“…The reason for this could be that bacterial species or strains are capable of optimal growth only within a narrow pH range (Lauber, Hamady, Knight, & Fierer, ; Ramirez, Craine, & Fierer, ), such that changes in environmental pH would directly deterministically select for species with different pH optima. Besides, soil pH usually covaries with other environmental variables such as climate, soil nutrients, plant properties, and the content or valence state of heavy metal elements (Van Nostrand, Sowder, Bertsch, & Morris, ; Williams, Jangid, Shanmugam, & Whitman, ; Wang, Zheng, et al, ; Lammel et al, ; Appendix Table A6). Hence, increased soil pH difference could result in the shift of the assembly processes, especially for VS, which increased steadily with spatial scale (Appendix Figure A6).…”

Interpreting distance‐decay pattern of soil bacteria via quantifying the assembly processes at multiple spatial scales

It has been widely accepted that there is a distance‐decay pattern in the soil microbiome. However, few studies have attempted to interpret the microbial distance‐decay pattern from the perspective of quantifying underlying processes. In this study, we examined the processes governing bacterial community assembly at multiple spatial scales in maize fields of Northeast China using Illumina MiSeq sequencing. Results showed that the processes governing spatial turnover in bacterial community composition shifted regularly with spatial scale, with homogenizing dispersal dominating at small spatial scales and variable selection dominating at larger scales, which in turn explained the distance‐decay pattern that closer located sites tended to have higher community similarity. Together, homogenizing dispersal and dispersal limitation resulting from geographic factors governed about 33% of spatial turnover in bacterial community composition. Deterministic selection processes had the strongest influence, at 57%, with biotic factors and abiotic environmental filtering (mainly imposed by soil pH) respectively contributing about 37% and 63% of variation. Our results provided a novel and comprehensive way to explain the distance‐decay pattern of soil microbiome via quantifying the assembly processes at multiple spatial scales, as well as the method to quantify the influence of abiotic, biotic, and geographic factors in shaping microbial community structure, thus enabling understanding of widely acknowledged microbial biogeographic patterns and microbial ecology.

“…Part of G × E interactions that is linked to specific environmental factors such as soil type, climatic conditions, crop management, or microbial communities can be utilized in breeding for local adaptation (Annicchiarico, Bellah, & Chiari, ; Busby et al, ). Likewise, breeding more diverse cropping systems (e.g., mixed cropping, intercropping, undersowing) that harbour and maintain greater microbial diversity (Chave, Tchamitchian, & Ozier‐Lafontaine, ; Granzow et al, ; Lori, Symnaczik, Mäder, De Deyn, & Gattinger, ; Wang, Zheng, et al, ) will foster selection for beneficial plant microbe interaction.…”

“…Replacing this biologically fixed N by mineral fertilizer would cost up to an estimate of $10 billion per year worldwide (Graham & Vance, ). Leguminous crops are also valuable partners in various intercropping systems throughout the world, providing a means of diversification of cropping systems (Taschen et al, ; Wang et al, ). Recently, Reckling et al () showed that replacing mineral fertilizer with legumes in European cropping systems substantially reduces environmental impact in terms of nitrate leaching and nitrous oxide emissions while maintaining economic profitability of the system.…”

Root and foot diseases severely impede grain legume cultivation worldwide. Breeding lines with resistance against individual pathogens exist, but these resistances are often overcome by the interaction of multiple pathogens in field situations. Novel tools allow to decipher plant-microbiome interactions in unprecedented detail and provide insights into resistance mechanisms that consider both simultaneous attacks of various pathogens and the interplay with beneficial microbes. Although it has become clear that plant-associated microbes play a key role in plant health, a systematic picture of how and to what extent plants can shape their own detrimental or beneficial microbiome remains to be drawn. There is increasing evidence for the existence of genetic variation in the regulation of plant-microbe interactions that can be exploited by plant breeders. We propose to consider the entire plant holobiont in resistance breeding strategies in order to unravel hidden parts of complex defence mechanisms. This review summarizes (a) the current knowledge of resistance against soil-borne pathogens in grain legumes, (b) evidence for genetic variation for rhizosphere-related traits, (c) the role of root exudation in microbe-mediated disease resistance and elaborates (d) how these traits can be incorporated in resistance breeding programmes.

“…The biomass C/N ratio increased from 6.4 to 8.0 and C/P ratio from 20.0 to 26.6. Inorganic fertilization had a drastic effect on microbial biomass and lower amount of soil microbial biomass in inorganic fertilized soils was reported by many workers (Wang et al, 2017). Wallenstein et al, (2006) andTreseder, (2008) found that chemical fertilized addition lowered microbial biomass carbon by 40-59 and 15% respectively and that total N had related negatively with biomass carbon in both mineral and organic soils.…”

A study of organic, integrated and inorganic plant nutrient management systems was conducted to determine the effect of management practices on soil microbiological properties after 10 years of continuous application. The rate of C mineralization and potentially mineralizable nitrogen were 6.8 and 41.5 mg/kg soil, respectively. Arginine ammonification and nitrification activities were 0.88 µg NH 4 + -N/g soil/h and 56.0 µg NO 3--N/g/day, respectively. Microbial biomass C, N and P were 320, 40 and 12 mg/kg soil, respectively. Alkaline phosphatase, urease and cellulase activities were highest with application of VC@15t /ha.
