“…PIP1, SCOOPs, CEP4, Systemin, and Hypsys peptides induce MAPK activation in their respective species of origin [ 14 , 22 , 27 , 33 , 65 ]. Additionally, Systemin primes MPK3 and MPK6 phosphorylation upon Plectosphaerella cucumerina infection in Arabidopsis thaliana [ 66 ]. Parallelly, Calcium-dependent protein kinases (CDPKs), which are Ca 2+ sensor protein kinases, are also activated upon several danger signals’ perception and trigger downstream defense responses [ 67 ].…”

The plant immunity system is being revisited more and more and new elements and roles are attributed to participating in the response to biotic stress. The new terminology is also applied in an attempt to identify different players in the whole scenario of immunity: Phytocytokines are one of those elements that are gaining more attention due to the characteristics of processing and perception, showing they are part of a big family of compounds that can amplify the immune response. This review aims to highlight the latest findings on the role of phytocytokines in the whole immune response to biotic stress, including basal and adaptive immunity, and expose the complexity of their action in plant perception and signaling events.

“…Due to its recognized role in inducing a primed state in plants, the application of systemin may be an important component of ecologically-based pest management program. In fact, some few studies have been already showed that the exogenous application of systemin enhances resistance to the pathogens Botrytis cinerea and Plectosphaerella cucumerina in different plant species (Molisso et al 2021;Pastor-Fernández et al 2022) and to the noctuid moth Spodoptera littoralis and the aphid Macrosiphum euphorbiae in tomato (Coppola et al 2015(Coppola et al , 2017(Coppola et al , 2019. As far as we known, the effect of systemin in enhancing the olive tree ability to resist olive fruit y attacks has never been tested.…”

“…These peptides are released upon pest or pathogen attack, and they trigger a cascade of plant defences, increasing plant immune response (Pastor-Fernández et al 2020). Systemin (Sys), a peptide comprising 18 amino acids, is one of the most known peptide reported to play an important role in regulating the resistance of plants against herbivorous pests (Coppola et al 2015(Coppola et al , 2017(Coppola et al , 2019 and phytopathogens (Coppola et al 2015;Molisso et al 2021;Pastor-Fernández et al 2022).…”

The olive fruit fly, Bactrocera oleae (Rossi), is a key pest of the olive crop, whose control relies mostly on the use of insecticides. Plant peptides may represent a more environmentally-friendly tool to manage olive fly, due to their recognized role to activate and/or prime plant defence responses against pests. In this work, behavioural experiments (no-choice and two-choice) and analysis of volatile compounds were carried out in order to evaluate the impact of the exogenous application of the peptide systemin to olive tree on olive fly infestation, and to elucidate its mode of action to prime plant defence. The treatment of olive branches with 10 nM systemin showed to confer protection against olive fly, by reducing significantly the ovipositions (up to 3.0-fold) and the number of infested fruits (up to 2.9-fold) when compared to not-treated branches. This protective effect was even detected in neighbouring not-treated branches, suggesting the ability of systemin to trigger plant-to-plant communication. The deterrent activity of the primed olives was associated with the emission of the volatiles 2-ethyl-1-hexanol, 4-tert-butylcyclohexyl acetate and 1,2,3-trimethyl-benzene, which were negatively correlated with oviposition and fly infestation. Systemin also showed to trigger the biosynthesis of specific volatiles (esters) in olives in response to fly attacks. Overall, the observed protection conferred by systemin against olive fly is likely due to the emission of specific volatiles that can act as a defence and/or as signalling molecules to upregulate the plant defence response. Thus, systemin represents a novel and useful tool to manage olive fruit fly.
