Summary: The deployment of plant varieties carrying resistance genes exerts selection pressure on pathogen populations. This study focuses on the poplar rust fungus Melampsora larici-populina, which had a major adaptive event in 1994 leading to the breakdown of a resistance gene. Using a population genetics approach, the study characterizes a candidate avirulence gene and identifies two gene alterations associated with the breakdown of resistance. This study provides evidence of rust fungi adapting to qualitive resistance breakdown through genetic variation.

Summary: The shifts in adaptive strategies during ecological succession are crucial to ecology, particularly in communities of arbuscular mycorrhizal fungi (AMF) mutualistic with sorghum. This study reveals the correlation between AMF species shift and sorghum genes involved in signaling, nutrient exchange, and water uptake. These findings provide new insights into AMF adaptive evolution and have implications for sustainable agriculture.

Summary: Invasions by fungal plant pathogens pose a significant threat to agricultural ecosystems. Through population genomics study of Colletotrichum truncatum, a polyphagous and invasive pathogen of soybean in Brazil, it was found that the pathogen is subdivided into three phylogenetically distinct lineages that exchange genetic variation through hybridization. Introgressed regions, which comprise secreted protein-encoding genes, may be the targets of co-evolutionary selection. Population genomic studies can help identify high-risk geographical areas and pathogens, providing valuable information for future crop protection strategies.

This review outlines the interactions between bacteria and fungi in the human body, including their influence on human diseases. The mechanisms and advances in understanding these interactions are discussed, with a focus on three fungal species responsible for systemic fungal infections in humans. The potential of mining microbes for new antimicrobials and antivirulence factors is highlighted.

Summary: This study explores the population structure and genome variation of T. delbrueckii, finding that it is composed of five major clades, with one clade associated with wine fermentation and another with diverse anthropic environments. Comparisons with S. cerevisiae reveal that T. delbrueckii has a smaller variable genome proportion. An association between gene content and ecology supports the hypothesis that the Mix-Anthropic clade has the most specialized genome, with genes implicated in galactose and maltose utilization. Further analyses identify gene clusters associated with dairy products and expanded and functionally diversified genes in strains isolated from bread dough. The study expands our understanding of microbe domestication and adaptation to anthropic niches.

Summary: This study analyzes how a fungal pathogen of barley, Rhynchosporium commune, has adapted to the host environment and fungicide applications. The research shows that gene duplications and deletions are major sources of adaptive genetic variation, with most gene duplications resulting from segmental chromosomal duplications. The pathogen utilizes these adaptive genetic variations to exploit the host and resist fungicides.

Summary: This study investigated the relationship between genetic variation in Arabica coffee and the incidence of four major fungal diseases in southwestern Ethiopia. Results showed that the genetic composition of coffee sites was related to the occurrence of the diseases, but in a specific way for each disease. The findings provide baseline information for studying the molecular basis of disease resistance in coffee.

Summary: This study compares whole genome sequences of Cryptosporidium parvum isolates from human and ruminant hosts collected from different regions globally. It finds evidence of genetic exchanges between different host species and geographic origins, with these exchanges potentially increasing the parasite's virulence. The study suggests that globalization and close human-animal contacts provide opportunities for genetic exchanges between previously isolated parasite lineages, which can impact host-parasite coevolution dynamics.

Summary: Subways are urban transport systems with high passenger capacity. Microbiomes in subways are predominantly composed of skin bacteria and environmental organisms. Bacterial fingerprints of each subway system are determined by low frequency bacteria. Microbial exchange among subway commuters is fast, with hand microbiomes changing within minutes. Despite being harsh environments for microorganism growth, diverse and metabolically active bacteria can be found in subways.

Summary: Human-associated microorganisms are ideal models for studying the effects of environmental changes on species evolution and adaptation. The yeast Brettanomyces bruxellensis is a fascinating organism that has faced anthropogenic-driven selective pressures. In this review, the authors highlight the genetic and phenotypic diversity of this species, which is only beginning to be understood. They discuss the coexistence of different ploidy levels and their association with specific fermented processes, suggesting independent adaptation events to human-modified environments. The authors also emphasize the phenotypic traits of B. bruxellensis and their potential relevance to human activities.

Summary: Plasmids play a key role in bacterial evolution by providing an efficient means for gene sharing among bacterial populations. Network approaches are useful tools for characterizing plasmid-mediated gene sharing events. In the bacterial family Lysobacteraceae, plasmid-mediated adaptation has been reported. Through a comprehensive analysis of bacterial genome sequences, we found that plasmid genes were predominantly shared within the family Lysobacteraceae, with limited exchanges occurring with other families. These sharing events mostly involved a small number of genes and complete plasmid transfers were restricted to closely related taxa. Our findings also revealed multiple plasmid-chromosome gene transfers, including the sharing of heavy metal resistance genes. The network analysis showed that bacterial lifestyles and the presence of specific resistance genes influenced the structure of the network, highlighting the impact of human-mediated selective pressures on pathogenic populations. To better understand how this reservoir contributes to the emergence and spread of genes within the family and its potential impact on plant, animal, and human health, a large-scale sequencing effort on environmental Lysobacteraceae is necessary.

Summary: This study used bibliographic analysis to explore the field of resistance durability in plant protection. It identified three subfields and argues that the split impedes integrated research progress. The study suggests that population genetics can bridge the gap and provide a comprehensive view of pathogen adaptation, particularly through evolutionary-epidemiological feedbacks. Examples are provided to illustrate how this framework can inform best practices for developing and managing genetically resistant cultivars.

Summary: The oral microbiome of Papua New Guineans, especially those living in isolated areas, shows significant geographical variations. Compared to other global populations, Papua New Guineans and Aboriginal Australians have higher abundance of bacterial genera related to iron absorption, suggesting a shared oral microbiome signature. Further studies are needed to confirm and explore this regional-specific oral microbiome profile.

Summary: By investigating the genetic and phenotypic relationship between rice landraces and their rice blast pathogen in traditional flooded rice paddies, it was found that specific lineages of rice blast coexisted in the Yuanyang terraces. The study suggests that disease control strategies based on the emergence or maintenance of a generalist lifestyle in pathogens may sustainably reduce the burden of disease in crops.
