Evolution of the sugar receptors in insects

open access: yesBMC Evolutionary Biology, 2009
Background Perception of sugars is an invaluable ability for insects which often derive quickly accessible energy from these molecules. A distinctive subfamily of eight proteins within the gustatory receptor (Gr) family has been identified as sugar ...

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 ...

The Drosophila melanogaster Muc68E Mucin Gene Influences Adult Size, Starvation Tolerance, and Cold Recovery

open access: yesG3: Genes, Genomes, Genetics, 2016
Mucins have been implicated in many different biological processes, such as protection from mechanical damage, microorganisms, and toxic molecules, as well as providing a luminal scaffold during development.

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 ...

Inferring genome-scale rearrangement phylogeny and ancestral gene order: a Drosophila case study [PDF]

open access: yes, 2007
A simple, fast, and biologically-inspired computational approach to infer genome-scale rearrangement phylogeny and ancestral gene order has been developed and applied to eight Drosophila genomes, providing insights into evolutionary chromosomal ...

Parametric Alignment of Drosophila Genomes [PDF]

open access: yes, 2005
The classic algorithms of Needleman--Wunsch and Smith--Waterman find a maximum a posteriori probability alignment for a pair hidden Markov model (PHMM). In order to process large genomes that have undergone complex genome rearrangements, almost all existing whole genome alignment methods apply fast heuristics to divide genomes into small pieces which ...

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 ...

Evolution and potential function of fibrinogen-like domains across twelve Drosophila species [PDF]

open access: yes, 2008
Background The fibrinogen-like (FBG) domain consists of approximately 200 amino acid residues, which has high sequence similarity to the C-terminal halves of fibrinogen β and γ chains.

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.

A new Amazonian species from the Drosophila annulimana species group (Diptera, Drosophilidae) Uma nova espécie amazônica pertencente ao grupo de espécies Drosophila annulimana (Diptera, Drosophilidae)

open access: yesRevista Brasileira de Entomologia, 2012
Drosophila caxiuana sp. nov., Drosophila subgenus, is described and illustrated. This new species was collected in the Amazonian Biome (Caquajó river, Portel, Pará, Brazil) and is an atypical species to the group due the unusual morphology of the male ...
