A marine … Web25 apr. 2014 · They found cell clusters within known ecotypes that indicated that the relative abundance of cyanobacterial subpopulations shifted along with the seasons, likely in response to environmental changes. They then analyzed the cells on a finer scale, sequencing partial genomes from select clusters.

WebSynechococcus (from the Greek synechos, in succession, and the Greek kokkos, granule) is a unicellular cyanobacterium that is very widespread in the marine environment.Its size varies from 0.8 to 1.5 µm.The photosynthetic coccoid cells are preferentially found in well–lit surface waters where it can be very abundant (generally 1,000 to 200,000 cells per ml). Web23 jan. 2024 · Synechococcus was discovered first because of its intense orange phycoerythrin fluorescence. Prochlorococcus wasn't discovered until the 1980s when researchers wee able to detect the dim red fluorescence emitted by its unique divinyl derivatives of chlorophyll a and b. fisher lds
