Gene loss propensity for metallocarboxypeptidase E in insects is shaped by structural versatility and broader expression of metallocarboxypeptidase D but not functional importance

Christian Wegener, Julian C. Heitkamp, Vera S. Hunnekuhl

Abstract Gene loss is a widespread phenomenon that shapes genome evolution, yet the factors determining why certain genes are repeatedly lost while other functionally related genes are retained remain poorly understood. We addressed this question using the peptide-processing metallocarboxypeptidases carboxypeptidase E (CPE) …

Behavioural and neurogenetic evidence for emotion primitives in the fruit fly Drosophila: insights from the Open Field Test

Yi Lueningschroer-Wang, Emilia Derksen, Maria Steigmeier, Christian Wegener

Emotions, defined as transient states preparing organisms for adaptive responses, are thought to be based on evolutionarily conserved building blocks (“emotion primitives”) that are present across mammalian and other vertebrate species. Whether and to which extent these building blocks are found in …

Continent-wide differentiation of fitness traits and patterns of climate adaptation among European populations of Drosophila melanogaster

Esra Durmaz Mitchell, Envel Kerdaffrec, Ewan Harney, Tânia F. Paulo et autres

Abstract A particularly well-studied evolutionary model is the vinegar fly Drosophila melanogaster, a cosmopolitan insect of ancestral southern-central African origin. Recent work suggests that it expanded out of Africa ∼9,000 years ago, and spread from the Middle East into Europe ∼1,800 years …

Triggering and modulation of a complex behavior by a single peptidergic command neuron in Drosophila

Magdalena Fernandez-Acosta, Rebeca Zanini, Fabiana Herédia, Yanel Volonté et autres

larvae remodel their bodies, glue themselves to a substrate, and harden their cuticle in preparation for metamorphosis. This process-termed pupariation-is triggered by a surge in the hormone ecdysone. Substrate attachment is achieved by a pupariation subprogram called glue expulsion and spreading behavior …

Neuronal and endocrine mechanisms underlying the circadian gating of eclosion: insights from Drosophila

Christian Wegener, Emad Amini, Javier Cavieres-Lepe, John Ewer

The circadian rhythm of adult emergence (aka eclosion) of the fruit fly Drosophila is a classic behavioural read-out that served in the first characterisation of the key features of circadian clocks and was also used for the identification of the first clock …

The Alk receptor tyrosine kinase regulates Sparkly, a novel activity regulating neuropeptide precursor in the Drosophila central nervous system

Sanjay Kumar Sukumar, Vimala Antonydhason, Linnea Molander, Jawdat Sandakly et autres

Numerous roles for the Alk receptor tyrosine kinase have been described in Drosophila , including functions in the central nervous system (CNS), however the molecular details are poorly understood. To gain mechanistic insight, we employed Targeted DamID (TaDa) transcriptional profiling to identify …
