Carbon and nitrogen contents depends on macroalgal species, their tissue section, and development stage

Phycological Research, EarlyView.
SUMMARY Assessing the potential for macroalgae to function as a carbon sink (blue carbon) and nitrogen (N) assimilation is under intensive investigation. The content of elemental carbon (C) and N in macroalgae is the best indicator of their potential; however, with respect to the thallus, C and N content varies in space and time.

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

Biostimulatory Potential of Sargassum muticum Extracts in Enhancing Sesame Tolerance to Water Deficit During Germination and Seedling Growth

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Water deficit is a major abiotic stress that limits plant growth and productivity. This article evaluates the effectiveness of an aqueous seaweed extract (ASE) from Sargassum muticum as an ecofriendly biostimulant to alleviate water deficit stress during seed germination and early seedling growth of sesame (Sesamum indicum L.).
