壤团聚体的形成和保护,这表明优化 GRSP 产量可以提高 SOC 固碳效果。

Unraveling the impact of global change on glomalin and implications for soil carbon storage in terrestrial ecosystems
Glomalin-related soil protein (GRSP) is a potential byproduct of arbuscular mycorrhizal fungi (AMF) and a major contributor to the passive soil organic carbon (SOC) pool. Despite its crucial role in SOC storage, we know little about the response of GRSP to anthropogenic global change factors (GCFs). Here, using 530 observations from 107 primary studies, we conducted a global meta-analysis to unravel the effects of multiple GCFs (climate change, plant invasion (PI), wildfire, urbanization, land-use change (LUC), and nutrient addition (nitrogen; N, phosphorus; P, and potassium; K) on two functional GRSP fractions (easily extractable- (EE-) and total- (T-) GRSPs) in terrestrial ecosystems. We found that elevated carbon-dioxide increased T-GRSP by 28%, combined NP addition by 39.9%, and NPK addition by 29.5%. Climate warming and alone N addition increased EE-GRSP solely by 2.4% and 13.6%, respectively, but did not influence T-GRSP. However, urbanization and drought decreased T-GRSP by 26% and 15%, respectively. The LUC from natural ecosystems to cropland decreased T-GRSP by 40%, while afforestation in croplands increased it by 32%. Other GCFs (PI, wildfire, and P) had non-significant effects on GRSP probably because of (i) minor changes in AMF activity and (ii) the counterbalancing of effects by opposite processes. GCF impacts were robust when applied at higher intensities for medium-to-long durations (3–10+ years) in humid conditions and clay-rich soils. The sandy soils experienced greater T-GRSP losses during LUC. Increases in T-GRSP were positively correlated with AMF-root colonization, soil mean-weight diameter, and SOC content. Further, our structure equation model confirmed that GCFs directly influence SOC by altering AMF-GRSP production and indirectly affecting soil aggregate formation and protection, suggesting that optimizing GRSP production can enhance SOC sequestration.
