“…The defense responses relying on this pathway include chitinase and glucanase activities that have been shown to be induced by chitosan in Citrus and Fragaria species [112,113], lipoxygenase [114,115] and the accumulation of phytoalexins [49,79,116]. …”

Chitin and chitosan are naturally-occurring compounds that have potential in agriculture with regard to controlling plant diseases. These molecules were shown to display toxicity and inhibit fungal growth and development. They were reported to be active against viruses, bacteria and other pests. Fragments from chitin and chitosan are known to have eliciting activities leading to a variety of defense responses in host plants in response to microbial infections, including the accumulation of phytoalexins, pathogen-related (PR) proteins and proteinase inhibitors, lignin synthesis, and callose formation. Based on these and other proprieties that help strengthen host plant defenses, interest has been growing in using them in agricultural systems to reduce the negative impact of diseases on yield and quality of crops. This review recapitulates the properties and uses of chitin, chitosan, and their derivatives, and will focus on their applications and mechanisms of action during plant-pathogen interactions.

“…These enzymatic activities are expressed as enzymatic units per gram fresh weight (U/GMF). The phenol extraction is performed according to the protocol described by El Hadrami et al (1997). The content of phenolic compounds was determined according to their oxidation by the Folin-Ciocalteu reagent.…”

“…The main disease control method currently available is the multiplication and use of tolerant/resistant cultivars. Such tolerance/resistance has been reported to be due to the activation of peroxidases (Baaziz, 1989), glucanases and chitinases (Amraoui, 1993), as well as to the accumulation of phenolics (Ziouti et al, 1996; El Hadrami et al, 1997), among which a crucial role has been attributed to hydroxycinnamic acid derivatives (El Hadrami et al, 1997; Ramos et al, 1997).…”

Pretreatment of date palm seedlings with an hypoaggressive Fusarium isolate (AHD) protected them partially from further infection by Fusarium oxysporum f.sp. albedinis (Foa), the Bayoud disease pathogen. No mortality occurred during 2-3 months of incubation in plants pretreated with AHD, as opposed to aggressive isolate (ZAG) inoculated controls where up to 100% mortality was observed 15-30 days after inoculation. Such protection involved biochemical interactions between the host plant and AHD since no direct competition or antagonism was revealed between AHD and ZAG. The examination of the accumulation of phenolics and peroxidase activity, two parameters previously reported to be involved in date palm resistance to Foa, indicated that the response to AHD was correlated with the ability of pretreated date palm tissues to establish a faster defence response in the roots of both susceptible and resistant cultivars. Plants pretreated with AHD accumulated higher amounts of phenolics, mainly nonconstitutive hydroxycinnamic acid derivatives, which play a crucial role in date palm defence against Foa, as previously described by our group. These compounds were accumulated along with the constitutive caffeoylshikimic acids. A faster induction of peroxidase activity in response to Foa was also recorded in plants pretreated with AHD. Given the multi-component nature of these induced responses, AHD could be part of integrated disease management strategies for a sustainable control of the palm tree Bayoud disease.U. S.
