Linked Selection and Gene Density Shape Genome‐Wide Patterns of Diversification in Peatmosses

open access: yesEvolutionary Applications, Volume 17, Issue 8, August 2024.
ABSTRACT Genome evolution under speciation is poorly understood in nonmodel and nonvascular plants, such as bryophytes—the largest group of nonvascular land plants. Their genomes are structurally different from angiosperms and likely subjected to stronger linked selection pressure, which may have profound consequences on genome evolution in ...

Evolution of sex‐biased genes in Drosophila species with neo‐sex chromosomes: Potential contribution to reducing the sexual conflict

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
In theory, having sex chromosomes is advantageous to reduce sexual conflict. Our analyses revealed that many genes have acquired the sex‐biased expression on the neo‐sex chromosomes particularly at the larval stage. Our study indicates that cryptic sexual conflict at the preadult stages cannot be ignored, and some of these conflicts may have been ...

Gap‐free X and Y chromosome assemblies of Salix arbutifolia reveal an evolutionary change from male to female heterogamety in willows, without a change in the position of the sex‐determining locus

open access: yesNew Phytologist, Volume 242, Issue 6, Page 2872-2887, June 2024.
Summary In the Vetrix clade of Salix, a genus of woody flowering plants, sex determination involves chromosome 15, but an XY system has changed to a ZW system. We studied the detailed genetic changes involved. We used genome sequencing, with chromosome conformation capture (Hi‐C) and PacBio HiFi reads to assemble chromosome level gap‐free X and Y of ...

Insights into the evolution of herbivory from a leaf‐mining fly

open access: yesEcosphere, Volume 15, Issue 4, April 2024.
Abstract Herbivorous insects and their host plants comprise most known species on Earth. Illuminating how herbivory repeatedly evolved in insects from nonherbivorous lineages is critical to understanding how this biodiversity is created and maintained.

Bacteria and viruses and their role in the preschool wheeze to asthma transition

open access: yesPediatric Allergy and Immunology, Volume 35, Issue 3, March 2024.
Abstract Wheezing is the cardinal symptom of asthma; its presence early in life, mostly caused by viral infections, is a major risk factor for the establishment of persistent or recurrent disease. Early‐life wheezing and asthma exacerbations are triggered by common respiratory viruses, mainly rhinoviruses (RV), and to a lesser extent, respiratory ...
