“…In accordance with the results observed in this work, the CM at the highest water regimes (L96 and L68) is similar in wheat grown under different management systems, under temperate climate condition (Galazka et al, 2018) and is also within the average observed (41%) in a study that evaluated CM in 94 wheat genotypes (Lehnert et al, 2017).…”

Mycorrhizal association contributes to plant growth, influencing tolerance to abiotic stresses such as water deficit. There is considerable variation in infection by arbuscular mycorrhizal fungi (AMF) in cultivars of the same crop, but there is little information regarding these differences in wheat. The objective of this work was to evaluate the influence of water deficit on the arbuscular mycorrhizal association in wheat genotypes in the Cerrado region and the association between soil attributes and mycorrhizal colonization. The experiment was conducted in a no-till system, using different water regimes. The experimental design was a randomized block with subdivided plots scheme, with 12 treatments and 3 repetitions. The plots consisted of 4 wheat genotypes and the subplots included 3 water regimes. Mycorrhizal colonization, soil microbial biomass carbon, total soil organic carbon, easily extractable glomalin-related soil protein, spore number and AMF species diversity were evaluated. Mycorrhizal colonization was not influenced by wheat genotypes, but it was favored by the higher water regime, being 44.8% higher when compared to the lower water regime. The soil moisture was positively correlated with the soil attributes with the exception of the number of AMF spores. The community of AMF associated with wheat genotypes was similar, comprising of 12 species, predominantly Claroideoglomus etunicatum and Glomus macrocarpum. The low variation among wheat genotypes for AMF diversity suggests no selective influence of the plants on the AMF community in the area of the study. Water regime was shown to be a dominant factor in mycorrhizal association.

“…These results suggest that GRRP is more directly related to soil GRSP and mediates SOC stock by influencing GRSP storage in the soil. Indeed, an increase of SOC with increasing GRSP and the contribution of GRSP to SOC dynamics are well documented (Anna et al, 2018; Singh, Rai, et al, 2017; Singh, Zhu, et al, 2020). Furthermore, our multivariate analysis demonstrated a better interconnection among these measured variables by projecting them in a two‐dimensional plane derived from the two most higher‐ranked PCA components (Figure 6).…”

Effect of root‐glomalin on soil carbon storage in trees' rhizosphere and interspace of a tropical dry forest

Increasing soil organic carbon (SOC) concentration is a desirable aspect of afforestation. Glomalin‐related soil protein (GRSP) is a ubiquitous component of SOC, preferentially produced by arbuscular mycorrhizal fungi (AMF) during symbiotic association with the plant roots. Although the role of AMF in GRSP production is well established, the role of root in GRSP production is not yet clear. Hence, we aimed to assess the glomalin in different tree roots (i.e., glomalin‐related root protein; GRRP) and its influence on GRSP and SOC storage in trees’ rhizosphere and interspace. The experiment was conducted in a tropical dry forest (India) with six native trees (Hardwickia binata, Lagerstroemia parviflora, Diospyros melanoxylon, Terminalia tomentosa, Shorea robusta, and Anogeissus latifolia) and a planted Teak (Tectona grandis). The fine roots (from the rhizosphere) and topsoils (0–15 cm) were collected from the rhizosphere and interspace of each tree. We found GRRP concentration varying between trees, with higher values observed in the roots of native trees than those of Teak. The AMF colonization was positively correlated with GRRP (r2 = 0.88), and GRRP positively correlated with GRSP and SOC. The higher correlation of GRRP was observed with GRSP (r2 = 0.70–0.79) compared with SOC (r2 = 0.56–0.58), while the correlation was much stronger between GRSP and SOC (r2 = 0.91). These results indicate that GRRP influences SOC storage via mediating GRSP concentration. We suggest that GRRP can be used as an indicator for species screening during afforestation with the aim to improve SOC storage on an afforested landscape.

“…In ecological systems, there are also observed well organized fungi communities (Wittwer et al 2018). The research on the glomalin content of the soil, which is glycoproteins produced by arbuscular mycorrhizal (AM) fungi, has shown a higher content of these proteins in soils from organic farming compared to soils from conventional and integrated systems, and also from winter wheat monocultures (Gałązka et al 2018). This indicates a higher activity of AM fungi in these soils.…”

<p>All over the world, including Poland, interest in the organic farming is growing. It is based on an attempt to minimize human impact on the environment while maintaining the natural functionality and productivity of the agricultural system. At the same time, every human activity in the natural environment results in greater or lesser changes in the soil ecosystem. Organic farming also has an impact on physical and chemical parameters and soil biological activity. These changes should be monitored and considered in the context of long-term land management. This review focuses on the impact of the organic farming system on soil biological activity and diversity of soil microorganisms.</p>
