“…8B). In contrast, Ozeretskovskaya et al (2009) reported a positive effect of exogenous JA in reference to periderm proliferation, but this finding opposes the more general view that one of the functions of the wound-induced JA is related to the inhibition of growth by mitotic suppression (Zhang et al , 2008). Concerning SA, its role in wound responses has so far not been elucidated (Vlot et al , 2009).…”

The present study provides new insights on the role of the potato (Solanum tuberosum) suberin feruloyl transferase FHT in native and wound tissues, leading to conclusions about hitherto unknown properties of the phellogen. In agreement with the enzymatic role of FHT, it is shown that its transcriptional activation and protein accumulation are specific to tissues that undergo suberization such as the root boundary layers of the exodermis and the endodermis, along with the tuber periderm. Remarkably, FHT expression and protein accumulation within the periderm is restricted to the phellogen derivative cells with phellem identity. FHT levels in the periderm are at their peak near harvest during periderm maturation, with the phellogen becoming meristematically inactive and declining thereafter. However, periderm FHT levels remain high for several months after harvest, suggesting that the inactive phellogen retains the capacity to synthesize ferulate esters. Tissue wounding induces FHT expression and the protein accumulates from the first stages of the healing process onwards. FHT is up-regulated by abscisic acid and down-regulated by salicylic acid, emphasizing the complex regulation of suberin synthesis and wound healing. These findings open up new prospects important for the clarification of the suberization process and yield important information with regard to the skin quality of potatoes.

“…Concerning SA, its role in wound responses has so far not been elucidated (Vlot et al , 2009). Previous experiments using potato discs have to date been unable to detect any effect of exogenous SA in connection with the healing process (Ozeretskovskaya et al , 2009). However, SA impedes FHT induction after injury (Fig.…”

“…Suberization is a tissue-specific process, whereby cell walls become impregnated with a poly(phenolic) matrix coincident with the deposition of a poly(aliphatic) matrix between the plasmalemma and carbohydrate cell wall (Bernards et al 1999). As a biogenic elicitor, chitosan locally and systemically stimulated wound healing in potato tuber tissues by increasing the number of wound periderm layers, accelerating the development of cork cambium (phellogen), and inducing proteinase inhibitors (Ozeretskovskaia et al 2009).…”

In agriculture, current control of pathogens relies mainly on chemical fertilizers and pesticides. However, alternative solutions are needed due to concerns for public health, environmental protection, and development of resistant pests. Chitosan is a nontoxic, biodegradable biopolymer showing antimicrobial and plant-immunity eliciting properties. Here, we review chitosan antimicrobial activities, modes of action, and the elicitation of plant defense responses. The major points are the following: (1) Chitosan exhibits various inhibitory efficiency against bacteria, fungi, and viruses;(2) the five main modes of action of chitosan are electrostatic interactions, plasma membrane damage mechanism, chitosan-DNA/RNA interactions, metal chelation capacity of chitosan, and deposition onto the microbial surface; (3) the elicitation of plant defense responses by chitosan may be related to various pathogenesis-related proteins, defense-related enzymes, and secondary metabolites accumulation, as well as the complex signal transduction network. The facing problems and strategies for antimicrobial mechanism research and agricultural application of chitosan are also discussed.

“…Potato tuber quality deteriorates due to mechanical damage and wound infections during processing, which led to several physiological and biochemical changes in the damaged tissues. However, chemicals such as arachidonic acid and chitosan, abscisic acid, Scarvone, and aminotriazole were used as regulators for wound healing (Ozeretskovskaya et al, 2009;Woolfson, 2018). Calcium chloride has been used to prevent and control potato diseases (Mohammed et al, 2020).…”

Potato is ranked as the world's fourth most popular staple food with about 5,000 varieties worldwide (Zaheer & Akhtar, 2016).In terms of production, potato is the third most produced crop (405.83 million tons) after rice (862 million tons) and wheat (809.14 million tons) (FAOSTAT, 2019). Food and Agriculture Organization (FAO) regarded potatoes as a solution for world hunger and poverty during the international year of the potato (FAO, 2008). Carbohydrate-rich potatoes are packed with
