The evolutionarily conserved role of Sp1 in appendage morphogenesis

Despite millions of years of independent evolution, some aspects of vertebrate and arthropod development share striking similarities. For example the appendages of a mouse and of a fly, at the naked eye doesn’t seem to share too

Big tasks for small flies: signaling cascades may help insects to detect faint odor traces

Have you ever wondered how a tiny vinegar fly manages to find its way to a ripened fruit in your kitchen? As many other insects flies possess a very keen sense of smell, which allows them to

Different morphs for different seasons: Seasonality of an insect invader

The Spotted Wing Drosophila (SWD), a cousin of the widely-studied model organism Drosophila melanogaster, is a devastating pest of fruit crops such as strawberries, cherries, blueberries, and blackberries.  SWD females lay their eggs inside of fresh fruit,

Prox-1 and adipogenesis

Adipogenesis is the biological process that controls adipocytes differentiation and is one of the most well studied models of cellular differentiation. Adipose tissue is involved in the control of energy balance and especially in the study of

Fertility of Drosophila offspring depends on the correct choice of bridegroom

The cause of offspring sterility of some pairs of Drosophila melanogaster fruit flies is the genetic incompatibility of the parents. The infertility of progeny (mainly of intraspecies hybrid daughters) in such cases occurs only in one cross-direction.

Conditional mutations in drosophila

In 1865, Gregor Mendel discovered the laws of inheritance for the traits of living organisms. Reproduction, the major property of living matter and mode of its existence in the Universe, found itself in the spotlight of biology.
