| March 2022 |
|
|
Paper accepted: On the first day of spring, our study on the mechanism of parental RNAi in Tribolium debuts in the new journal Advanced Genetics. This tripartite study shows that long dsRNA originally injected into the mother is directly transmitted into eggs, and yet -- without dsRNA amplification -- strain-specific knockdown can last for months. Furthermore, phylogenomic profiling reveals multiple losses of the dsRNA importer SID-1 from arthropod genomes, notably including the true bugs (Heteroptera).

Paper accepted: Danka's beautifully detailed investigation of functional divergence of the Tribolium zen paralogues is accepted for publication in Communications Biology (currently available on bioRxiv). By integrating diverse gene expression and functional data, we demonstrate that the evolutionary acquisition of reciprocal paralogue regulation promotes developmental progression and may have underpinned multiple ancestral subfunctionalization events. Long-term expression profiling also informs the transcriptional landscape of late beetle embryogenesis and characterizes physiological processes in the serosal epithelium.
