Chitosan is a biodegradable and biocompatible natural polymer that has been extensively explored in recent decades. The Food and Drug Administration has approved chitosan for wound treatment and nutritional use. Furthermore, chitosan has paved the way for advancements in different biomedical applications including as a nanocarrier and tissue-engineering scaffold. Its antibacterial, antioxidant, and haemostatic properties make it an excellent option for wound dressings. Because of its hydrophilic nature, chitosan is an ideal starting material for biocompatible and biodegradable hydrogels. To suit specific application demands, chitosan can be combined with fillers, such as hydroxyapatite, to modify the mechanical characteristics of pH-sensitive hydrogels. Furthermore, the cationic characteristics of chitosan have made it a popular choice for gene delivery and cancer therapy. Thus, the use of chitosan nanoparticles in developing novel drug delivery systems has received special attention. This review aims to provide an overview of chitosan-based nanoparticles, focusing on their versatile properties and different applications in biomedical sciences and engineering.

“…PAL enzyme activity in the leaves of resistant cultivars of barley genotypes increased against Bipolaris sorokiniana infection. The fungal infection Fusarium oxysforum f. sp cube (FOC) against male bananas causes increase in PAL enzyme activity (Kumar et al 2022). Phenolic compounds associated with PAL enzymes increase as an initial response to plant resistance when plants are subjected to biotic and abiotic defense assays (Oliva et al 2020).…”

Abstract. Solekha R, Puspaningrum NNT, Ramadani AH, Hapsari FD, Ermavitalini D, Purnobasuki H. 2024. Effect of Curvularia andropogonis infection on secretory tissues and phenylalanine ammonia lyase enzyme of Cymbopogon nardus. Biodiversitas 25: 598-604. Cymbopogon nardus L. oil production decreased due to red spot disease caused by Curvularia andropogonis fungal infection. The objective of this study was to investigate the infection effect of C. andropogonis on secretory tissue formation in citronella leaf epidermis and the enzymatic defense expression response in C. nardus. Anatomical responses were observed from leaf secretory structure slide while PAL reactions were measured from enzyme activity in leaf samples of three treatment groups with healthy, wounded, and infected conditions. The morphological results of infected leaves changed from green to brownish triggered by pathogenic infection conditions that activated the PAL enzyme pathway and phenylpropanoid production as a defense. The results showed that the density of cells storing secondary metabolites flavonoids, tannins, and saponins in infected leaves increased compared to wounded and healthy ones. Secondary metabolites flavonoids, tannins, and saponins in wounded leaves increased compared to healthy leaves. It was observed that enzymatic response escalated when infection occurred. PAL enzyme activity test of C. nardus leaves showed that infected leaves had the highest value (0.0051 U/mL), followed by wounded leaves (0.0033 U/mL) and healthy leaves (0.0027 U/mL). Likewise, the specific activity of PAL enzyme in infected leaves was highest (0.121 U/mg), followed by injured leaves (0.040 U/mg) and healthy leaves (0.022 U/mg). The overall results exhibited that C. andropogonis infection affects the quality of secretory tissue and increases PAL enzyme activity as a form of defense. By detecting secretory tissue and defense enzymes after infection, further research can be carried out regarding controlling Curvularia andropogonis infections by engineering enzymes and secondary metabolites.

Agriculture plays a fundamental role in ensuring global food security, yet plant diseases remain a significant threat to crop production. Traditional methods to manage plant diseases have been extensively used, but they face significant drawbacks, such as environmental pollution, health risks and pathogen resistance. Similarly, biopesticides are eco-friendly, but are limited by their specificity and stability issues. This has led to the exploration of novel biotechnological approaches, such as the development of synthetic proteins, which aim to mitigate these drawbacks by offering more targeted and sustainable solutions. Similarly, recent advances in genome editing techniques—such as meganucleases (MegNs), zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR)—are precise approaches in disease management, but are limited by technical challenges and regulatory concerns. In this realm, nanotechnology has emerged as a promising frontier that offers novel solutions for plant disease management. This review examines the role of nanoparticles (NPs), including organic NPs, inorganic NPs, polymeric NPs and carbon NPs, in enhancing disease resistance and improving pesticide delivery, and gives an overview of the current state of nanotechnology in managing plant diseases, including its advantages, practical applications and obstacles that must be overcome to fully harness its potential. By understanding these aspects, we can better appreciate the transformative impact of nanotechnology on modern agriculture and can develop sustainable and effective strategies to mitigate plant diseases, ensuring enhanced agricultural productivity.
