“…There also was a significant effect of cultivar in one of the JA experiments (more eggs and larvae were found on 'Jasmine' than on 'Rosemont'), but the effect of JA on egg and larval mortality was stronger than the effect of cultivar. Our results are consistent with research in many dicot species that has found the activation of the JA pathway can provide generalized protection against an assortment of herbivorous insects (Inbar et al 1988;Thaler 1999;Omer et al 2000Omer et al , 2001.…”

Herbivore- and Elicitor-Induced Resistance in Rice to the Rice Water Weevil (Lissorhoptrus oryzophilus Kuschel) in the Laboratory and Field

Feeding by herbivores can change plants in ways that make them more resistant to subsequent herbivory. Such induced responses are better-studied in a number of model dicots than in rice and other cereals. In a series of greenhouse and field experiments, we assessed the effects of prior herbivory by the fall armyworm, Spodoptera frugiperda (J.E. Smith) and of exogenous applications of jasmonic acid (JA) on the resistance of rice plants to the rice water weevil, Lissorhoptrus oryzophilus (Kuschel), the major pest of rice in the United States. Prior feeding by S. frugiperda and treatment of plants with exogenous JA resulted in increases in the resistance of plants to the weevil. Increases in resistance were manifested as reduced numbers of eggs and first-instars associated with armyworm-injured or JA-treated plants relative to control plants. In field experiments, there was a transient but significant reduction in the number of immature L. oryzophilus on JA-treated plants relative to untreated plants. To our knowledge, this is the first example of direct induced resistance in rice demonstrated in small-plot field experiments. We discuss the potential for the use of elicitor induced resistance in rice.

“…More experiments are needed to determine the prevalence of induced resistance in roots, but given the current literature, it seems that induced root resistance may not be as common as induced leaf resistance. Interestingly, many studies document that roots do have the potential to increase their resistance, given the right stimulus: The application of JA increases resistance of broccoli roots against D. radicum larvae (Pierre et al 2012) and resistance of grapevine against the root feeding grape phylloxera Daktulosphaira vitifoliae (Omer et al 2000). Furthermore, leaf herbivory induces systemic resistance in roots (Soler et al 2007;Erb et al 2011c;Torrence et al 2011).…”

“…Omer et al [35] investigated on grapevines the effects of exogenous applications of the natural plant inducer, jasmonic acid (JA) on induced resistance to the folivorous Pacific spider mite, Tetranychus pacificus, as well as the root-feeding grape phylloxera, Daktulosphaira vitifoliae. Foliar jasmonic acid application at concentrations that caused no phytotoxicity significantly reduced the production of eggs by both herbivores when they were feeding on treated plants [35]. Negative cross-talk between the jasmonate and salicylate response pathways has been observed on tomato.…”

Elicitors are compounds, which activate chemical defences in plants. Various biosynthetic pathways are activated in treated plants depending on the compound used. The most intensively studied elicitor for manipulating defence pathways in plants is methyl jasmonate, which modifies e.g. the production of terpenoids, the main constituents of conifer oleoresin. Other commonly tested chemical elicitors are salicylic acid, methyl salicylate and benzothiadiazole, which affect production of phenolic compounds in plants. Both jasmonate-based and salicylate-based elicitors have been shown to have suppressive effects on fungal diseases and insect pests of plants. So far, knowledge regarding the efficiency of elicitor treatments for enhancing pest and fungal disease resistance of conifer seedlings is very limited. We review current knowledge of the effect of these elicitor compounds on pest and disease resistance in plants, and we analyze the potential pros and cons of using elicitors for future pest management strategies in forest nurseries.
