“…Jasmonic acid is also responsible for the delivery of long-distance signaling molecules in several plant species (Schilmiller and Howe, 2005; Heil and Ton, 2008; Sogabe et al, 2011; Ankala et al, 2013). Interestingly, JA-signaling has also been described as the main pathway in ISR against aboveground herbivores and is stimulated by root-associated microbes (Van Oosten et al, 2008; Pineda et al, 2010; Jung et al, 2012).…”

Plants are members of complex communities and function as a link between above- and below-ground organisms. Associations between plants and soil-borne microbes commonly occur and have often been found beneficial for plant fitness. Root-associated microbes may trigger physiological changes in the host plant that influence interactions between plants and aboveground insects at several trophic levels. Aboveground, plants are under continuous attack by insect herbivores and mount multiple responses that also have systemic effects on belowground microbes. Until recently, both ecological and mechanistic studies have mostly focused on exploring these below- and above-ground interactions using simplified systems involving both single microbe and herbivore species, which is far from the naturally occurring interactions. Increasing the complexity of the systems studied is required to increase our understanding of microbe–plant–insect interactions and to gain more benefit from the use of non-pathogenic microbes in agriculture. In this review, we explore how colonization by either single non-pathogenic microbe species or a community of such microbes belowground affects plant growth and defense and how this affects the interactions of plants with aboveground insects at different trophic levels. Moreover, we review how plant responses to foliar herbivory by insects belonging to different feeding guilds affect interactions of plants with non-pathogenic soil-borne microbes. The role of phytohormones in coordinating plant growth, plant defenses against foliar herbivores while simultaneously establishing associations with non-pathogenic soil microbes is discussed.

“…The phytohormones SA, jasmonic acid (JA), and ethylene (ET) activate herbivore induced signals via independent, antagonistic, and synergistic pathways and interface with other hormones auxin, abscisic acid (ABA), brassinosteroid (BR), gibberellins (GA), and cytokinin (CK) [25][26][27][28]. Additionally, as part of the defense mechanisms against phloem-feeding insects and other herbivores, plants are known to alter secondary metabolites, glutathione S-transferases (GSTs), peroxidases, and redox homeostasis [19,[29][30][31].…”

“…Ribosome inactivating protein (RIP) and allene oxide synthase (AOS) were locally induced by mechanical wounding (Engelberth et al, 2012), and RIP2 accumulated in the leaves of an insect-resistant inbred maize line upon caterpillar attack (Chuang et al, 2014). When the fall armyworm (Spodoptera frugiperda) attacked maize leaves, RIP, AOS, and other genes were differentially expressed in the roots (Ankala et al, 2013). Therefore, the signaling response to foliar herbivory can be conveyed to the roots from leaves.…”

Maize originated in the highlands of Mexico approximately 8700 years ago and is one of the most commonly grown cereal crops worldwide, followed by wheat and rice. Abiotic stresses (primarily drought, salinity, and high and low temperatures), together with biotic stresses (primarily fungi, viruses, and pests), negatively affect maize growth, development, and eventually production. To understand the response of maize to abiotic and biotic stresses and its mechanism of stress tolerance, high-throughput omics approaches have been used in maize stress studies. Integrated omics approaches are crucial for dissecting the temporal and spatial systemlevel changes that occur in maize under various stresses. In this comprehensive analysis, we review the primary types of stresses that threaten sustainable maize production; underscore the recent advances in maize stress omics, especially proteomics; and discuss the opportunities, challenges, and future directions of maize stress omics, with a view to sustainable food production. The knowledge gained from studying maize stress omics is instrumental for improving maize to cope with various stresses and to meet the food demands of the exponentially growing global population. Omics systems science offers actionable potential solutions for sustainable food production, and we present maize as a notable case study.
