Description

Seagrasses are one of the most efficient natural sinks of carbon dioxide (CO2) on Earth. Despite covering less than 0.1% of coastal regions, they have the capacity to bury up to 10% of marine organic matter and can bury the same amount of carbon 35 times faster than tropical rainforests. On land, the soil’s ability to sequestrate carbon is intimately linked to microbial metabolism. Despite the growing attention to the link between plant production, microbial communities, and the carbon cycle in terrestrial ecosystems, these processes remain enigmatic in the sea. Here, we show that seagrasses excrete organic sugars, namely in the form of sucrose, into their rhizospheres. Surprisingly, the microbial communities living underneath meadows do not fully use this sugar stock in their metabolism. Instead, sucrose piles up in the sediments to mM concentrations underneath multiple types of seagrass meadows. Sediment incubation experiments show that microbial communities living underneath a meadow use sucrose at low metabolic rates. Our metagenomic analyses revealed that the distinct community of microorganisms occurring underneath meadows is limited in their ability to degrade simple sugars, which allows these compounds to persist in the environment over relatively long periods of time. Our findings reveal how seagrasses form blue carbon stocks despite the relatively small area they occupy. Unfortunately, anthropogenic disturbances are threatening the long-term persistence of seagrass meadows. Given that these sediments contain a large stock of sugars that heterotopic bacteria can degrade, it is even more important to protect these ecosystems from degradation.

Description


(R)-prunasin is a prunasin. Prunasin is a natural product found in Polypodium californicum, Chaenorhinum minus, and other organisms with data available. Prunasin is found in almond. Prunasin is isolated from kernels of Prunus species, immature fruits of Passiflora species and leaves of perilla (Perilla frutescens var. acuta) Prunasin belongs to the family of O-glycosyl Compounds. These are glycosides in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Isolated from kernels of Prunus subspecies, immature fruits of Passiflora subspecies and leaves of perilla (Perilla frutescens variety acuta). Prunasin is found in many foods, some of which are almond, sour cherry, black elderberry, and herbs and spices. Prunasin is found in almond.
