Collective mechanics of embryogenesis: Formation of ventral furrow in Drosophila [PDF]
arXiv, 2011 We propose a 2D mechanical model of the ventral furrow formation in Drosophila that is based on undifferentiated epithelial cells of identical properties whose energy resides in their membrane. Depending on the relative tensions of the apical, basal, and lateral sides, the minimal-energy states of the embryo cross-section includes circular, elliptical,

Codon usage in twelve species of \u3ci\u3eDrosophila\u3c/i\u3e [PDF]
, 2007 Background: Codon usage bias (CUB), the uneven use of synonymous codons, is a ubiquitous observation in virtually all organisms examined. The pattern of codon usage is generally similar among closely related species, but differs significantly among ...

Vagaries of the molecular clock [PDF]
, 1997 The hypothesis of the molecular evolutionary clock asserts that informational macromolecules (i.e., proteins and nucleic acids) evolve at rates that are constant through time and for different lineages.

Ribosomal intergenic spacer (IGS) length variation across the Drosophilinae (Diptera: Drosophilidae) [PDF]
, 2005 BACKGROUND: The intergenic spacer of the ribosomal genes in eukaryotes (IGS) contains duplications of the core transcription promoter. The number of these duplicated promoters, as measured by the IGS length, appears to be correlated with growth rate and ...

Population genomics on the fly: recent advances in Drosophila [PDF]
arXiv, 2018 Drosophila melanogaster, a small dipteran of African origin, represents one of the best-studied model organisms. Early work in this system has uniquely shed light on the basic principles of genetics and resulted in a versatile collection of genetic tools that allow to uncover mechanistic links between genotype and phenotype.

Social Behavioral Phenotyping of Drosophila with a2D-3D Hybrid CNN Framework [PDF]
IEEE Access 2019, 2019 Behavioural phenotyping of Drosophila is an important means in biological and medical research to identify genetic, pathologic or psychologic impact on animal behaviour.

A comparative analysis of transcription factor expression during metazoan embryonic development [PDF]
, 2013 During embryonic development, a complex organism is formed from a single starting cell. These processes of growth and differentiation are driven by large transcriptional changes, which are following the expression and activity of transcription factors (TFs).

Phylogeny of the Orangethroat Darter (Etheostoma spectabile) species complex in the Ozark Highlands of Arkansas [PDF]
, 2018 Darters are small, benthic fishes that live in freshwater rivers and streams and belong to the family Percidae. Pleistocene glaciations fragmented many darter species, resulting in speciation, but new species are often hard to detect if they are ...

Multiple and diverse structural changes affect the breakpoint regions of polymorphic inversions across the Drosophila genus [PDF]
, 2017 Chromosomal polymorphism is widespread in the Drosophila genus, with extensive evidence supporting its adaptive character in diverse species. Moreover, inversions are the major contributors to the genus chromosomal evolution.
