“…Previous studies have found that GRSP compositional traits can be changed by Al 3+ ( Aguilera et al, ). Although pH‐dependent GRSP accumulation in soil is well documented ( Feng et al, ; Wang et al, ), few studies have focused on the relation between pH and GRSP compositional traits ( Wang et al, ). Our study was the first report to clarify the various soil properties possible influences on GRSP compositional traits from a large field dataset.…”

“…GRSP amount received increasing attention over the past few years for enhancing soil aggregate stability ( Rillig et al, ; Wu et al, ; Xie et al, ; Zhang et al, ) and loading capacity for heavy metals ( Wright and Upadhyaya , ), maintaining soil fertility, increasing soil C capture ( Rillig et al, ; Luna et al, ; Singh et al, ), and regulating soil acidity ( Cai et al, ; Wang et al, ; Zhang et al, ). Recent studies also show that GRSP has a complex composition of asparagine‐linked carbohydrate chains ( Wright et al, ; Wang et al, ), and it is a mixture of organic matter, amino acids and carbohydrates along with some aliphatic methines, methylenes ( Rillig et al, ), and possibly some auto‐fluorescent compounds tightly bound with metal ions ( Aguilera et al, ; Wang et al, ). However, limited information is available regarding GRSP compositional traits compared to GRSP amount, while there are few reports on the possible regulating function of GRSP compositional traits from various soil properties including soil fertility and physicochemical properties ( Wang et al, ; Wang et al, ; Zhang et al, ).…”

“…Auto‐fluorescence of fungal mycelium can be visualized using confocal laser scanning microscopy ( Aguilera et al, ), and a semi‐quantitative estimation of its composition can be determined by using a 3‐D fluorescence spectroscopy ( Roberts and Jones , ). X‐ray diffraction (XRD) can be used to determine soil colloids, crystallinity, grain size ( Li et al, ; Wang et al, ), and extractable protein structure ( Yuan and Xia , ). Furthermore, simple regression analysis, stepwise regression has been used to uncover associations among different ecological parameters, while structural equation models from IBM AMOS software have been proved to identify the causal relationship among soil microbial relations from direct and indirect effects identifications ( Eisenhauer et al, ).…”

Glomalin‐related soil protein (GRSP) is well‐known for its soil conditioning functions, but compositional traits are rarely considered. Farmland in northeastern China is the most important commercial grain basis, and soil degradation becomes the bottleneck for keeping crop productivity. The objective of this study was to uncover the possible associations between GRSP (amount and composition) and soil properties, and make suggestions for soil improvement from soil glomalin rehabilitation in northeastern China. Here, spatial variation in GRSP amount (Easily‐extractable‐GRSP, EE‐GRSP; Total‐GRSP, T‐GRSP) and its compositional traits from infrared spectroscopy, UV‐absorbance, X‐ray diffraction (XRD) and 3‐D fluorescence spectroscopy were surveyed in 360 soil samples across northeastern China, and their association with 11 soil properties were also analyzed for finding the possible influence of soil properties on GRSP composition in farmland. There about 3‐fold spatial variation in GRSP amount was observed, while functional group variations were ranged from 1.2‐fold (O–H & N–H stretching) to 2.4‐fold (C–O stretching & O–H bending of –COOH) in different locations. The XRD showed that grain size was 113–180Å and crystallinity was 0.71–1.42%, and GRSP contained seven fluorescent compounds of tyrosine‐like, tryptophan‐like, fulvic acid‐like, soluble microbial byproduct, humic acid‐like, nitrobenzoxadidole‐like, and calcofluor white‐like. Both, EE‐GRSP and T‐GRSP positively associated with soil organic carbon (SOC), soil N (SON), soil P (SOP), alkali‐hydrolyzed N (AN), available P (AP), available K (AK), and soil water, while negatively associated with soil pH and soil bulk density. Structural equation model (SEM) analysis indicates that direct effects on GRSP amounts were mainly from soil bulk density (coefficient: –0.27), soil pH (coefficients: –0.51 to –0.57), SOC (coefficients: 0.51 to 0.69) and AP (coefficients: 0.18 to 0.26), while all other soil properties had indirect effects on GRSP amounts via their close associations with these four parameters. Compared with the GRSP amounts, soil properties laid fewer effects on GRSP compositional traits. Of 16 compositional traits, five of them showed possible regulations from soil properties, which were three infrared functional groups (IR‐II: aliphatic C–H stretching; IR‐V: C–O stretching & O–H bending of –COOH; IR‐VII: O–H binding) and two fluorescent compounds (tyrosine‐like and humic acid‐like). SEM analysis indicates that soil water, pH and EC could directly affect IR‐II, IRV, tyrosine‐like and humic acid‐like, while available nutrients showed more evident influences on infra‐red functional groups than total amounts of N, P and K. Moreover, SOC, as a media of various soil nutrients, gave the strongest influence on GRSP compositional traits. As a supplement to previous studies, we found that GRSP is a mixture of different fluorescent compounds with different functional groups. Our findings highlight that soil properties could strongly change both GRSP accumulatio...

Arbuscular mycorrhizal fungi (AMF) is presumably to be associated with carbon sequestration and nutrient acquisition through mineral weathering in wetland ecosystems. However, information on AMF-carbonweathering interactions is limited. Grain size, concentrations of nutrients, and the major components of 304 surface sediment samples and glomalin-related soil protein (GRSP) in 133 surface sediment samples were analyzed in various environments, including the upper delta plain wetlands (UDPW) and its adjacent shallow sea wetlands (SSW), to evaluate the relationship among the GRSP, carbon content, nutrients, and chemical index of alteration (CIA) in the wetlands of the Liaohe Delta (LHD). The concentrations of GRSP in surface sediments ranged between~0.11 and 11.31 mg g −1 , with an average of 2.30 AE 0.17 mg g −1 , and were significantly affected by the vegetation types. The ratios of organic carbon in GRSP (GRSP-C) to soil organic carbon (SOC) varied from 0.71% to 25.34%, with an average of 10.34% AE 0.52%, indicating that the GRSP was an important carbon pool in sediments, and the carbon dynamics in these wetlands were closely related to human activities. Moreover, the CIA values ranged from~18.97 to 68.75, and were significantly higher in the UDPW than in the SSW (p < 0.05), and were significantly correlated with the concentrations of GRSP (r 2 = 0.22 [r = 0.43], p < 0.01). Meanwhile, both the CIA and GRSP were significantly correlated with SOC, Total Nitrogen, and Fe (r 2 > 0.17 [r > 0.41], p < 0.01). The results indicate that AMF excursions in wetland ecosystems enhance carbon sequestration and mineral weathering, and in turn they alter retention of at least some nutrients.
