311.1747	[M+H]+ PPM:6.4	Posidonia oceanica	root	MALDI (CHCA)	20190614_MS1_A19r-20 - MTBLS1746 Resolution: 17μm, 262x276 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.

Sugar phosphate, also known as sinapoylcholine or sinapine, belongs to coumaric acids and derivatives class of compounds. Those are aromatic compounds containing Aromatic compounds containing a cinnamic acid moiety (or a derivative thereof) hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. Sugar phosphate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Sugar phosphate can be found in a number of food items such as common sage, tea leaf willow, broccoli, and sweet bay, which makes sugar phosphate a potential biomarker for the consumption of these food products. Sugar phosphate exists in all living organisms, ranging from bacteria to humans. Sinapine (CAS: 18696-26-9), also known as sinapoylcholine, belongs to the class of organic compounds known as morphinans. These are polycyclic compounds with a four-ring skeleton with three condensed six-member rings forming a partially hydrogenated phenanthrene moiety, one of which is aromatic while the two others are alicyclic. Sinapine is an extremely weak basic (essentially neutral) compound (based on its pKa). Sinapine has been detected, but not quantified, in garden cress and horseradish. Sinapine is found in brassicas. It is a storage protein isolated from the seeds of Brassica napus (rape). This could make sinapine a potential biomarker for the consumption of these foods. Sinapine is an acylcholine in which the acyl group specified is sinapoyl. It has a role as a photosynthetic electron-transport chain inhibitor, an antioxidant and a plant metabolite. It is functionally related to a trans-sinapic acid. Sinapine is a natural product found in Alliaria petiolata, Isatis quadrialata, and other organisms with data available.
