A Fusarium sacchari Glycoside Hydrolase 12 Protein FsEG1 Is a Major Virulence Factor During Sugarcane Infection and Confers Resistance to Pokkah Boeng Disease via the HIGS Strategy

Plant Biotechnology Journal, EarlyView.
ABSTRACT Pokkah Boeng disease (PBD), caused by Fusarium sacchari, has severely impacted the yield and quality of sugarcane, resulting in significant economic losses. However, the molecular interaction mechanisms between F. sacchari and sugarcane remain poorly understood.

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

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 ...

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.

Characterisation of High Alkaline-Tolerant Novel Ulvan Lyase from Pseudoalteromonas agarivorans: Potential Applications of Enzyme Derived Oligo-Ulvan as Anti-Diabetic Agent

Marine Drugs
Green algae, particularly Ulva species, are rich in complex polysaccharides, such as ulvan, which have significant potential for biotechnological applications. However, the biochemical properties of ulvan depolymerised products remain underexplored.

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.).

Unraveling the molecular mechanism of polysaccharide lyases for efficient alginate degradation

Nature Communications
Alginate lyases (ALs) are essential for breaking down brown macroalgae alginates, widely used naturally-occurring polysaccharides. Their molecular mechanisms remain challenging due to the lack of catalytically competent Michaelis-Menten complex structures.
