Common mycorrhizal network: the predominant socialist and capitalist responses of possible plant–plant and plant–microbe interactions for sustainable agriculture

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Plants engage in a variety of interactions, including sharing nutrients through common mycorrhizal networks (CMNs), which are facilitated by arbuscular fungi (AMF). These can promote the establishment, growth, and distribution limited that important for plant turn benefits entire network plants. Interactions between plants microbes rhizosphere complex either be socialist or capitalist nature, knowledge these interactions is equally progress sustainable agricultural practice. In network, resources distributed more evenly, providing all connected plants, such as symbiosis. For example, direct indirect transfer to stimulation growth phytohormones, antagonism toward pathogenic microorganisms, mitigation stresses. AMF would privately controlled profit certain groups hence increasing competition Such invading act saprophytic cause necrotrophy colonizing first case, an excess nutritional may donated receiver transfer. second unequal occurs, certainly favor individual increases interactions. This largely depends on responses predominant (“socialist” “capitalist”) at moment connected. Therefore, some species might benefit from CMNs than others, depending fungal involved association. Nevertheless, disadvantages hard distinguish nature once most colonized simultaneously multiple species, each with its own cost-benefits.

The evolution of signaling and monitoring in plant–fungal networks

Proceedings of the National Academy of Sciences, Год журнала: 2025, Номер 122(4)

Experiments have shown that when one plant is attacked by a pathogen or herbivore, this can lead to other plants connected the same mycorrhizal network up-regulating their defense mechanisms. It has been hypothesized represents signaling, with producing signal warn of impending harm. We examined evolutionary plausibility and hypotheses theoretically. found evolution signaling about an attack requires restrictive conditions, so will rarely be evolutionarily stable. The problem provides benefit competing neighbors, even if they are kin, reduces relative fitness plants. Indeed, selection often more likely push behavior in opposite direction—with dishonestly not occurred, suppressing cue attacked. Instead, we show there two viable alternatives could explain empirical data: 1) process being leads (information attack) which too costly for fully suppress; 2) fungi monitor host plants, detect attacked, then information network. Our results suggest work would required distinguish between these possibilities.

Theoretical analyses for the evolution of biogenic volatile organic compounds (BVOCs) emission strategy

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Опубликована: Май 5, 2024

Abstract Plants emit biogenic volatile organic compounds (BVOCs) as signaling molecules, playing a crucial role in inducing resistance against herbivores. Neighboring plants that eavesdrop on BVOC signals can also increase defenses herbivores or alter growth patterns to respond potential risks of herbivore damage. Despite the significance emissions, evolutionary rationales behind their release and factors contributing diversity such emissions remain poorly understood. To unravel conditions for evolution emission, we developed spatially-explicit model formalizes dynamics emission non-emission strategies. Our considered two effects impact fitness plants: intra-individual communication, which mitigates damage through plant’s own incurring costs, inter-individual alters influence herbivory based from other individuals without costs. Employing mathematical models—the lattice random distribution model—we investigated how spatial structure influenced analysis revealed communication promotes strategy. In contrast, effect favors cheaters who benefit BVOCs released neighboring bearing costs associated with emission. demonstrated narrower scale signaling, higher likelihood evolution. This research sheds light intricate governing implications plant-plant communication.

Biogenic secondary organic aerosol participates in plant interactions and herbivory defense

Science, Год журнала: 2024, Номер 385(6714), С. 1225 - 1230

Опубликована: Сен. 12, 2024

Biogenic secondary organic aerosols (SOAs) can be formed from the oxidation of plant volatiles in atmosphere. Herbivore-induced (HIPVs) elicit defenses, but whether such ecological functions persist after they form SOAs was previously unknown. Here we show that Scots pine seedlings damaged by large weevils feeding on their roots release HIPVs trigger defenses neighboring conspecific plants. The biological activity persisted had been oxidized to SOAs, which indicated receivers displaying enhanced photosynthesis, primed volatile and reduced weevil damage. elemental composition quantity likely determines functions. This work demonstrates plant-derived mediate interactions between plants, highlighting significance ecosystems.

Mycorrhizal Diversity on Roots of Silver Birch and Hybrid Aspen in Clonal Plantations in Northern Europe, Latvia

Forests, Год журнала: 2024, Номер 15(12), С. 2123 - 2123

Опубликована: Дек. 1, 2024

Mycorrhizal fungi contribute to crop growth, yields, and stress tolerance. In forests, common mycorrhizal networks are suggested function as carbon storage transfer substances signals between trees, thus likely contributing their resilience. Such properties crucial under increasing environmental stresses, particularly for clonal forestry. However, communities in relation tree field performances have been scarcely studied. this study, on the roots of clones silver birch hybrid aspen growing distinct trials deep automorphous mineral soils (podzolic fluvic) hemiboreal conditions were assessed using internal transcribed spacer sequencing, bioinformatics, community analysis. The moderately rich/diverse mostly formed by generalist taxa (prevailingly ectomycorrhizal) region. differences among estimated birch, while aspen, productivity was inversely related richness diversity communities, suggesting a top-down effect host. Accordingly, some (e.g., Hyaloscypha sp.) showed clone-specific abundances indicating preference specific These findings prompt further functional studies highlight need consider genetic forest regenerative material maximizing diversity, well more effective inoculation.
