Bacteria associated with the Symbiodiniaceae's phycosphere.

Symbiotic interactions between Symbiodiniaceae and bacteria are still poorly explored, especially those . Here, we adapted a technique that allows for the enrichment of intact and metabolically active Symbiodiniaceae cells (SC) and their associated bacteria from the tissue of the model coral , using a discontinuous gradient of solution of isotonic Percoll (SIP). The SC were concentrated in the 50% SIP fraction, as determined by microscopy.

Mevalonosomes: specific vacuoles containing the mevalonate pathway in Plocamium brasiliense cortical cells (Rhodophyta).

This paper has identified, for the first time in a member of the Rhodophyta, a vacuolar organelle containing enzymes that are involved in the mevalonate pathway-an important step in red algal isoprenoid biosynthesis. These organelles were named mevalonosomes (Mev) and were found in the cortical cells (CC) of Plocamium brasiliense, a marine macroalgae that synthesizes several halogenated monoterpenes. P.

New Insights on the terpenome of the red seaweed Laurencia dendroidea (Florideophyceae, Rhodophyta).

The red seaweeds belonging to the genus Laurencia are well known as halogenated secondary metabolites producers, mainly terpenoids and acetogennins. Several of these chemicals exhibit important ecological roles and biotechnological applications. However, knowledge regarding the genes involved in the biosynthesis of these compounds is still very limited.
