“…Nevertheless, oxides were precipitated in the phytodebris layers, and had a major control on the content of elements, as evidenced below (Table 4). The anomalous degree of oxidation in the carbonaceous phytodebris, rather than sulfide formation, is consistent with modern mycorrhizal fungi in symbiosis with local vegetation which are capable of sulfide oxidation/dissolution and bioaccumulation of metals (Cecchi et al, 2019).…”

The Rhynie Chert (Figure 1) is a Lower Devonian (∼407 Ma) lagerstätte of early plants and their accompanying biota (Strullu-Derrien et al., 2014;Trewin & Fayers, 2015), preserved by early silicification from adjacent hot spring activity (Baron et al., 2004). The deposit constitutes the world's oldest preserved terrestrial ecosystem, including extensive evidence for the colonization of plants by mycorrhizal fungi (Harper et al., 2020;Krings et al., 2018;Strullu-Derrien et al., 2014;Taylor et al., 2004). Arbuscular mycorrhizal fungi evolved in symbiosis with early plants which were colonizing the Devonian land surface (Remy et al., 1994). The plants require trace elements, supplied by the fungi, while the fungi gain carbon from the photosynthesizing plant. Fungi similarly controlled nutrients that were required by animals in the Rhynie ecosystem (Strullu-Derrien et al., 2016). Fungi also contribute to plant resistance against contaminating trace elements (Colpaert et al., 2011;Hildebrandt et al., 2007;Neidhardt, 2020). It is important to note that much current work on the fungal response to metals relates to ectomycorrhizal or ericoid mycorrhizal fungi, which had not evolved at the time of Rhynie Chert deposition. This includes numerous studies on the fungus Aspergillus. However, there is also evidence that arbuscular mycorrhizae, which were present at Rhynie, influence the occurrence and speciation of numerous trace elements,

“…Most plants are not able to mitigate the impacts of environmental stress, depending on microorganisms (mainly fungi and bacteria) (Singh and Shourie, 2021 ). Beneficial fungal symbioses (mycorrhization and endophytism) not only can allow plants specific habitats colonization, but also the adaptation to many stresses due to the global climatic change (e.g., increase of carbon dioxide [CO 2 ], UV radiation, and desertification, among others) (Rodriguez and Redman, 2008 ; Rodriguez et al, 2008 ; Choudhary, 2012 ; Cecchi et al, 2019b ; Singh and Shourie, 2021 ). Together with fungi, bacteria are also known to be plant growth promoters (Basu et al, 2021 ).…”

The co-growth and synergistic interactions among fungi and bacteria from the rhizosphere of plants able to hyper accumulate potentially toxic metals (PTMs) are largely unexplored. Fungi and bacteria contribute in an essential way to soil biogeochemical cycles mediating the nutrition, growth development, and health of associated plants at the rhizosphere level. Microbial consortia improve the formation of soil aggregates and soil fertility, producing organic acids and siderophores that increase solubility, mobilization, and consequently the accumulation of nutrients and metals from the rhizosphere. These microorganism consortia can both mitigate the soil conditions promoting plant colonization and increase the performance of hyperaccumulator plants. Indeed, microfungi and bacteria from metalliferous soils or contaminated matrices are commonly metal-tolerant and can play a key role for plants in the phytoextraction or phytostabilization of metals. However, few works deepen the effects of the inoculation of microfungal and bacterial consortia in the rhizosphere of metallophytes and their synergistic activity. This mini-review aimed to collect and report the data regarding the role of microbial consortia and their potentialities known to date. Moreover, our new data had shown an active fungal-bacteria consortium in the rhizosphere of the hyperaccumulator plant Alyssoides utriculata.
