Chemical defence substances such as phenolics and terpenoids (please see ► Chap. 3)

Plant-plant communication via volatiles to ‘warn’ neighbouring plants

Plant-insect interactions , e.g. extrafloral nectar secretion from wounds of bittersweet nightshade (Solanum dulcamara) to attract ants to defend the plant against herbivory by flea beetle larvae (Léon et al. 2001; Heil and Ton 2008; Bhattacharya et al. 2010; Steppuhn et al. 2016)

As our interest lies in improving the inner quality of crops, this chapter will focus on stimulating the wound-induced chemical defence of the plant in order to obtain substances beneficial to human health (◘ Table 10.1). Responses to wounding can be local, systemic or both. Healing and repair are locally activated reactions, whereas herbivore deterrence can be locally and systematically activated. Wound-induced responses include changes in metabolic processes and in the expression of wound-inducible defence genes. Gene expression underlies the generation, perception, translocation and transduction of signals. Many structurally different molecules are involved in the regulation of wound signalling . Examples are:The oligopeptide systemin
