“…It is a nontoxic and biodegradable compound, as well as an elicitor. Therefore, it has the potential to become a new class of plant protectant, assisting towards the goal of sustainable agriculture (Bautista-Baños et al 2006). In contrast to chitin, chitosan appears to elicit activity from plant cells via charge–charge interactions with negatively charged phospholipids instead of via a receptor-specific interaction (Kauss et al 1989).…”

“…The addition of chitosan stimulated degradation of pathogens in a way resembling the application of a hyperparasite (Benhamou 2004). Recent investigations on coating showed that chitosan extends the shelf life of treated fruit and vegetables owing to its ability to form a semipermeable coating minimise the rate of respiration and reduce water loss (Bautista-Baños et al 2006). With chitosan coating, the ripening was delayed by modifying the internal atmosphere, which decreasing decays due to pathogens (El Ghaouth et al 1992, 2000).…”

Chitin is the second abundant polysaccharide in the world after cellulose. It is a vital structural component of the fungal cell wall but not for plants. In plants, fungi are recognised through the perception of conserved microbe-associated molecular patterns (MAMPs) to induce MAMP-triggered immunity (MTI). Chitin polymers and their modified form, chitosan, induce host defence responses in both monocotyledons and dicotyledons. The plants’ response to chitin, chitosan, and derived oligosaccharides depends on the acetylation degree of these compounds which indicates possible biocontrol regulation of plant immune system. There has also been a considerable amount of recent research aimed at elucidating the roles of chitin hydrolases in fungi and plants as chitinase production in plants is not considered solely as an antifungal resistance mechanism. We discuss the importance of chitin forms and chitinases in the plant–fungal interactions and their role in persistent and possible biocontrol.Abbreviations ET, ethylene; GAP, GTPase-activating protein; GEF, GDP/GTP exchange factor; JA, jasmonic acid; LysM, lysin motif; MAMP, microbe-associated molecular pattern; MTI, MAMP-triggered immunity; NBS, nucleotide-binding site; NBS-LRR, nucleotide-binding site leucine-rich repeats; PM, powdery mildew; PR, pathogenesis-related; RBOH, respiratory burst oxidase homolog; RLK, receptor-like kinase; RLP, receptor-like protein; SA, salicylic acid; TF, transcription factor.

“…COS is produced by enzymatic hydrolysis of chitosan which is the product of deacetylation of chitin. It is water-soluble, nontoxic, biocompatible, and possesses versatile functional properties (Kim and Rajapakse 2005;Bautista-Banos et al 2006). COS can elicit various defense responses, such as the synthesis of reactive species (ROS) (Lin et al 2005;Li et al 2009) and jasmonate acid (Doares et al 1995), enhancement of cell wall lignifications and production of phytoalexins, accumulation of defense-related proteinase activities (Jayaraj et al 2009;Yin et al 2010), as well as Communicated by J.

Nitric oxide production and its functional link with OIPK in tobacco defense response elicited by chitooligosaccharide

et al. 2011

Chitooligosaccharide (COS) or oligochitosan has been shown to induce tobacco defense responses which are connected with nitric oxide (NO) and OIPK (oligochitosan-induced Ser/Thr protein kinase). The aim of this study was to reveal the relationship between NO production and OIPK pathway in the defense response of tobacco elicited by COS. NO generation was investigated by epidermal strip bioassay and fluorophore microscope using fluorophore diaminofluorescein diacetate (DAF-2DA). Tobacco epidermal cells treated with COS resulted in production of NO, which was first present in chloroplast, then in nucleus, finally in the whole cell; this NO production was sensitive to NO scavenger cPTIO and the mammalian NO synthase (NOS) inhibitor L-NAME, suggesting that NOS-like enzyme maybe involved in NO generation in tobacco epidermal cells. However, NOS and nitrate reductase (NR, EC 1.6.6.1) inhibitors reduced NO content in tobacco leaves by using NO Assay Kit, suggesting both NOS and NR were involved in NO production in tobacco leaves. Using a pharmacological approach and western blotting, we provide evidence that NO acts upstream of OIPK expression. NO scavenger, NOS inhibitor partly blocked the activation of OIPK and the activities of several defense-related enzymes induced by COS; treatment with NO donor sodium nitroprusside (SNP) induced the activation of OIPK and enhanced the defense systems. The results suggest that COS is able to induce NO generation, which results in up-regulation the activities of some defense-related enzymes through an OIPK-dependent or independent pathway.

“…Moreover, it can absorb and bind water [2]. The advantages of chitosan led to numerous applications of this polymer in various branches of industry [3], medicine [4][5][6], agriculture [7][8] and environmental protection [9][10]. Chitosan usually shows good miscibility with other water-soluble polymers.…”

Analysis of Water Adsorption on Chitosan and Its Blends with Hydroxypropylcellulose

2007

Chitosan (CH) and hydroxypropylcellulose (HPC) adsorb water easily by hydrogen bonds formed with hydroxyl and amide groups present in their structures. Heat of adsorption is a thermodynamic parameter which is used to estimate the type of adsorbate molecule bond on a solid surface, among the others. Adsorption of water from vapour phase on chitosan, hydroxypropylcellulose and blends of both biopolymers in the form of films were carried out. Isotherms of water adsorption in the samples were described by the GAB equation. Correlations between mass fraction of chitosan in the sample (w f ) and the values of GAB coefficients were obtained. From parameter c in the GAB equation mean heat of adsorption of the first monomolecular layer of water molecules E 1 , and pure molar heat of adsorption q were determined.
