Summary: Arbuscular mycorrhizal fungi may influence competitive plant interactions, with Lolium multiflorum being the strongest competitor in the presence of AMF. Nitrogen fertilization did not affect the competitive balance, but phosphorus fertilization gave Lolium a competitive advantage over Trifolium. The differential C-P trade benefits driven by AMF may play a role in shaping the competitive outcomes between these two pasture species.

Summary: The study used transcriptomics to investigate gene expression in mycorrhizal roots of a terrestrial mixotrophic orchid that associates with ectomycorrhizal fungi, providing new insights into orchid-fungus interactions and suggesting amino acids as the main nitrogen source in mycorrhizal roots. Further research is needed to understand if specific additional genes or fine-tuned regulation of common components are responsible for the specificities of orchid mycorrhiza.

Summary: The study investigated the distribution and diversity of Ceratobasidium OMF in orchids and soils across Australia, revealing common cross-continental fungi with ranges exceeding that of their host orchids. This suggests these fungi do not limit their host orchids' distributions at large spatial scales. The majority of OTUs were found in southern Australia, with some extending into central and northern regions, showcasing their tolerance for a wide range of environmental conditions.

Summary: Mycorrhizal associations play a crucial role in orchid germination and seedling establishment, potentially impacting the distribution and abundance of orchids in natural conditions. The mycoheterotrophic orchid Gastrodia confusoides displays random aboveground spatial patterns of distribution within bamboo forests, possibly due to the scattered distribution of litter-decaying fungi. Our study provides evidence that the abundance of litter-decaying fungi varies randomly within the bamboo forest and independently from G. confusoides adults.

Summary: Mycoheterotrophic plants often associate with a limited range of mycorrhizal fungi, and this specialization is considered significant in their evolution. This study investigated the mycorrhizal communities of two Pyrola species and an ectomycorrhizal tree, revealing a consistent fungal association in the seemingly broadly interacting Pyrola species, suggesting the development of mycorrhizal specialization within the genus Pyrola during mycoheterotrophic evolution.

Summary: Mycorrhizal symbioses have a significant impact on plant performance and ecosystem dynamics. Plant mycorrhizal traits offer valuable insights into belowground functionality. This study explores the correlation between phylogenetics, environmental factors, and plant mycorrhizal traits using a plant phylogenetic mega-tree and high-resolution climatic and edaphic data layers. The findings suggest that plant mycorrhizal type is more phylogenetically conserved, while environmental variables play a larger role in determining mycorrhizal status.

Summary: Inoculation with arbuscular mycorrhizal (AM) fungi can enhance the phytoremediation of soils polluted by polycyclic aromatic hydrocarbons (PAHs) by increasing plant biomass and improving soil characteristics. This meta-analysis showed that AM inoculation significantly decreased soil PAHs concentration and had positive effects on plant biomass and soil biological activity. Although effects varied with different factors, few negative effects of AM inoculation were observed. This study confirmed the feasibility of using AM fungi to enhance the phytoremediation of PAHs-contaminated soil.

Summary: This study examined the effects of native arbuscular mycorrhizal (AM) fungal communities from conventionally managed arable soils on plant growth and nutrient uptake. The results showed that arbuscular mycorrhiza had a negative correlation with P availability, and the positive effects of mycorrhiza were more pronounced in a small subset of soils.

Summary: Orchid mycorrhiza (OM) is a unique symbiosis between plants and fungi, where the mycorrhizal fungus provides carbon, phosphorus, nitrogen, and possibly sulfur to the host orchid. This study investigated sulfur metabolism and transfer in the OM symbiosis using advanced imaging techniques and gene expression analysis. The findings revealed that the fungi actively contribute to sulfur supply, and the transfer most likely occurs in organic forms. This study adds new insights into the nutritional framework of OM symbiosis.

Summary: Changes in the timing of development within a lineage have a significant impact on floral diversification. This study compared petal development across species in the genus Schizanthus and found that transitions in pollinators were associated with lower lip diversification. Different heterochronic processes shape morphological variation and promote adaptive evolution in floral structures of this genus.

Summary: The parasitism of Tristerix aphyllus negatively affects the fitness of Echinopsis chiloensis, particularly impacting summer photosynthesis. While cacti with higher nitrogen concentrations to the south show improved overall fitness, there is no strong impact on cactus physiology overall. The response of E. chiloensis to T. aphyllus infection is sensitive to environmental changes and could be greatly impacted by desertification projected in the area due to climate change.

Summary: This paper presents a new species of Nicotiana found in Chile, endemic to the coast of the Coquimbo region. Through molecular analysis, it is classified within the N. sect. Paniculatae, as a sister species to N. cordifolia from the Juan Fernandez islands. The new species is considered critically endangered due to its restricted and fragmented distribution, small population size, and the threat of urbanization and mining activities to the conservation of the area's biodiversity.

Summary: The pathogenesis of SARS-CoV-2 involves the interaction between a spike protein and the angiotensin II-converting enzyme receptor, leading to inflammatory responses and severe disease in some cases. Recent studies have shown that angiotensin-(1-7) has the potential to control COVID-19 severity due to its anti-inflammatory and other beneficial effects. Therefore, the use of convalescent plasma conjugated therapy and Ang (1-7) agonists is recommended for COVID-19 treatment. However, more clinical evidence is needed to establish the therapeutic usage of this peptide.

Summary: This study aimed to describe outcomes and complications associated with the use of peripherally inserted central venous catheters in neonates and identify risk factors for major complications. The results showed that catheter use was long-lasting with a low rate of major complications, which were more common in extremely preterm infants. Infections were associated with an increased number of punctures and durations over 14 days.
