“…members can not only stimulate induced systemic resistance (ISR) of the host plant and produce antibiotics to suppress pathogens, but also secrete secondary metabolites to promote growth or to enhance abiotic stress tolerance of the host plant [7] , [8] . However, these functions depend on the abiotic conditions and the biological interactions for these members to exert their plant beneficial properties in a rhizosphere community with high species diversity [9] , [10] . To achieve a more comprehensive understanding of how to make full use of the plant beneficial functions of rhizosphere microorganisms, first, it is important to characterize the principles that govern the assembly process and drive the diversity and composition of the rhizosphere microbiome.…”

Environmental pressure to reduce our reliance on agrochemicals and the necessity to increase crop production in a sustainable way have made the rhizosphere microbiome an untapped resource for combating challenges to agricultural sustainability. In recent years, substantial efforts to characterize the structural and functional diversity of rhizosphere microbiomes of the model plant Arabidopsis thaliana and various crops have demonstrated their importance for plant fitness. However, the plant benefiting mechanisms of the rhizosphere microbiome as a whole community rather than as an individual rhizobacterium have only been revealed in recent years. The underlying principle dominating the assembly of the rhizosphere microbiome remains to be elucidated, and we are still struggling to harness the rhizosphere microbiome for agricultural sustainability. In this review, we summarize the recent progress of the driving factors shaping the rhizosphere microbiome and provide community-level mechanistic insights into the benefits that the rhizosphere microbiome has for plant fitness. We then propose the functional compensatory principle underlying rhizosphere microbiome assembly. Finally, we suggest future research efforts to explore the rhizosphere microbiome for agricultural sustainability.

“…Invasive species such as C. dactylon and Microstegium vimineum can change the soil chemistry, nitrogen cycle, and fire regimes, with resulting impacts on native biodiversity (Sindhu et al ., 2017; Grella, Renshaw & Wright, 2018; Davies et al ., 2022; Raza et al ., 2022; Rai, 2022).…”

“…For example, Psidium cattleianum has invaded forests in Madagascar, displacing numerous native plant species (DeSisto et al ., 2020), with cascading effects on native birds, insects, and other wildlife that depend on these plants. Some invasive plants impair soil quality and disrupt nutrient cycling (Blanco‐Canqui, 2010; Bisht & Chauhan, 2020) by emitting allelopathic compounds (Chen et al ., 2017; Weidenhamer et al ., 2023), altering nutrient availability and affecting soil microbial populations (Meena et al ., 2017; Sindhu et al ., 2017; Shahrtash, 2022; Dukare et al ., 2022). Others may disrupt the relationships between native plants and their symbiotic partners (Vanbergen et al ., 2018), such as mycorrhizal fungi (Allen et al ., 2016; Powell & Rillig, 2018).…”

Weed communities influence the dynamics of ecosystems, particularly in disturbed environments where anthropogenic activities often result in higher pollution. Understanding the dynamics existing between native weed communities and invasive species in disturbed environments is crucial for effective management and normal ecosystem functioning. Recognising the potential resistance of native weed communities to invasion in disturbed environments can help identify suitable native plants for restoration operations. This review aims to investigate the adaptations exhibited by native and non‐native weeds that may affect invasions within disturbed environments. Factors such as ecological characteristics, altered soil conditions, and adaptations of native weed communities that potentially confer a competitive advantage relative to non‐native or invasive weeds in disturbed environments are analysed. Moreover, the roles of biotic interactions such as competition, mutualistic relationships, and allelopathy in shaping the invasion resistance of native weed communities are described. Emphasis is given to the consideration of the resistance of native weeds as a key factor in invasion dynamics that provides insights for conservation and restoration efforts in disturbed environments. Additionally, this review underscores the need for further research to unravel the underlying mechanisms and to devise targeted management strategies. These strategies aim to promote the resistance of native weed communities and mitigate the negative effects of invasive weed species in disturbed environments. By delving deeper into these insights, we can gain an understanding of the ecological dynamics within disturbed ecosystems and develop valuable insights for the management of invasive species, and to restore long‐term ecosystem sustainability.

“…It is also possible that sampling root endospheres directly instead of the rhizosphere would have better let us detect host-specific signatures. However, we chose to sample the rhizosphere as that is where microbial crosstalk is likely occurring between competing microbes associated with invasive and natives (Sindhu et al, 2017) and is likely best to detect effects of competition. Regardless, our results are in line with other work showing that taxonomic beta diversity of the rhizosphere microbiome is heavily affected by drought (Ochoa-Hueso et al, 2018) and less so by plant species composition (Sayer et al, 2017), including invasion (Fahey et al, 2020).…”

Invasive plant species interact with drought to shift key functions and families in the native rhizosphere

Interactions between species invasions and climate change have the potential to drive changes in plant communities more than either factor alone. One pathway through which these effects can occur is via changes to the rhizosphere microbial community. Invasive plants can alter the taxonomic and functional makeup of these microbial communities, which may affect natives' abilities to compete with invaders. At the same time, climate change is leading to more frequent extreme wet and dry events, shifting the composition of microbial taxa available in the soil. Understanding the response of plant communities to these combined global change drivers requires a comprehensive approach that assesses the relationship between plant competition and belowground rhizosphere microbial community responses. Here we use a field experiment in a California grassland with a set of six native annual forbs (i.e., wildflowers) and three invasive annual grasses to test how competition with invasive plants alters both identity and function in the native rhizosphere microbiome, and whether competition between these groups interacts with rainfall to amplify or ameliorate these microbial shifts. Metagenomics of rhizosphere communities revealed that drought combined with competition from invaders altered a higher number of functions and families in the native rhizosphere compared to invasive competition alone or drought alone. This suggests invasion-driven shifts in the microbial community may be involved in weakening natives' ability to cope with climate change, especially drought. Understanding the role of the microbial community under invasion and climate change may be critical to mitigating the negative effects of these interacting global change drivers on native communities.
