The power of seaweeds as plant biostimulants to boost crop production under abiotic stress

Plant, Cell &Environment, Volume 45, Issue 9, Page 2537-2553, September 2022., 2022
Abstract Abiotic stresses like drought and salinity are major factors resulting in crop yield losses and soil degradation worldwide. To meet increasing food demands, we must improve crop productivity, especially under increasing abiotic stresses due to climate change.

Characterization of an Alteromonas long-type ulvan lyase involved in the degradation of ulvan extracted from Ulva ohnoi [PDF]

Bioscience, Biotechnology, and Biochemistry, 2017
Abstract Ulvan is a sulfated polysaccharide found in the cell wall of the green algae Ulva. We first isolated several ulvan-utilizing Alteromonas sp. from the feces of small marine animals. The strain with the highest ulvan-degrading activity, KUL17, was analyzed further.

Polysaccharide degradation by the Bacteroidetes: mechanisms and nomenclature

Environmental Microbiology Reports, Volume 13, Issue 5, Page 559-581, October 2021., 2021
Summary The Bacteroidetes phylum is renowned for its ability to degrade a wide range of complex carbohydrates, a trait that has enabled its dominance in many diverse environments. The best studied species inhabit the human gut microbiome and use polysaccharide utilization loci (PULs), discrete genetic structures that encode proteins involved in the ...

Ulvan Lyases Isolated from the Flavobacteria Persicivirga ulvanivorans Are the First Members of a New Polysaccharide Lyase Family [PDF]

Journal of Biological Chemistry, 2011
Ulvans are complex sulfated polysaccharides found in the cell walls of green algae belonging to the genus Ulva. These polysaccharides are composed of disaccharide repetition moieties made up of sulfated rhamnose linked to either glucuronic acid, iduronic acid, or xylose.

New Family of Ulvan Lyases Identified in Three Isolates from the Alteromonadales Order [PDF]

Journal of Biological Chemistry, 2016
Ulvan is the main polysaccharide component of the Ulvales (green seaweed) cell wall. It is composed of disaccharide building blocks comprising 3-sulfated rhamnose linked to d-glucuronic acid (GlcUA), l-iduronic acid (IdoUA), or d-xylose (Xyl). The degradation of ulvan requires ulvan lyase, which catalyzes the endolytic cleavage of the glycoside bond ...

Glycomolecules: from "sweet immunity" to "sweet biostimulation"? [PDF]

Physiol Plant
Abstract Climate changes and environmental contaminants are daunting challenges that require an urgent change from current agricultural practices to sustainable agriculture. Biostimulants are natural solutions that adhere to the principles of organic farming and are believed to have low impacts on the environment and human health.

Seaweed polysaccharides as bio-elicitors of natural defenses in olive trees against verticillium wilt of olive

Journal of Plant Interactions, 2018
Ulvan, carrageenan, alginate and laminarin were tested in olive trees’ twigs to elicit phenolic metabolism and control verticillium wilt of olive (VWO) caused by Verticillium dahliae.

Structural And Functional Characterization Of Ulvan Degrading Polysaccharide Lyase Enzymes

The FASEB Journal, 2018
Ulvans are the sulfated cell wall polysaccharide present in marine green algae. Ulvan polysaccharides are composed mainly of 3‐sulfated rhamnose, glucuronic acid, iduronic acid and xylose. The sulfation pattern in ulvan resemble glycosaminoglycans in vertebrates.
