“…Furthermore, some of these fungi (e.g. Papiliotrema mangalensis , Sporormiella minima ) have previously been identified in mangrove plants (Kumaresan and Suryanarayanan, 2001; Hagler et al ., 2017), suggesting connectivity of fungal communities between mangroves and seagrass habitats, or a broad ecological niche. The importance of ecological connectivity between the mangrove‐seagrass‐coral reef continuum has been documented and recognized in previous studies (Berkström et al ., 2013; Du et al ., 2020), but research examining the fungal communities in the marine microbiome is sorely lacking (Trevathan‐Tackett et al ., 2019).…”

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.

“…Aquatic habitats are extremely diverse in size and physiochemical properties and may well harbor the largest pool of yeast cells (17). Wetlands and phytotelmata, containing high levels of organic materials, enable large autochthonous yeast populations (51). An increasing number of studies demonstrate the large number of yeast species adapted to diverse aquatic environments (Figure 1), such as seawater [e.g., genus Yamadazyma (15)], deep-sea hydrothermal vents (33), environments associated with macro-and microalgae (36), hypersaline water (42,49), and glacial and subglacial environments of polar regions and similar habitats (18,100,131).…”

Since the emergence of the first fungi some 700 million years ago, unicellular yeast-like forms have emerged multiple times in independent lineages via convergent evolution. While tens to hundreds of millions of years separate the independent evolution of these unicellular organisms, they share remarkable phenotypic and metabolic similarities, and all have streamlined genomes. Yeasts occur in every aquatic environment yet examined. Many species are aquatic; perhaps most are amphibious. How these species have evolved to thrive in aquatic habitats is fundamental to understanding functions and evolutionary mechanisms in this unique group of fungi. Here we review the state of knowledge of the physiological and ecological diversity of amphibious yeasts and their key evolutionary adaptations enabling survival in aquatic habitats. We emphasize some genera previously thought to be exclusively terrestrial. Finally, we discuss the ability of many yeasts to survive in extreme habitats and how this might lend insight into ecological plasticity, including amphibious lifestyles. Expected final online publication date for the Annual Review of Microbiology, Volume 75 is October 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
