“…Consistent with other work examining microbial community structure in a variety of host taxa, we show that microbial community structure does exist around the Malay Peninsula [39, 40, 54, 55, 78, 79], and this structure is driven primarily by plant part sampled, location sampled, and host identity. It is likely that these differences are driven by local environmental conditions, with locations closer together tending to have more similar environmental conditions in comparison to those that are more geographical distant.…”

“…The genus Marinomonas (here, enriched in all living plant tissues) is abundant in marine ecosystems where it is implicated in melanin synthesis and the catabolism of dimethylsulfoniopropionate (DMSP) to dimethyl sulfide (DMS). DMSP metabolisers are acknowledged as important constituents of the coral microbiome where they have principal roles in sulphur cycling, pathogen suppression and mediating thermal stress responses [78,[97][98][99]. The same properties that make DMSP metabolisers beneficial microorganisms in coral mean that this group warrants further investigation in mangroves, particularly as they are enriched in both species.…”

Microbes have fundamental roles underpinning the functioning of our planet, they are involved in global carbon and nutrient cycling, and support the existence of multicellular life. The mangrove ecosystem is nutrient limited and without microbial cycling, life in this harsh environment would likely not exist. The mangroves of Southeast Asia are the oldest and most biodiverse of all the planets. They have vital roles helping to prevent shoreline erosion, act as nursery grounds for many marine species and contain significant stocks of sequestered carbon. Despite these recognised benefits and the importance of microbes in these ecosystems, studies examining the mangrove microbiome are scarce, especially in the Southeast Asian biodiversity hotspot. Here we examine the microbiome of Avicenia alba and Sonneratia alba and identify a core microbiome of 81 taxa, a further eight taxa (Pleurocapsa, Tunicatimonas, Halomonas, Marinomonas, Rubrivirga, Altererythrobacte, Lewinella, and Erythrobacter) were found to be differentially abundant suggesting key roles in this microbiome, with the identified dimethylsulfoniopropionate (DMSP) metabolisers having important functions in these habitats. The majority of those identified are involved in nutrient cycling or involved in the production of compounds that promote host survival. Increasingly, blue carbon and nature-based solutions to climate change are heralded as viable mitigation steps to limit climate change, however, this is done with little to no consideration of the microbial communities that cycle sequestered carbon in these environments. Here, we examine the microbial communities present in sediment samples taken in close proximity to each tree, sediment samples represent a major sink of atmospheric carbon and understanding how the associated communities will change as climate change advances will become an increasingly important part of carbon stock assessments. Knowing what microbes are presently there is an important first step in this process.

“…Previous studies have suggested that both host taxa and geolocation could become the driving forces of coral microbial community structure. However, it presented different conclusions according to the individual studies, even contradictorily ( Damjanovic et al, 2020 ; Kanisan et al, 2022 ). Recently, it was revealed that microbial community dissimilarity increased with geographical distances of less than 30 kilometers, but the coral host taxon still played a leading role ( Dunphy et al, 2019 ).…”

“…Later, host identity was proven to play a dominant role in structuring the microbiome of Caribbean corals, while microbial community dissimilarity increased with geographical distance ( Dunphy et al, 2019 ). Recently, the coral host was also reported as the main driver for structural differences in microbial communities in reef corals of the Malay Peninsula ( Kanisan et al, 2022 ). In addition, a study on Pocillopora verrucosa and Turbinaria peltata , endemic corals in the South China Sea, showed that both host and geographical factors affect coral microbial communities ( Chen et al, 2021 ).…”

Coral-associated microbial communities play a vital role in underpinning the health and resilience of reef ecosystems. Previous studies have demonstrated that the microbial communities of corals are affected by multiple factors, mainly focusing on host species and geolocation. However, up-to-date, insight into how the coral microbiota is structured by vast geographic distance with rich taxa is deficient. In the present study, the coral microbiota in six stony coral species collected from the coastal area of three countries, including United States of America (USA), Australia and Fiji, was used for analysis. It was found that the geographic influence on the coral microbiota was stronger than the coral host influence, even though both were significant. Interestingly, the contribution of the deterministic process to bacterial community composition increased as geographical distance grew. A total of 65 differentially abundant features of functions in coral microbial communities were identified to be associated with three geolocations. While in the same coastal area of USA, the similar relationship of coral microbiota was consistent with the phylogenetic relationship of coral hosts. In contrast to the phylum Proteobacteria, which was most abundant in other coral species in USA, Cyanobacteria was the most abundant phylum in Orbicella faveolata. The above findings may help to better understand the multiple natural driving forces shaping the coral microbial community to contribute to defining the healthy baseline of the coral microbiome.

“…Based on their thermal sensitivity, these genera have the potential as biomarkers of high temperature in coral ecosystems ( 58 ). Meanwhile, shifts in coral-associated bacterial communities may contribute more to the resilience and survival of coral holobionts to environmental disturbances ( 59 , 60 ). The beneficial or probiotic bacteria of corals, such as Erythrobacter , Endozoicomonas , and Ruegeria , occupied a relatively higher proportion in bleached coral and seem to be a defensive mechanism, whereas pathogens (for example, Vibrio ) were significantly increased in the bleached G .…”
