“…NaMPK4 -silenced plants ( irNaMPK4 ) are impaired in their response to ABA- and H 2 O 2 -mediated stomatal closure. NPK4 is also involved in defense against aphids, invading pathogenic bacteria and Alternaria alternata (tobacco pathotype) ( Slavov et al, 2004 ; Hettenhausen et al, 2012 ; Sun et al, 2014 ; Guo et al, 2017 ).…”

Mitogen-activated protein kinase (MAPK) modules play key roles in the transduction of environmental and developmental signals through phosphorylation of downstream signaling targets, including other kinases, enzymes, cytoskeletal proteins or transcription factors, in all eukaryotic cells. A typical MAPK cascade consists of at least three sequentially acting serine/threonine kinases, a MAP kinase kinase kinase (MAPKKK), a MAP kinase kinase (MAPKK) and finally, the MAP kinase (MAPK) itself, with each phosphorylating, and hence activating, the next kinase in the cascade. Recent advances in our understanding of hormone signaling pathways have led to the discovery of new regulatory systems. In particular, this research has revealed the emerging role of crosstalk between the protein components of various signaling pathways and the involvement of this crosstalk in multiple cellular processes. Here we provide an overview of current models and mechanisms of hormone signaling with a special emphasis on the role of MAPKs in cell signaling networks.One-sentence summary: In this review we highlight the mechanisms of crosstalk between MAPK cascades and plant hormone signaling pathways and summarize recent findings on MAPK regulation and function in various cellular processes.

Elevated CO2 and O3 can affect aphid performance via altering plant nutrients, however, little is known about the role of plant secondary metabolites in this process, especially for aphids feeding behaviors. We determined the effects of elevated CO2 and O3 on the growth and phenolics of alfalfa (Medicago sativa) and feeding behaviors of the pea aphids (Acyrthosiphon pisum) and cowpea aphids (Aphis craccivora). Elevated CO2 improved plant growth, but could not completely offset the negative effects of elevated O3. Elevated O3 increased foliar genistin content at the vegetative stage, increased ferulic acid at the reproductive stage, and elevated CO2 increased those at both stages. Simultaneously elevated CO2 and O3 increased foliar ferulic acid content at the reproductive stage and increased genistin content at both stages. For pea aphids, feeding efficiency was reduced under elevated CO2 at the reproductive stage and decreased under elevated O3 at the vegetative stage. For cowpea aphids, feeding efficiency was increased under elevated CO2 at the vegetative stage and decreased under elevated O3 at both stages. Simultaneously elevated CO2 and O3 decreased both aphids feeding efficiency. We concluded that CO2 and O3 independently or interactively had different effects on two aphids feeding behaviors through altering foliar ferulic acid and genistin contents.

“…In response to aphid feeding, plants produce phytohormone-dependent defences (Goggin et al 2007). Under an elevated CO 2 concentration, such defences could be altered or increased, and thus affect the amount of time spent by the aphids searching for phloem (Guo et al, 2014(Guo et al, , 2017. Because the aphid stylet is of a finite length, changes in the depth to which the insect must penetrate to reach the phloem, as well as changes in the quality of the phloem sap, might also modify aphid feeding performance (Faria et al, 2007;Guo et al, 2013).…”

Today and tomorrow: impact of climate change on aphid biology and potential consequences on their mutualism with ants

Recent studies about mutualism consider the complexity and versatility of the relationship, in addition to highlighting the importance of the cost/benefit balance between the two protagonists. Because species interactions are highly dependent on the environment, the climate changes foreseen for the coming years are expected to have significant impacts on the evolution of mutualistic interactions. Among mutualisms, the aphid–ant interaction is well documented, partly explained by the pest status of aphids. This literature review focuses on the impact of climate change (particularly atmospheric carbon dioxide concentration and temperature) on aphid biology and the potential consequences with respect to their mutualistic interactions with ants. We provide an overview of the published reports concerned with the effects of temperature and carbon dioxide on aphids, for which a positive, a negative or no effect has been highlighted. We then discuss how climatic changes can alter four major components of aphid biology that are shaping their interaction with ants: (i) aphid population growth; (ii) aphid behaviour and mobility; (iii) honeydew production and composition; and (iv) semiochemistry. Finaly, we discuss the limitations of such studies on aphid–ant mutualism, as well as the information that is still needed to predict how climate change might impact this type of relationship.
