“…Plant diversity and soil factors were found to be vital in predicting microbial community changes in soil (Liu et al, 2020;Zeng et al, 2017;Zhang et al, 2016) Zhang et al, 2021;Zheng et al, 2019). Similarly, our research clearly revealed the importance of plant diversity and pH in promoting soil microbial community.…”

“…Plant diversity and soil factors were found to be vital in predicting microbial community changes in soil (Liu et al, 2020; Zeng et al, 2017; Zhang et al, 2016) and multifunctionality (Lucas‐Borja & Delgado‐Baquerizo, 2019; Xue et al, 2020). More and more researches have recently identified soil bacteria as a critical factor influencing soil multifunctionality (Delgado‐Baquerizo et al, 2020; Zhang et al, 2021; Zheng et al, 2019).

Plants and soil bacteria exert a vital function in mediating soil ecosystem multifunctionality (EMF). Nevertheless, plant and soil bacteria interaction during forest secondary succession is poorly understood, and their roles in soil EMF remain largely unexplored. The dynamics of soil physicochemical properties and bacterial diversity was studied in southwest China during forest succession from coniferous to monsoon broadleaf evergreen. Interdomain ecological networks (IDEN) were adopted for investigating plant–bacteria associations. With the purpose of assessing how soil factors, bacterial community and plant diversity influenced soil EMF, the structural equation model (SEM) was used. It was discovered that both soil bacterial diversity and soil EMF gradually increased with the succession. IDEN analysis revealed that plant–bacteria ecological networks differed significantly across successional stages. Keystone plant species richness (KSR) increased with succession, which benefited soil bacteria diversity (path coefficient = 0.802, p < 0.001) while having a direct negative impact on pH (path coefficient = −0.602, p < 0.05) and C:N (path coefficient = −0.759, p < 0.001). Soil pH and C:N ratio declines were observed during forest secondary succession and were found to be inversely related to soil EMF. Furthermore, soil pH was found to be inversely related to bacterial diversity. The SEM analysis explained 88.2% of the variation in soil multifunctionality. The findings suggested that keystone plant species played a key function in regulating the variations of soil bacterial community and EMF (total effect = 0.813). Our study clarified the critical functions of keystone species in driving soil bacterial diversity and multifunctionality during forest succession and provided a new perspective on the relationship between above‐ and below‐ground.

“…The heightened importance of fungi over bacteria in forest soils, potentially due to the presence of abundant recalcitrant substrates like lignin polymers, which are associated with the strong degradative capacity of fungi, may provide an explanation for this disparity. Interestingly, a prior study discovered that in agroecosystems, soil multifunctionality was jointly regulated by both bacterial and fungal communities [60]. This observation underscores the significance of adequate organic material inputs, which encompass a diverse array of both labile and recalcitrant carbon substrates, highlighting the interconnected role of both bacterial and fungal communities in shaping soil multifunctionality.…”

Soil nutrient transformation and the microbial metabolism are primarily regulated by soil microorganisms, including fungi and bacteria, which exhibit distinct growth patterns, energy substrate utilization, and survival strategies. Despite their significance, our understanding of the key microorganisms governing the soil microbial metabolism and multifunctionality in subtropical woodlands remains limited. To address this knowledge gap, we conducted a large-scale investigation and assessment of the soil microbial metabolic limitation and soil multifunctionality in Camellia oleifera Abel and Pinus massoniana Lamb. woodlands in subtropical China. Our results reveal that the microbial phosphorus limitation was more severe in C. oleifera compared to P. massoniana woodlands. Nonetheless, the pattern of carbon metabolic limitation for microbes and soil multifunctionality was similar in both types of woodland. Specifically, the microbial carbon limitation was positively associated with both bacterial and fungal richness, while the microbial phosphorus limitation was significantly correlated with fungi including the richness and community structure in the P. massoniana woodland. By contrast, we did not observe significant correlations between microbial metabolic limitation indices and microbial parameters in C. oleifera woodlands. Regarding soil multifunctionality, the results reveal a strong positive correlation between the soil multifunctionality and fungal community in both P. massoniana and C. oleifera woodlands. Furthermore, our structural equation modeling revealed that the soil fungal community, rather than the bacterial community, had a significant effect on the microbial metabolic limitation and soil multifunctionality. Overall, our study provides profound insights into the relative importance of bacterial and fungal communities in shaping the soil microbial metabolic limitation and soil multifunctionality in subtropical woodlands. The findings of our study have important implications for the management and conservation of subtropical woodlands.

“…Cereal–forage rotation presented little effects on rhizosphere microbial alpha diversity, but greater effects on beta diversity (Figures 1 and 2), which are consistent with previous results that despite lower microbial α‐diversity variations, obvious changes in β‐diversity could still be observed (Griffiths et al, 2011; Lozupone et al, 2007). The changes of microbial community composition could significantly promote plant production and soil multifunctionality (Li et al, 2021; Yan et al, 2022; Zhang et al, 2021). Some microbial groups shaped by rotation regime show strong effects on soil functions such as organic matter decomposition and nutrient cycling (D'Acunto et al, 2018; Fernandez et al, 2016; Nazaries et al, 2021).…”

Cereal–forage rotation is a crucial advantageous agricultural measure to accelerate sustainable agricultural development. However, the interaction mechanisms of crop productivity with soil characteristics and soil microbiome under this rotation regime remain controversial, leading to large uncertainties in assessing the stability of agroecosystems. The aim of this study is to investigate the effects of cereal–forage rotation on the rhizosphere microbial communities, soil properties, and crop productivity as well as the complex relationships among them. To achieve this, the rhizosphere soils of maize and alfalfa were collected from a field experiment with different cropping systems (rotation and monoculture systems of alfalfa or maize) to analyze the microbial communities and further to evaluate their roles on participating in soil nutrient cycling and improving crop productivity. Cereal–forage rotation significantly affected the microbial community compositions rather than diversities in rhizosphere soils, resulting in obvious changes of interspecific interactions. The increased alterations of crop productivity were more correlated with the shifts in bacterial community rather than fungal community, which was actuated by soil pH. Some bacterial recruitment under rotations was observed, primarily showing potential phosphorus cycling and nitrogen assimilation functions. Specifically, the accumulated beneficial rhizobacterial taxa included those with potential antagonistic activities (e.g., Brevundimonas, Gemmatimonas, Lysobacter, Pseudonocardia, and Pseudomonas) and positively responding to biological anabolism (e.g., Luteolibacter, Hyphomicrobium, and Sphingomonas). Such findings reveal that cereal–forage rotation could effectively shape rhizosphere soil microbial community structure and particularly lead to the recruitment of a group of salutary rhizobacteria, which would positively provide some valuable theoretical bases for the developments of high‐quality and high‐yield agriculture.
