Collective mechanics of embryogenesis: Formation of ventral furrow in Drosophila [PDF]

open access: yesarXiv, 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,

Anchored phylogenomics and revised classification of the Miltogramminae (Diptera: Sarcophagidae)

open access: yesSystematic Entomology, Volume 49, Issue 1, Page 138-155, January 2024.
Anchored hybrid enrichment facilitates the creation of a highly supported phylogenetic hypothesis for the Miltogramminae containing 60% of the currently recognised genera from all biogeographic regions except the Neotropical. The new phylogeny tree facilitates a complete revision of the subfamily including the synonymisation of several genera ...

A Systematic Review of Insect Decline and Discovery: Trends, Drivers, and Conservation Strategies over the past Two Decades

open access: yesPsyche: A Journal of Entomology, Volume 2024, Issue 1, 2024.
Insects make up 75%–80% of all known animal species, with estimates ranging from 10 to 30 million, of which approximately 1.11–1.7 million are described. Despite varying estimates, 80% of insect species remain undiscovered. Unfortunately, insect populations have been declining globally in recent decades, which have significant implications for the ...

Multigenome DNA sequence conservation identifies Hox cis-regulatory elements [PDF]

open access: yes, 2008
To learn how well ungapped sequence comparisons of multiple species can predict cis-regulatory elements in Caenorhabditis elegans, we made such predictions across the large, complex ceh-13/lin-39 locus and tested them transgenically. We also examined how

Population genomics on the fly: recent advances in Drosophila [PDF]

open access: yesarXiv, 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]

open access: yesIEEE 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]

open access: yes, 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).

DrosOCB: a high resolution map of conserved non coding sequences in Drosophila [PDF]

open access: yesarXiv, 2007
Comparative genomics methods are widely used to aid the functional annotation of non coding DNA regions. However, aligning non coding sequences requires new algorithms and strategies, in order to take into account extensive rearrangements and turnover during evolution.
