Upon the emergence of SARS-CoV-2 in the human population, it was conjectured that for
this coronavirus the dynamic intra-host heterogeneity typical of RNA viruses would be toned …

Adverse environmental factors challenge the existence of every living being. In nature,
sexual reproduction and meiotic recombination act to generate genetic variations that help …

How organisms respond to environmental stress is a key topic in evolutionary biology. This
study focused on the genomic evolution of Laburnicola rhizohalophila, a dark-septate …

Antimicrobial drug resistance poses a global health threat, requiring a deeper
understanding of the evolutionary processes that lead to its emergence in pathogens …

Polyploid organisms are common and can be found across the tree of life. A key question is
to understand how and why these polyploid lineages become established and persist in …

The phytopathogenic fungus Ustilago maydis causes corn smut by suppressing host plant
defenses, including the oxidative burst response. While many studies have investigated how …

Although implicated as deleterious in many organisms, aneuploidy can underlie rapid
phenotypic evolution. However, aneuploidy will only be maintained if the benefit outweighs …

Whole-genome duplication (WGD) is widespread across eukaryotes and can promote
adaptive evolution 1-4. However, given the instability of newly-formed polyploid genomes 5 …

Gene duplication and subsequent amplification can drive adaptation by rapidly increasing
the cellular dosage of critical gene products. Gene duplication events often encompass …

Shifts in environmental conditions can impose strong selection for adaptive traits. During the
Cenozoic era, as the oceans cooled, many marine teleost fish species were at risk of …
