“…It can do so through enhancing or suppressing germination, have positive or negative feedback systems, engage in symbiotic interactions or alternatively influence soil nutrient cycles and soil enzyme concentrations [139][140][141]. Numerous hypotheses have been put forward to explain or understand the role of microorganisms in the success of invasive plant species [141,142] (Table 1). However, very little research has been undertaken on the role of microorganisms on the success of invasive plants into the fynbos biome.…”

Microbial Communities in the Fynbos Region of South Africa: What Happens during Woody Alien Plant Invasions

The Cape Floristic Region (CFR) is globally known for its plant biodiversity, and its flora is commonly referred to as fynbos. At the same time, this area is under severe pressure from urbanization, agricultural expansion and the threat of invasive alien plants. Acacia, Eucalyptus and Pinus are the common invasive alien plants found across the biome and considerable time, effort and resources are put into the removal of invasive alien plants and the rehabilitation of native vegetation. Several studies have shown that invasion not only affects the composition of plant species, but also has a profound effect on the soil chemistry and microbial populations. Over the last few years, a number of studies have shown that the microbial populations of the CFR are unique to the area, and harbour many endemic species. The extent of the role they play in the invasion process is, however, still unclear. This review aims to provide an insight into the current knowledge on the different microbial populations from this system, and speculate what their role might be during invasion. More importantly, it places a spotlight on the lack of information about this process.

“…Soil microbes play an important role in alien plant invasion. Invasive plants can modify native soil microbial community; in turn, changes in soil microbes can result in a positive or negative effect on the competition between native and invasive plants (Ravichandran & Thangavelu, 2017). Therefore, considering these effects is beneficial to predict the invasion mechanism.…”

The exotic plant Spartina alterniflora is expanding rapidly along China's coast regions, seriously threatening native ecosystems. Soil bacteria are important for biogeochemical cycles, including those of carbon, nitrogen, and sulfur, in wetland ecosystems. There is growing evidence that microorganisms are important in case of plant invasion. In the present study, we studied the interlacing area of S. alterniflora and Suaeda heteroptera, selected soil of invaded and non‐invaded regions and explored the effect of the composition and diversity of bacterial communities in coastal wetlands. The bacterial community composition of invasive and noninvasive areas was subjected to high‐throughput sequencing. In the five areas tested, the main bacterial phyla were Proteobacteria, Bacteroides, and Acidobacteria; the richness of the bacterial community in the soil increased after S. alterniflora invasion, most changes occurred at the genus level. The relative abundances of Desulfobulbus and Sulfurovum were higher in invasive areas than in noninvaded areas. PCA, RDA, and LEfSe analyses found that the S. alterniflora invasion significantly influenced the bacterial community and physicochemical properties of wetland soil. In conclusion, soil microbial community composition was tightly associated with S. alterniflora invasion. This study provide an important scientific basis for further research on the invasion mechanism of S. alterniflora.

“…Plant-microbe associations occur on a small scale, but can impact global patterns, including plant and microbial biodiversity (Cui and He 2009; Ravichandran and Thangavelu 2017; Kandlikar et al 2019). Plants associate with distinct microbial communities that can benefit plants by enhancing nutrient acquisition (Emami et al 2018; Fei et al 2020) and protection against pathogens (De Curtis et al 2010; Akhtar et al 2011).…”

Serpentine soils are drought-prone and rich in heavy metals, and plants growing on serpentine soils host distinct microbial communities that may affect plant survival and phenotype. However, whether the rhizosphere communities of plants from different soil chemistries are initially distinct or diverge over time may help us understand drivers of microbial community structure and function in stressful soils. Here, we test the hypothesis that rhizosphere microbial communities will converge over time (plant development), independent of soil chemistry and microbial source. We grew Plantago erecta in serpentine or nonserpentine soil, with serpentine or nonserpentine microbes and tracked plant growth and root phenotypes. We used 16S rRNA barcoding to compare bacterial species composition at seedling, vegetative, early-, and late-flowering phases. Plant phenotype and rhizosphere bacterial communities were mainly structured by soil type, with minor contributions by plant development, microbe source and their interactions. Serpentine microorganisms promoted early flowering in plants on non-serpentine soils. Despite strong effects of soil chemistry, the convergence in bacterial community composition across development demonstrates the importance of the plant-microbe interactions in shaping microbial assembly processes across soil types.
