“…Speci cally, pH, TN concentration, and Mg 2+ concentration are signi cantly positively correlated with myxobacteria community diversity; conversely, Ca 2+ and NH 4 + -N concentrations in compost manure were signi cantly and negatively correlated with myxobacteria community diversity. pH is the major abiotic factor in uencing the distribution of microorganisms in different environments [35][36][37][38]. Similarly, pH considerably in uenced myxobacteria distribution in compost manure in the present study.…”

Myxobacteria are unique predatory microorganisms with a distinct social lifestyle. The associated taxa play key roles in the microbial food webs in different ecosystems and regulate the community structures of soil microbial communities. Compared with conditions under conventional management, under organic conditions, myxobacteria abundance increases in the soil, which could be related to the presence of abundant myxobacteria in the applied compost manure. In the present study, high-throughput sequencing technologies were used to investigate the distribution patterns and drivers of predatory myxobacteria community distribution patterns in four common compost manures. According to the results, there was a significant difference in predatory myxobacteria community structure among different compost manure treatments (P < 0.05). The alpha-diversity indices of myxobacteria community under swine manure compost were the lowest (Observed OTU richness = 13.25, Chao1 = 14.83, Shannon = 0.61), and those under wormcast were the highest (Observed OTU richness = 30.25, Chao1 = 31.65, Shannon = 2.62). Bacterial community diversity and Mg2+ and Ca2+ concentrations were the major factors influencing myxobacteria distribution patterns under different compost manure treatments. In addition, pH, total nitrogen, and organic carbon influenced myxobacteria distribution in compost manure. The predator–prey relationship between prey bacteria and myxobacteria and the interaction between myxobacteria and specific bacterial taxa (Micrococcales) in compost manure could explain the influence of bacteria on myxobacteria community structure. Further investigations on the in-situ distribution patterns of predatory myxobacteria and the key bacteria influencing their distribution are would advance our understanding of the ecological distribution patterns and functions of predatory microorganisms in the microbial world.

“…The edaphic condition is one of the main factors affecting AM fungal community composition [51,52]. Soil pH has been clearly identified as one of the most important abiotic drivers of AM fungal communities [28,53]. pH directly influences the availability of Ca, Mg, and P in soil.…”

“…In soils with a low pH, P became particularly less available as it is sorbed in insoluble compounds [54]. Some specific AM fungi are commonly associated with acid soils, such as Acaulosporaceae, and some Glomeraceae, such as Rhizophagus manihotis [28,55]. Particularly, Rhizophagus manihotis is commonly associated with acidic poor-nutrient soils [56,57].…”

Arbuscular Mycorrhization in Colombian and Introduced Rubber (Hevea brasiliensis) Genotypes Cultivated on Degraded Soils of the Amazon Region

Rubber (Hevea brasiliensis, (Willd. Ex Adr. de Juss) Muell. Arg, Euphorbiaceae) is an important commercial latex-producing plant. Commercially, rubber is reproduced from a limited number of grifting genotypes. New promising genotypes have been selected to replace traditional genotypes. In addition, rubber has been promoted to recuperate Amazon soils degraded by extensive cattle ranching. Arbuscular mycorrhizal (AM) symbiosis is an important alternative for improving plant nutrition in rubber trees and recuperating degraded soils, but AM fungal communities on different plantations and in rubber genotypes are unknown. Spore abundance, root colonization and AM fungal community composition were evaluated in rubber roots of Colombian and introduced genotypes cultivated in degraded soils with different plantation types. Traditional (spore isolation and description; clearing and staining roots) and molecular techniques (Illumina sequencing) were used to assess AM fungi. Rubber roots hosted a diverse AM fungal community of 135 virtual taxa (VT) in 13 genera. The genus Glomus represented 66% of the total AM fungal community. Rubber genotype did not affect the arbuscular mycorrhization, hosting similar AM fungal communities. The composition of the AM fungal community on old and young rubber plantations was different. Diversity in AM fungi in rubber roots is an important characteristic for restoring degraded soils.

Temperature and pH define the realised niche space of arbuscular mycorrhizal fungi

Abstract: The arbuscular mycorrhizal (AM) fungi are a globally distributed group of soil organisms that play critical roles in ecosystem function. However, the ecological niches of individual AM fungal taxa are poorly understood.
