“…On the other hand, the functions of SA in plant defence response against pathogens such as fungi and viruses have also been described(Pieterse et al. ). It has been reported that a negative crosstalk between the SA and JA pathways is important role for defence against herbivores (Leon‐Reyes et al.…”

The effect of a thrips-non-transmissible Tomato spotted wilt virus (TSWV) on insect-host interactions between thrips and Arabidopsis thaliana was analysed. A wild-type TSWV virulent isolate and a TSWV isolate that induces mild symptoms on inoculated plants (TSWV-Mo) were used in this study, and TSWV-Mo isolate was obtained by single local lesion isolation using Petunia x hybrid after several passages on Nicotiana rustica plants. In transmission test, although wild-type TSWV (TSWV-wt) was transmitted by two thrips species (transmission ratio; Frankliniella occidentalis, 25%; Thrips tabaci, 10%; and T. palmi, 0%), none of the thrips transmitted TSWV-Mo. Feeding damage by F. occidentalis in A. thaliana plants was more extensive on TSWV-wt-infected plants than on TSWV-Mo-infected plants, despite comparable preference. Among the markers of plant defences, salicylic acid-regulated genes were upregulated threefold to sixfold by TSWV-wt or TSWV-Mo infection. In contrast, jasmonate-regulated genes and jasmonate/ethylene-regulated genes were not affected by the infections. Pull assays showed that adjacent TSWV-Mo-infected plants were preferred over uninfected plants. In conclusion, our results showed that the transmissibility by thrips of TSWV is not related to preference of vector thrips and suggested that TSWV-Mo-infected plants may be used as attractants for behaviour control of thrips.

“…Phenotypic effects in the tomato plant following induced resistance affected by CHT were manifested in bacterial reduction in plant tissue and reduced wilt incidence [14]. Jasmonic-acid- (JA-) dependent defense responses were suggested to contribute to basal resistance in tomato against different pathogens and to play a role in regulation of systemic defense responses after pathogen attack [15]. …”

We investigated on important parameters of induced resistance in hydroponic tomato (Solanum lycopersicum) against Ralstonia solanacearum using the elicitors chitosan (CHT), salicylic acid (SA), and jasmonic acid (JA). The increase in total phenolic content of roots by the elicitors was significantly higher than control. Most pronounced increase in lignin synthesis was triggered by SA followed by CHT. At 24 h post-elicitation (hpe), the activity of phenylalanine ammonia lyase was 4.5 times higher than control elicited by CHT. The peroxidase activity was about 86 nkat/mg protein at 24 hpe in case of SA and 78 nkat/mg protein in case of CHT. The activity of polyphenol oxidase increased several folds by the elicitors. Cinnamyl alcohol dehydrogenase activity increased to the maximum at 48 hpe under the influence of CHT. The results indicate that the elicitors SA and CHT induced effective defense responses in tomato plants against R. solanacearum. This was evident from reduced vascular browning and wilting symptoms of tomato plants treated with SA and CHT and challenged subsequently with R. solanacearum. This reduced disease incidence in tomato by SA and CHT may be a result of cell wall strengthening through deposition of lignin and the coincident induction of defense enzymes.

“…When tomato seeds were treated with BABA, the resulting plants showed improved resistance against biotrophic fungal pathogen powdery mildew ( Oidium neolycopersici ). BABA is a non‐protein‐amino acid which is rarely found in nature, and has been known to induce or prime plant defenses against a wide range of tomato biotic stresses including microbial pathogens, nematodes, and aphids, and against abiotic stresses as well (Pieterse et al ., ). It is generally recognized that induction of plant defense against arthropod herbivores and necrotrophic pathogens is dependent on JA biosynthesis pathway, and defense against biotrophic pathogens is regulated by salicylic acid (SA)‐dependent defense pathway, and JA and SA often act antagonistically (Pieterse et al ., ).…”

Priming of antiherbivore defensive responses in plants

Defense priming is defined as increased readiness of defense induction. A growing body of literature indicates that plants (or intact parts of a plant) are primed in anticipation of impending environmental stresses, both biotic and abiotic, and upon the following stimulus, induce defenses more quickly and strongly. For instance, some plants previously exposed to herbivore-inducible plant volatiles (HIPVs) from neighboring plants under herbivore attack show faster or stronger defense activation and enhanced insect resistance when challenged with secondary insect feeding. Research on priming of antiherbivore defense has been limited to the HIPV-mediated mechanism until recently, but significant advances were made in the past three years, including non-HIPV-mediated defense priming, epigenetic modifications as the molecular mechanism of priming, and others. It is timely to consider the advances in research on defense priming in the plant-insect interactions.
