The mechanisms by which herbivores induce plant defenses are well studied. However, how specialized herbivores suppress plant resistance is still poorly understood. Here, we discovered a rice (Oryza sativa) leucine‐rich repeat receptor‐like kinase, OsLRR‐RLK2, which is induced upon attack by gravid females of a specialist piercing‐sucking herbivore, the brown planthopper (BPH, Nilaparvata lugens). Silencing OsLRR‐RLK2 decreases the constitutive activity of mitogen‐activated protein kinase (OsMPK6) and alters BPH‐induced transcript levels of several defense‐related WRKY transcription factors. Moreover, silencing OsLRR‐RLK2 reduces BPH‐induction of jasmonic acid and ethylene but promotes the biosynthesis of both elicited salicylic acid and H2O2; silencing also enhances the production of volatiles emitted from rice plants infested with gravid BPH females. These changes decrease BPH preference and performance in the glasshouse and the field. These findings suggest that OsLRR‐RLK2, by regulating the plant's defense‐related signaling profile, increases the susceptibility of rice to BPH, and that BPH infestation influences the expression of OsLRR‐RLK2, suppressing the resistance of rice to BPH.

“…We previously highlighted, also using different mutant lines, that the defence of Arabidopsis plants against E. oleracea was associated with the JA-dependent pathway, while SA facilitated the herbivore’s fitness (Costarelli et al 2020 ; Ederli et al 2020 ). Therefore, the reduced susceptibility of the B. cinerea -inoculated Arabidopsis plants to insect could be due to the activation of the JA-related pathway, lacking in G. orontii -inoculated plants.…”

In ecosystems, plants are continuously challenged by combined stress conditions more than by a single biotic or abiotic factor. Consequently, in recent years studies on plant relationships with multiple stresses have aroused increasing interest. Here, the impact of inoculation with fungal pathogens with different lifestyles on Arabidopsis plants response to the following infestation with the invasive crop pest Eurydema oleracea was investigated. In particular, as fungal pathogens the necrotroph Botrytis cinerea and the biotroph Golovinomyces orontii were used. Plants exposed to B. cinerea, but not to G. orontii, showed reduced herbivore feeding damage. This difference was associated to different hormonal pathways triggered by the pathogens: G. orontii only induced the salicylate-mediated pathway, while B. cinerea stimulated also the jasmonate-dependent signalling, which persisted for a long time providing a long-term defence to further herbivore attack. In particular, the lower susceptibility of B. cinerea-infected Arabidopsis plants to E. oleracea was related to the stimulation of the JA-induced pathway on the production of plant volatile compounds, since treatment with VOCs emitted by B. cinerea inoculated plants inhibited both insect plant choice and feeding damage. These results indicate that necrotrophic plant pathogenic fungi modulate host volatile emission, thus affecting plant response to subsequent insect, thereby increasing the knowledge on tripartite plant–microbe–insect interactions in nature.

Date palm (Phoenix dactylifera L.) and its fruit possess sociocultural, health and economic importance in Middle East. The date palm plantations are prone to Dubas bug (DB; Ommatissus lybicus DeBergevin; Homoptera: Tropiduchidae) attacks that severely damages the tree's growth and reduces fruit production. However, the transcriptome related datasets are not known to understand how DB activates physiological and gene regulatory mechanisms during infestation. Hence, we performed RnA-Seq of leaf infected with or without DB to understand the molecular responses of date palm seedlings. Before doing that, we noticed that DB infestation significantly increase superoxide anion and malondialdehyde production to two-folds as compared to healthy control. Stress-responsive genes such as proline transporter 2, NADP-dependent glyceraldehyde and superoxide dismutase were found significantly upregulated in infected seedlings. The infection repercussions were also revealed by significantly higher contents of endogenous phytohormonal signaling of jasmonic acid (JA) and salicylic acid (SA) compared with control. These findings persuaded to dig out intrinsic mechanisms and gene regulatory networks behind DB infestation to date palm by RNA-Seq analysis. Transcriptome analysis revealed upregulation of 6,919 genes and down-regulation of 2,695 genes in leaf during the infection process. The differentially expressed genes were mostly belongs to cellular functions (calcium and MAPK), phytohormones (auxin, gibberellins, abscisic acid, JA and SA), and secondary metabolites (especially coumarinates and gossypol). the data showed that defense responses were aggravated by gene networks involved in hypersensitive responses (PAR1, RIN4, PBS1 etc.). in conclusion, the results revealed that date palm's leaf up-regulates both cellular and phytohormonal determinants, followed by intrinsic hypersensitive responses to counter infestation process by Dubas bug. Date palm (Phoenix dactylifera L.) is one of the oldest fruits crop and has played particularly important role in the culture, economy and well-being of the people of Arabian region 1. It is widely grown in arid and semi-arid region , and distributed across 24 countries 2. The fruit is an important part of dietary intake due to its significant nutritional values. Like other countries in Arabian Peninsula, there are more than 300 date palm cultivars in Oman-the 8th largest producers of date fruits. Although with improved breading and tissue culture technologies, highly resistant varieties are cultivated in oasis, however, still the tree is confronted with pathogenic and insect attacks, hence reducing its growth, yield and production 3,4. The literature shows that date palm fruit decline significantly due to the attack of Dubas bug (Ommatissus lybicus Bergevin, Homoptera: Tropiduchidae) in the Middle East and North Africa, which is considered a major pests 3-5. Dubas bug (DB) was identified by Blumberg for the first time in the Tigris-Euphrates River Valley. Later on, he claimed that DB spread from...
