“…Indirect mechanisms decrease the damage or growth inhibition to the plant with various phytopathogens; these mechanisms include (i) the production of antibiotics and hydrogen cyanide which inhibit the growth of some bacterial and fungal phytopathogens; (ii) the solubilization and subsequent sequestration of iron by bacterially synthesized siderophores, thereby limiting pathogens access to iron and preventing their proliferation; (iii) the synthesis and secretion of fungal pathogen cell-wall-degrading enzymes; (iv) outcompeting phytopathogens by (a) direct competition of nutrients and (b) establishing symbiosis with beneficial microorganism (e.g., arbuscular mycorrhizal fungi) [14], and as a result preventing the phytopathogens from binding extensively to plant roots; (v) the synthesis of many different volatile organic compounds that can inhibit pathogen proliferation; (vi) lowering the amount of potentially inhibitory plant ethylene concentrations by the enzyme ACC deaminase, thereby decreasing plant stress levels; and (vii) the induction of the plant's systemic resistance system, turning on the plant's defenses against various pathogens [4,11,[15][16][17][18].…”

Exuded plant metabolites play an important role in fostering beneficial interactions with the surrounding soil microbiota, thereby helping plants to better adjust to changing environmental conditions. These metabolites act as signals to attract or enhance the colonization of plant roots with specific groups of beneficial microbes and they modulate the dynamics of plant–microbe interactions in fulfilling plant niche-based requirements, directly and/or indirectly. This review emphasizes the expression, levels, modes of action, and net effects of the signaling metabolites that help food crop plants to become colonized by microbes that promote plant growth and development under periods of biotic stress.

Fungi play key roles in the fire‐fuel feedbacks that structure ~40% of the Earth's terrestrial ecosystems, yet a general understanding of fungal responses to fire is lacking. While fire and associated stressor effects on fungi vary based on fire regime components like severity, intensity, and frequency, their influence on fungi can be categorized into three primary phases based on when they influence fungi: during fire, early post‐fire, and later post‐fire. We first identify key fire‐associated phenomic traits and similarities in fungal responses to fire across time. Then, we synthesize this information by linking fire effects to specific fungal traits and response groups to produce trait profiles useful for classifying pyrophilic fungi. The goal of this review is to consolidate fire‐associated phenomic trait data into trait profiles that can be used in combination with fungal genomic data and associated methodologies. These profiles produce an invaluable framework for understanding fungal roles in fire regimes and identify previously unknown trends in fungal responses to fire and associated stressors including heat shock responses, pigmentation, and dispersal into and out of burned environments.

The mutual effect of nutrients on plant–herbivore interactions

Nutrients contained in plant tissues serve as the driving force behind plant and herbivore interactions. The nutrient level, including different kinds of elements and amount of fertilizer, can vary owing to variations in soil composition and this can directly impact plant defense response against herbivores. Plants take up nutrients via two pathways: (i) directly through the root hairs and epidermis and (ii) indirectly through the beneficial microbes that interact with plant roots, such as mycorrhizal fungi and rhizobacteria. The associated microbes, modifying plant nutrient composition, can indirectly affect plant and herbivore interactions. These direct and indirect nutrient uptake pathways adjust plant resistance or tolerance to herbivore attack, as evidenced by factors such as herbivore performance, plant nutrient status, biomass allocation, and compensatory growth. In turn, aboveground and belowground herbivory can exert an effect on nutrient exchange between plants and their associated microbes, primarily on the key resources such as carbon (C), nitrogen (N) and phosphorus (P). Furthermore, it shows that herbivory, in the presence of plant associated beneficial microbes, has no negative effect on plant N and C content. The molecular mechanisms underlying these ecological interactions are being systematically uncovered. In order to outline the research progress in this field, this review synthesizes the current scientific literature regarding the mutual effect of nutrients on plant–herbivore interactions. It aims to support efforts in maintaining the sustainability of ecosystem by optimizing plant defense strategies via managing nutrient variability.
