Production of extracellular reactive oxygen species by phytoplankton: past and future directions
Julia M. Diaz,Sydney Plummer +1 more
TL;DR: Future insights into the molecular-level basis of extracellular ROS production, combined with existing high-sensitivity geochemical techniques for the direct quantification of ROS dynamics, will help unveil the ecophysiological and biogeochemical significance of phytoplankton-derived ROS in natural aquatic systems.
Production of extracellular superoxide and hydrogen peroxide by five marine species of harmful bloom-forming algae.
TL;DR: Examination of the extracellular production of the ROS superoxide and hydrogen peroxide by five marine HAB species indicates a diversity of ROS production and degradation pathways that may ultimately help illuminate the functions of HAB-derived ROS.
Extracellular superoxide production by key microbes in the global ocean
Kevin M. Sutherland,Kevin M. Sutherland,Allison Coe,Rebecca J. Gast,Sydney Plummer,Christopher Suffridge,Julia M. Diaz,Jeff S. Bowman,Scott D. Wankel,Colleen M. Hansel +9 more
TL;DR: It is demonstrated that rapid, cellnumber–dependent changes in the net superoxide production rate by Synechococcus and Pelagibacter arose primarily from changes in gross production of extracellular superoxide, not decay, suggesting thatsuperoxide production in marine waters is regulated by a diverse suite ofmarine organisms in both dark and sunlit waters.

Bioprinted Living Coral Microenvironments Mimicking Coral‐Algal Symbiosis
Daniel Wangpraseurt,Yazhi Sun,Shangting You,Sing Teng Chua,Samantha K. Noel,H. F. Willard,David B. Berry,Alexander M. Clifford,Sydney Plummer,Yi Xiang,Henry H. Hwang,Jaap A. Kaandorp,Julia M. Diaz,Todd C. La Jeunesse,Mathieu Pernice,Silvia Vignolini,Martin Tresguerres,Shaochen Chen +17 more
TL;DR: The bioprinted living coral microhabitats replicate the diffusion‐related phenomena that underlie the functioning and breakdown of the coral‐algal symbiosis and can be exploited for the additive manufacturing of synthetic designer corals.

Dynamic Regulation of Extracellular Superoxide Production by the Coccolithophore Emiliania huxleyi (CCMP 374).
TL;DR: Cell-normalized extracellular O2− production was the highest under presumably low-stress conditions during active proliferation and inversely related to cell density during exponential growth phase, suggesting a connection with photosynthetic processes.
