Structural instability and concerted evolution in the mitochondrial control region of the grey‐headed lapwing Vanellus cinereus during range expansion

Journal of Avian Biology
Mitochondrial genome duplications, particularly within the control region, can influence evolutionary trajectories and population structure, yet their prevalence and dynamics in birds remain insufficiently understood.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The sex determination gene shows no founder effect in the giant honey bee, Apis dorsata.

, 2012
BACKGROUND: All honey bee species (Apis spp) share the same sex determination mechanism using the complementary sex determination (csd) gene. Only individuals heterogeneous at the csd allele develop into females, and the homozygous develop into diploid ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Innovation in founder-run firms: evidence from S&P 500

, 2014
One important element of a firm’s organizational environment that may influence innovation is whether the CEO of the firm is its founder. Popular perception is that the inherent venturous spirit of the founders creates an environment that fosters ...

Genetic evidence points to distinct paternal settlers of the Faroe Islands and Iceland

Frontiers in Genetics
IntroductionThe Faroe Islands are a small archipelago located in the North Atlantic likely colonized by a small group of founders sometime between 50 and 300 CE.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Y-chromosome degeneration due to speciation and founder effect [PDF]

The Y chromosome in the XY sex-determination system is often shorter than its X counterpart, a condition attributed to degeneration after Y recombination ceases.

Genetic variation and founder effects in the parasitoid wasp, Diaeretiella rapae (M'intosh) (Hymenoptera: Braconidae: Aphidiidae), affecting its potential as a biological control agent

, 2003
The effects of recent colonization on the aphid parasitoid, Diaeretiella rapae (M'Intosh) (Hymenoptera: Braconidae: Aphidiidae), in Western Australia were investigated.
