Article Abstract

The core mechanism of stress-resilient and growth-enhancing seed coating and pelleting technology involves applying a multifunctional protective layer to seeds with liquid or powder coating agents. This layer enhances seed resilience to environmental stressors, making the technology a promising tool for ecological restoration. We reviewed the theoretical basis and development of the technology, including seed coating principles, the selection and optimization of active and inert materials, and composite coatings, and advances in pelleting techniques. We further evaluated its effectiveness in restoring degraded grasslands, saline-alkali soils, and mining areas, highligh-ting its adaptability to diverse ecological contexts. Despite promising outcomes, challenges remain concerning the environmental sustainability, cost-effectiveness, and long-term impacts of coating materials. Future research should focus on improving material performance, establishing standardized technical frameworks, and fostering innovations that enhance environmental and economic viability. Advances in those directions would provide stronger technical support for ecological restoration.

The increasing global demand for food and the adverse environmental impacts of excessive agrochemical use highlights the urgent need for sustainable and scalable seed treatment technologies. This paper reports a novel photothermal seed coating (QC@SCCNTs) with high biocompatibility, exceptional photothermal efficiency, and notable reusability, serving as an effective alternative to conventional chemical treatments. The coating consists of sericin-functionalized carboxylated carbon nanotubes (SCCNTs) electrostatically complexed with quaternary ammonium chitosan (QC), forming a composite film (QS film).

An interactive bidirectional relationship between periodontitis and diabetes poses great challenges for the treatment of diabetic periodontitis in clinical practice. The hyperglycemic inflammatory periodontal microenvironment is characterized by oxidative damage, chronic invasive infection, excessive inflammation, unbalanced immunomodulation, progressive neuropathy, diabetic vasculopathy, and uncoupled bone resorption and formation responses. The neuromodulation strategy holds great potential to mediate and coordinate temporally the complex microenvironment for diabetic periodontal regeneration.

This study reports the design and characterization of emulsion-structured pectin-based edible films incorporating whey protein concentrate (WPC), short-chain prebiotic fibers (fructooligosaccharides, FOS; galactooligosaccharides, GOS; and xylooligosaccharides, XOS), and annatto seed oil as a source of geranylgeraniol. The formulation strategy combined citrus pectin with WPC and fibers to enhance the structural and functional properties of films while improving oil stabilization. The film-forming emulsions were processed by thermosonication to promote biopolymer dispersion and stable droplet incorporation.

Sand-trapping mechanism in psammophyte Ifloga spicata (Asteraceae).

Protoplasma

September 2025

Department of Molecular Biology, Ariel University, Ariel, Israel.

Sands are a harsh habitat with limited water and nutrients, and danger of burial or mechanical injury by moving particles. Sand entrapping plants (psammophytes) actively fix sand on their surfaces, which presumably offers adaptive benefits, such as mechanical protection and camouflage. This short article deals with the structural-functional aspects of sand-trapping in the annual psammophyte Ifloga spicata (Asteraceae).
