“…In order to increase leaf greenness and sugar status, seedlings may need to be provided with critical nutrients (Wingler et al, 2006;Engels et al, 2012). Ncarboxymethyl Chitosan applied to maize increased the amount of N and N protein as well as the activity of vital N metabolic enzymes (Sajid et al, 2020;Boamah et al, 2023). The nutrient nitrogen is well-known for being necessary for the synthesis of numerous enzymes, cytokinin, and chlorophyll.…”

Chitosan is a natural polysaccharide that is commonly made by chitin deacetylation, which is the structural component in sea crustaceans. It is beneficial to plant growth and development. Its use to improve chilli pepper production had been shown to elevate environmental and health issues. Hence, different concentrations of Chitosan and application methods on growth and yield characteristics of chilli pepper were investigated. Three replications were used in the split plot design experiment. Chitosan application types (foliar and media) were assigned to the main plots while Chitosan concentration levels were assigned to the sub plots. Apart from number of functional leaves and chlorophyll content that had significant one-way interaction of Chitosan application method (p < 0.05), all other growth and yield parameters were not significant (p > 0.05) for both sole and interactions. Highest number of functional leaves and chlorophyll content occurred under foliar application of Chitosan. Greater plant height and stem diameter was achieved under the media application of Chitosan with a rate of 50 ppm and 100 ppm respectively at 6 weeks after planting. Foliar application of Chitosan as a sole factor improved all the yield attributes of chilli pepper.

“…Collectively when considering degraded polysaccharides, it can be concluded that VEPS exhibited greater efficacy in enhancing spinach growth than MEPS did. Related studies have shown that the crystal structure of polysaccharides plays a crucial role in promoting plant growth and increasing the soluble protein content [66]. Because MEPS lacks this crystal structure, this may explain why VEPS has greater biological activity [67].…”

This study presents a comparison between two hydrolysis systems (MnO2/H2O2 and ascorbic acid (VC)/H2O2) for the depolymerization of exopolysaccharide (EPS) from Lactobacillus plantarum LPC-1. Response surface methodology (RSM) was used to optimize these two degradation systems, resulting in two H2O2-free degradation products, MEPS (MnO2/H2O2-treated EPS) and VEPS (VC/H2O2-treated EPS), where H2O2 residues in the final products and their antioxidant activity were considered vital points. The relationship between the structural variations of two degraded polysaccharides and their antioxidant activity was characterized. Physicochemical tests showed that H2O2 had a notable impact on determining the total and reducing sugars in the polysaccharides, and both degradation systems efficiently eliminated this effect. After optimization, the average molecular weight of EPS was reduced from 265.75 kDa to 135.41 kDa (MEPS) and 113.11 kDa (VEPS), improving its antioxidant properties. Characterization results showed that the two hydrolysis products had similar major functional groups and monosaccharide composition as EPS. The crystal structure, main chain length, and branched chain number were crucial factors affecting the biological activity of polysaccharides. In pot testing, two degraded polysaccharides improved spinach quality more than EPS due to their lower molecular weights, suggesting the advantages of low-molecularweight polysaccharides. In summary, these two degradation techniques offer valuable insights for further expanding the utilization of microbial resources.

“…The underground plant parasitic nematodes attack various crops’ root systems, causing root galls, stunted growth, and increased susceptibility to pathogen attack and abiotic stress ( Yan and Xie, 2015 ). Accumulating body of evidence has shown that exogenous application of chitosan triggers plant defence-related pathways in various crops, such as potato, tomato ( Vasyukova et al., 2001 ; Fan et al., 2020 ; Boamah et al., 2023 ), barley, banana ( Maciá-Vicente et al., 2009 ; Suarez-Fernandez et al., 2021 ), and soybean ( Mwaheb et al., 2017 ). Consistently, chitosan also promotes host resistance to Meloidogyne spp.…”

Chitosan-induced biotic stress tolerance and crosstalk with phytohormones, antioxidants, and other signalling molecules

Several polysaccharides augment plant growth and productivity and galvanise defence against pathogens. Such elicitors have ecological superiority over traditional growth regulators, considering their amplified biocompatibility, biodegradability, bioactivity, non-toxicity, ubiquity, and inexpensiveness. Chitosan is a chitin-derived polysaccharide that has recently been spotlighted among plant scientists. Chitosan supports plant growth and development and protects against microbial entities such as fungi, bacteria, viruses, nematodes, and insects. In this review, we discuss the current knowledge of chitosan’s antimicrobial and insecticidal potential with recent updates. These effects are further explored with the possibilities of chitosan’s active correspondence with phytohormones such as jasmonic acid (JA), salicylic acid (SA), indole acetic acid (IAA), abscisic acid (ABA), and gibberellic acid (GA). The stress-induced redox shift in cellular organelles could be substantiated by the intricate participation of chitosan with reactive oxygen species (ROS) and antioxidant metabolism, including hydrogen peroxide (H2O2), superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD). Furthermore, we propose how chitosan could be intertwined with cellular signalling through Ca2+, ROS, nitric oxide (NO), transcription factors (TFs), and defensive gene activation.
