“…These mycorrhizal connections are referred to as common mycorrhizal networks (CMNs). It has been shown that sugars (monosaccharides), amino acids, lipids, water, and micronutrients can all be transported via CMNs [33,34,117]. In addition to nutrient exchange, CMNs have been shown to carry infochemicals, including plant hormones, enzymes, allelochemicals, and secondary compounds not involved in growth and development of the plant [118][119][120].…”

“…Plant-plant communication through informative chemical cues or signals-also known as infochemicals-can occur above-and belowground [31,32]. The aboveground interactions are largely mediated by biogenic volatile organic compound (BVOC) emissions and belowground interactions by root-associated pathways involving common mycorrhizal networks (CMNs), volatile emissions, and chemical exudates [25,33,34]. The CMN-based communication in the rhizosphere can be considered "wired" and the BVOC-based communication aboveground considered "wireless," indicating a complexity of information processing that can depend on the medium through which signals traverse.…”

“…Plant-plant communication has been reviewed in the context of the diversity of communication signals and its role in crop and produce plantations [34][35][36]. In this review, we focus on addressing how these processes can affect herbivory in forests which are more diverse in species richness (both plant and animal) compared to agricultural systems.…”

Tree Communication: the Effects of “Wired” and “Wireless” Channels on Interactions with Herbivores

Purpose of Review Approximately 40 years ago, key papers indicating that volatile chemicals released by damaged plants elicited defense-related changes in their neighbors, brought prominence to the idea of plant communication. These studies were conducted with several tree species and the phenomenon observed was dubbed “talking trees.” Today there is a wealth of evidence supporting the idea that plants can send and receive information both above and belowground. However, while early reports of plant-plant communication concerned trees, the literature is now heavily biased towards herbaceous plants. The purpose of this review is to highlight recent research on tree-tree communication with an emphasis on synthesizing knowledge on the ecological relevance of the process. Recent Findings Aboveground, information is often provided in the form of biogenic volatile organic compounds (VOCs), which are released by both undamaged and damaged plants. The blends of VOCs released by plants provide information on their physiological condition. Belowground, information is conveyed through mycorrhizal networks and via VOCs and chemical exudates released into the rhizosphere. Recent findings have indicated a sophistication to tree communication with more effective VOC-mediated interactions between trees of the same versus a different genotype, kin-group, or chemotype. Moreover, common mycorrhizal networks have been shown to convey stress-related signals in intra- and interspecific associations. Together these two forms of communication represent “wireless” and “wired” channels with significance to facilitating plant resistance to herbivores. Summary In this review, we examine tree-tree communication with a focus on research in natural forest ecosystems. We particularly address the effects of tree-tree communication on interactions with herbivorous insects. Aboveground and belowground interactions are both reviewed and suggested implications for forest management and future research are presented.

Climate change is likely to have severe impacts on food security in the topics as these regions of the world have both the highest human populations and narrower climatic niches, which reduce the diversity of suitable crops. Legume crops are of particular importance to food security, supplying dietary protein for humans both directly and in their use for feed and forage. Other than the rhizobia associated with legumes, soil microbes, in particular arbuscular mycorrhizal fungi (AMF), can mitigate the effects of biotic and abiotic stresses, offering an important complementary measure to protect crop yields. This review presents current knowledge on AMF, highlights their beneficial role, and explores the potential for application of AMF in mitigating abiotic and biotic challenges for tropical legumes. Due to the relatively little study on tropical legume species compared to their temperate growing counterparts, much further research is needed to determine how similar AMF–plant interactions are in tropical legumes, which AMF species are optimal for agricultural deployment and especially to identify anaerobic AMF species that could be used to mitigate flood stress in tropical legume crop farming. These opportunities for research also require international cooperation and support, to realize the promise of tropical legume crops to contribute to future food security.

Mercury (Hg) pollution of soil and water environments is a major global threat to human health, agri‐food systems and ecosystems and industrial activities mainly coal combustion augmented their content in different environmental media. Bioremediation is a nature‐based solution involving microbial‐ and plant‐based (phytoremediation) technologies that clean‐up Hg contaminated sites. Here, we review Hg‐resistant bacteria and how latest insights in our understanding of the cellular and biochemical mechanisms of the mer operon genes responsible for Hg resistance and transformation have facilitated developments in microbial Hg‐bioremediation. We also review the phytoremediation mechanisms, including those of bacterial‐ and fungi‐assisted phytoremediation processes, which have shown promising results in reducing Hg2+ to Hg0. This review provides a detailed knowledge of novel Hg bioremediation mechanisms and methods. Consequently, microbial‐ and phyto‐based bioremediation technologies have a critical role in the reclamation of Hg‐contaminated environments and the protection of human health and ecosystems.
