Gene protein sequence evolution can predict the rapid divergence of ovariole numbers in Drosophila

The paper identifies 42 genes linked to ovariole number divergence in Drosophila by analyzing molecular evolution patterns across five species.

oskar acts with the transcription factor Creb to regulate long-term memory in crickets

The paper shows oskar works with Creb to regulate long-term memory in crickets, supporting its evolutionary origin in neural functions.

Phylotranscriptomics reveals discordance in the phylogeny of Hawaiian Drosophila and Scaptomyza (Diptera: Drosophilidae)

The paper uses transcriptomic data to resolve the phylogeny of Hawaiian Drosophila and Scaptomyza, revealing discordance in clade relationships and evolutionary dynamics.

The evolution of ovary-biased gene expression in Hawaiian Drosophila

The paper analyzes RNAseq data from twelve Hawaiian Drosophilidae species to study ovary-biased gene expression evolution, finding stable gene cohorts and significant correlations between interacting genes.

Evolution of a cytoplasmic determinant: evidence for the biochemical basis of functional evolution of a novel germ line regulator

The paper identifies conserved residues in the Oskar protein that may underlie its germ line regulatory function through dimerization and RNA binding.

Evolutionary dynamics of sex-biased genes expressed in cricket brains and gonads

This study examines sex-biased gene expression and protein evolution in cricket brains and gonads, finding accelerated evolution in testis-biased genes and sex-biased brain genes.

Repeated loss of variation in insect ovary morphology highlights the role of developmental constraint in life-history evolution

The paper examines the relationship between egg size and ovariole number in insects, finding a negative correlation that is not universal across all clades and highlighting the role of developmental constraints in shaping life-history traits.

Evidence of multifaceted functions of codon usage in translation within the model beetle Tribolium castaneum

This study investigates codon usage in Tribolium castaneum, revealing tissue-specific and non-optimal codon roles in translation and gene regulation.

Bacterial contribution to genesis of the novel germ line determinant oskar

The paper shows that horizontal gene transfer and de novo gene evolution contributed to the creation of the insect germ line determinant oskar.

Absence of a faster-X effect in beetles (Tribolium, Coleoptera)

This study finds no faster-X effect in beetles, suggesting high constraint on X-linked ovary-biased genes and lack of dosage compensation in testis.

Ancestral and offspring nutrition interact to affect life history traits in Drosophila melanogaster

This study examines how ancestral and offspring nutrition affect life history traits in Drosophila melanogaster across three generations, revealing complex interactions and generational effects on phenotypes.

Insect egg size and shape evolve with ecology, not developmental rate

This study shows that insect egg size and shape evolve based on ecological factors like parasitism and oviposition, not developmental rate or body size.

A database of egg size and shape from more than 6,700 insect species

The paper creates a database of insect egg size and shape data from 6,706 species, enabling evolutionary hypothesis testing.

Reproductive capacity evolves in response to ecology through common developmental mechanisms in Hawaiian Drosophila

This study investigates how reproductive capacity evolves in Hawaiian Drosophila by linking ecological adaptation to developmental mechanisms controlling ovariole number.
