Summary: This study proposes a mechanism for the transformation of plant-fungal endophyte symbiosis under stress, suggesting that plant physiological responses can affect the outcome of the symbiotic relationship. Additionally, it suggests that endophytes may protect the symbiosis by inducing plant defense hormone responses and antioxidants.

Summary: Agricultural crops infected with vector-borne pathogens can have varied fitness outcomes for vector hosts, but overall phytopathogens have a neutral effect on their host's fitness. Various transmission strategies and direct or indirect effects of phytopathogens do not result in divergent fitness outcomes for the vector. Our findings highlight the importance of pathosystem-specific approaches for vector control.

Summary: Plants interact with multiple above- and below-ground organisms simultaneously, with their symbiotic relationships ranging from mutualism to parasitism. Competition between different symbionts for host plant resources may heavily influence resource allocation, highlighting the need for a more holistic understanding of below-ground interactions. By applying isotope tracing and nutrient budgeting methods, as well as conducting experiments involving multiple plant hosts connected by common mycelial networks, it may be possible to reveal the impact of competing symbionts on carbon and nutrient flows at ecologically important scales.

Summary: Plants form beneficial symbioses with endophytes, arbuscular mycorrhizal fungi, and nitrogen-fixing rhizobia, promoting plant nutrition and growth while enhancing host plant tolerance to environmental stress. Salicylic acid plays a crucial role in plant defense against pathogens and has been shown to impact plant-microbe symbiotic interactions.

Summary: Defensive symbionts in the host microbiome can provide protection from infection or reduce the harms of being infected. However, the consequences of introducing a defensive symbiont for parasite evolution and how the symbiont may coevolve with the parasite have been relatively understudied.

Summary: Fungal secondary metabolites (FSMs) can manipulate plant community dynamics by influencing the establishment of co-habitating organisms, even though their presence may not be essential for the survival of the producer. The biological function of FSMs may indirectly benefit the producer by altering the dynamics of surrounding organisms, suggesting a potential ecological impact. The contribution of FSMs to plant-associated interaction networks highlights their role in affecting the host in previously unclear ways.

Summary: Symbiosis, the living together of unlike organisms as symbionts, is common in nature, occurring across all scales of life. Studying the ecological and evolutionary dynamics of symbiosis poses challenges due to long time scales, limited experimental control, weak resolution in quantifying interactions, and idiosyncrasies of model systems. Digital evolution, however, offers opportunities with perfect data tracking, experimental manipulations, and the ability to observe thousands of generations in minutes, making it a key technique in studying symbioses.

Summary: Interactions between species are known to promote diversification, but the mechanisms behind the formation of new species are still unclear. This study examined the population genetic structure of host plants and associated species to understand how interactions contribute to diversification. The results showed that the population structure of associated species often paralleled that of their hosts, with antagonistic interactions having a stronger influence on diversity compared to mutualistic interactions.

Summary: In nature, plants interact with multiple mutualistic partners, and these interactions can be influenced by competition for resources, alteration of plant traits, and environmental conditions. This study focused on the effects of global warming on interactions between plants and their mutualistic partners. The results showed that warming affected the benefits plants received from rhizobium resource mutualists but not ant mutualists, and it also altered plant investment in all mutualists. Additionally, mutualist partners were found to interact and affect the availability of plant-produced rewards. These findings highlight the potential impact of global changes on mutualistic relationships and the complex interactions among multiple mutualists associated with a shared host.

Summary: Cobalt is proposed as a potentially essential micronutrient for plants, particularly important for leguminous plants and some lower plants, aiding in nitrogen fixation and plant metabolism. However, excessive cobalt can be toxic to plants, causing nutrient deficiencies and leaf discoloration. Further research on the role of cobalt in plant metabolism is needed.

Summary: This study examines the (co)evolution of host-associated microbiomes and finds that microbial and host fitness tend to trade-off rather than generating conflict. The results highlight the importance of quantifying microbial relative fitness for understanding microbiome evolution and improving host fitness.

Summary: Symbioses play a significant role in biological influence, with particular relevance for disease, evolutionary transitions, and ecological communities. The extent to which symbiont phylogenies mirror those of their hosts reveals insights into evolutionary processes. Vertical transmission and mutualism are key factors promoting closer ties between hosts and symbionts, with symbiont phylogeny broadly reflecting host phylogeny across biodiversity and life history.

Summary: The incidence of epichloid endophytes can reduce host competitive ability and provide associational protection to neighboring non-endophytic plants. The symbiosis between ryegrass and epichloid endophytes may increase crop yield through positive neighborhood effects.

Summary: This study demonstrates that fungal endophytes can mitigate the oxidative damage caused by maternal ozone exposure in progeny plants, ultimately enhancing their survival. Additionally, the presence of endophytes was associated with a higher concentration of proline, a defense compound that aids in stress control, showing that hereditary microorganisms can play a role in helping plants adapt to environmental changes.

Summary: The research found that endophytes have different effects on the symbiotic relationship between invasive and noninvasive grasses with arbuscular mycorrhizal fungi (AMF), reducing the mycorrhization only on invasive species without impacting their biomass levels, thereby facilitating host plant establishment and subsequent invasion.

Summary: The study evaluated the impact of repeated glyphosate application in Pampas on the abundance and community structure of Pseudomonas bacteria. Results showed a reduction in culturable pseudomonads with repeated herbicide application in the field, while under greenhouse conditions, glyphosate applied to bare soil did not affect pseudomonad abundance or community structure.

Summary: The combination of above- and below-ground litter produced by plants with endophyte infection increased the germination speed and seedling emergence of Trifolium repens, while the below-ground litter of endophyte-infected plants decreased the establishment of T. repens. These effects are likely due to the release of endophyte-induced secondary metabolites.

Summary: This study used microfluidic chips to investigate foraging strategies and habitat modification of Rhizophagus irregularis symbiotically associated with carrot roots. The researchers found that AMF hyphae can forage over long distances, prefer straight passages, and show branching induction when encountering obstacles. They also observed bi-directional transport of cellular content inside the hyphae and strategic allocation of biomass within the mycelium. Additionally, the AMF hyphae modified the pore-spaces in the chips by clogging them with irregularly shaped spores. These findings have important implications for understanding the impact of AMF on water retention in soils.
