“…While the pathogenic effects of R. microporus in seagrasses remain undocumented, long‐term studies on the Merambong Shoal population may yield insights into the effects of R. microporus on the health of seagrass meadows and how it enters the marine environment. The characterization of fungal communities can provide insights into host health, fungal symbiotic relationships and the suitability of hosts for transplantation into new environments (Zahn and Amend, 2017; Lee et al ., 2019; Wainwright et al ., 2019b; Lee et al ., 2020; Egan et al ., 2021). Furthermore, some of these fungi (e.g.…”

Distributed across both the tropical Atlantic and Pacific oceans, the seagrass Halophilia ovalis stabilizes coastal sediment, thereby preventing shoreline erosion and is also an important food source for megaherbivores such as dugongs. However, seagrass meadows globally are under severe duress due to both climate change and anthropogenic activities. We characterized the mycobiome of Halophilia ovalis at seven sites in the Malay Peninsula using ITS1 rDNA amplicon sequences and investigated differences in fungal community structure. We found that geographic location was a significant factor shaping fungal communities and that marine sediment harboured significantly higher diversity when compared to H. ovalis leaves, roots and rhizomes. Taken together, it is likely that locality rather than specific plant structure determines fungal community structure in H. ovalis. Because the plant mycobiome is known to exert a strong effect on plant health, to maximize the success of future seagrass transplantation and restoration work we propose that these efforts consider the importance of seagrass mycobiomes at all stages.

“…Introduction of native soil-derived arbuscular mycorrhizal fungi accelerates regeneration of species-rich vegetation in previously barren post-mining landscapes in Estonia 67 . Hawaiian fungal reintroduction efforts have enhanced native plant recovery and disease resistance 68 . Recent restoration work in high-latitude grasslands could only achieve aboveground plant diversity similar to native systems when soil from those same native systems was also introduced at the time of seeding 69 .…”

Our community has demonstrated that microbiome manipulation can create positive outcomes for biodiversity and ecosystem health, with notable examples coming from restoration ecology 64,68,69 and mycorrhiza in forestry 119 . In many ways, we already know that microbiome management for ecosystem services is both possible and can be massively beneficial 120 .…”
