Comparative Study of Sulfated Polysaccharides From Ulva Lactuca Grown in Tunisia and Morocco: in Vitro Antioxidant Activity and in Vivo Anti‐Inflammatory and Anti‐Ulcer Effects

open access: yesChemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT This study presents a comparative analysis of sulfated polysaccharides extracted from Ulva lactuca collected in Tunisia (PSUT) and Morocco (PSUM). FTIR confirmed the presence of sulfate groups, while GC‐MS identified diverse sugar components. Both polysaccharides showed strong antioxidant activity, with DPPH and ABTS radical scavenging rates ...

Presence of Exogenous Sulfate Is Mandatory for Tip Growth in the Brown Alga Ectocarpus subulatus

open access: yesFrontiers in Plant Science, 2020
Brown algae (Phaeophyceae) are multicellular photoautrophic organisms and the largest biomass producers in coastal regions. A variety of observations indicate that their extracellular matrix (ECM) is involved with screening of salts, development, cell ...

Algal glycans promote microbial turnover of organic matter through stabilization of subtidal permeable sandy sediments

open access: yesLimnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Permeable sands on continental shelves host microbial communities that drive organic carbon turnover, oxygen fluxes and nitrogen loss. Advective porewater flow associated with sedimentary bedforms maintains these rates and fluxes. Modeling and laboratory studies suggest that advective porewater flow is tightly coupled to bedform stability ...

Recent Progressions in Applications of Bioactive Polysaccharides in Food and Health Sciences: A Comprehensive Review

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Polysaccharides play a pivotal role in the development of safe and healthy foods. They ameliorate fatigue, preserve the microflora of the gastrointestinal tract, and provide health for the gut in living organisms. These biopolymers are applied for the fabrication of breakthrough drug delivery systems and potential platforms in regenerative medicine ...

The optimization of crop response to climatic stress through modulation of plant stress response mechanisms. Opportunities for biostimulants and plant hormones to meet climate challenges.

open access: yesNew Phytologist, Volume 249, Issue 1, Page 130-151, January 2026.
Summary This review discusses the use of agronomic management practices to enhance crop stress resilience to climate stress through the modulation of natural plant growth regulatory pathways. The use of biostimulants or plant hormones to improve crop resilience is subject to strict regulatory oversight if changes in the regulation of plant growth are ...
