Spoink, a LTR retrotransposon, invaded D. melanogaster populations in the 1990s

R. Pianezza, A. Scarpa, P. Narayanan, S. Signor, R. Kofler

The paper identifies Spoink, a LTR retrotransposon that invaded D. melanogaster populations between 1983 and 1993, likely via horizontal transfer from D. willistoni, and shows it is often silenced by the piRNA pathway.

Evolution of Plasticity in Response to Ethanol between Recently Separated Populations of D. melanogaster with Different Ecological Histories

G. Sarfo-Boateng, F. Scherping-Bustos, M. Mammadov, S. Signor

This study shows that ethanol resistance evolved through genetic accommodation in a French D. melanogaster population, while a Zambian population remained unadapted, supporting the theory of plasticity evolution.

Sex-biased expression is associated with chromatin state in D. melanogaster and D. simulans

A. V. Nanni, N. Martinez, R. Graze, J. R. B. Newman, V. Jain, S. Vlaho, S. Signor, S. V. Nuzhdin, R. Renne, L. McIntyre

The paper investigates the association between chromatin state and sex-biased gene expression in D. melanogaster and D. simulans, finding conserved patterns and species-specific differences.

Rapid evolutionary diversification of the flamenco locus in the D. simulans clade

S. Signor, J. Vedanayagam, B. Y. Kim, F. Wierzbicki, R. Kofler, E. C. Lai

The paper examines the rapid evolutionary changes in the flamenco locus across Drosophila simulans clade species, revealing sequence divergence, copy number variation, and functional adaptations related to transposable element suppression.

Evolutionary dynamics of piRNA clusters in Drosophila

F. Wierzbicki, R. Kofler, S. Signor

This study quantifies the evolutionary dynamics of piRNA clusters in Drosophila, showing rapid divergence and TE-driven changes across species.

Evolution of phenotypic plasticity in response to ethanol between sister species with different ecological histories (Drosophila melanogaster and D. simulans)

S. Signor

The paper examines how phenotypic plasticity contributes to adaptation to ethanol in Drosophila species, finding evidence for genetic accommodation and the role of alternative splicing.

Population genomics of Wolbachia and mtDNA in Drosophila simulans from California

S. Signor

The paper examines the short-term evolution of Wolbachia and mtDNA in Drosophila simulans, finding reduced diversity and a recent selective sweep in mtDNA.
