“…Recent advances in the use of luminescent probes and reporter gene systems facilitate the detection of multiple ROS ( Ortega-Villasante et al, 2018 ), and while a recent study did not detect any effects of the pea aphid on hydroxyl radical ( ⋅ OH) abundance in pea plants ( Łukaszewicz et al, 2021 ), preliminary data suggests that the green peach aphid may induce singlet oxygen ( 1 O 2 ) accumulation in Arabidopsis ( Fischer, 2021 ). In addition, Russian wheat aphid infestation on wheat induces accumulation of nitric oxide, a reactive nitrogen species that interacts with ROS to regulate other stress responses ( Moloi and van der Westhuizen, 2014 ; Moloi et al, 2014 ).…”

“…The Russian wheat aphid induces NO accumulation and nitrate reductase activity within 3 h in a resistant wheat cultivar but not in a near-isogenic susceptible cultivar ( Moloi and van der Westhuizen, 2014 ). Exogenous treatments with a NO donor, sodium nitroprusside (SNP) reduces the intrinsic rate of increase of the Russian wheat aphid on wheat ( Moloi et al, 2014 ) and decreases the feeding behavior and fecundity of the pea aphid on pea ( Woźniak et al, 2017 ). Together, these results suggest that NO contributes to plant defenses against aphids.…”

“…Together, these results suggest that NO contributes to plant defenses against aphids. Furthermore, Russian wheat aphids also trigger accumulation of peroxynitrite, a product generated when NO reacts with O 2 – radicals ( Moloi et al, 2014 ). This supports the hypothesis that NO interacts with ROS to regulate plant responses to aphids.…”

Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide are produced in plants in response to many biotic and abiotic stressors, and they can enhance stress adaptation in certain circumstances or mediate symptom development in others. The roles of ROS in plant-pathogen interactions have been extensively studied, but far less is known about their involvement in plant-insect interactions. A growing body of evidence, however, indicates that ROS accumulate in response to aphids, an economically damaging group of phloem-feeding insects. This review will cover the current state of knowledge about when, where, and how ROS accumulate in response to aphids, which salivary effectors modify ROS levels in plants, and how microbial associates influence ROS induction by aphids. We will also explore the potential adaptive significance of intra- and extracellular oxidative responses to aphid infestation in compatible and incompatible interactions and highlight knowledge gaps that deserve further exploration.

“…The NO signaling pathway orchestrates defensive responses to a wide array of stresses, including drought, heavy metals, temperature extremes, salinity, and pathogens (Baudouin, 2011;Corpas et al, 2011;Kwan et al, 2015). Recently, NO has proved to be a multifunctional signaling molecule in plant defense against herbivore pests (Moloi et al, 2015). The involvement of NO in defense against tobacco hawkmoths, Manduca sexta, has been proven in tobacco plants (Wünsche et al, 2011a).…”

Nitric Oxide Boosts Bemisia tabaci Performance Through the Suppression of Jasmonic Acid Signaling Pathway in Tobacco Plants

The intimate relationships between plants and insects start with herbivory, which can be traced back to approximately 420 million year ago. Like many other relationships, a plant-insect interaction can be mutualistic, commensalistic, or antagonistic. Within antagonistic relationships, plants deploy inducible defense to insect phytophagy. Insects, however, can evade/suppress effectual plant defenses by manipulating plant defense signaling. Previously, we showed that the sweet potato whitefly, Bemisia tabaci, a global invasive insect pest, can suppress jasmonic acid (JA)-dependent defenses, thereby enhancing their performance on host plants. Given that nitric oxide (NO), a multifunctional signaling molecule, interacts closely with JA signaling pathway, we hypothesized that NO is involved in the suppression of JA defensive responses. Equipped with an integrated approach, we comprehensively examined this overarching hypothesis. We showed that: (1) tobacco plants responded to B. tabaci infestation by accumulating high levels of NO, (2) the exogenous application of sodium nitroprusside, a NO donor, in tobacco plants attracted B. tabaci adults and accelerated nymphal development, whereas plants treated with 2-(4-carboxyphenyl)-4,4,5,5tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), a NO scavenger, repelled B. tabaci adults and prolonged nymphal development, and, more importantly, (3) silencing of NOassociated protein 1, a gene associated with NO accumulation, and cPTIO application disrupted the B. tabaci-mediated suppression of JA in plants. Collectively, these results suggest that: (1) NO signaling is activated by B. tabaci infestation, (2) NO is involved in the suppression of JA-dependent plant defense, and, consequently, (3) NO improves B. tabaci performance on host plants. Our study reflects the remarkable arm race that co-evolved for millions of years between plants and insects and offers a potential novel target (nitric oxide) for the long-term sustainable management of this global invasive pest.

Dichotomous Role of Jasmonic Acid in Modulating Sorghum Defense Against Aphids

The precursors and derivatives of jasmonic acid (JA) contribute to plant protective immunity to insect attack. However, the role of JA in sorghum (Sorghum bicolor) defense against sugarcane aphid (SCA; Melanaphis sacchari), which is considered a major threat to sorghum production, remains elusive. Sorghum SC265, previously identified as a SCA resistant genotype among the sorghum nested association mapping founder lines, transiently increased JA at early stages of aphid feeding and deterred aphid settling. Monitoring of aphid feeding behavior using electropenetrography, a technique to unveil feeding process of piercing-sucking insects, revealed that SC265 plants restricted SCA feeding from the phloem sap. However, exogenous application of JA attenuated the resistant phenotype and promoted improved aphid feeding and colonization on SC265 plants. This was further confirmed with sorghum JA-deficient plants, in which JA deficiency promoted aphid settling, however, it also reduced aphid feeding from the phloem sap and curtailed SCA population. Exogenous application of JA caused enhanced feeding and aphid proliferation on JA-deficient plants, suggesting that JA promotes aphid growth and development. SCA feeding on JA-deficient plants altered the sugar metabolism and induced the levels of fructose and trehalose compared to wild-type plants. Furthermore, aphid artificial diet containing fructose and trehalose curtailed aphid growth and reproduction. Our findings underscore a previously unknown dichotomous role of JA, which may have opposing effects by deterring aphid settling during early stage and enhancing aphid’s proliferative capacity during later-stages of aphid colonization on sorghum plants.
