Animal embryos need to specify different cell types, and the genetic functions that provide
such controls are easy to comprehend since they result in the formation of overtly …

Hox genes encode a family of transcriptional regulators that elicit distinct developmental
programmes along the head-to-tail axis of animals. The specific regional functions of …

"... but our knowledge is so weak that no philosopher will ever be able to completely explore
the nature of even a fly..."* Thomas Aquinas" In Symbolum Apostolorum" 079 RSV p/96 This …

We have isolated the Drosophila melanogaster homolog (Dint-l) of in&l, a conserved cellular
oncogene implicated in viral mammary tumorigenesis In mice. The deduced Dint-l protein …

The majority of the genome in animals and plants is transcribed in a developmentally
regulated manner to produce large numbers of non–protein-coding RNAs (ncRNAs), whose …

We characterized the distribution of AGAMOUS (AG) RNA during early flower development
in Arabidopsis. Mutations in this homeotic gene cause the transformation of stamens to …

The vasa gene product of Drosophila melanogaster is required only in the female germ line.
Progeny of females homozygous for vasa mutations lack posterior structures and pole cells …

The metameric organization of the Drosophila embryo is generated in the first 5 h after
fertilization. An initially rather simple pattern provides the foundation for subsequent …

In recent years researchers have analyzed the expression patterns of the Hox genes in a
multitude of arthropod species, with the hope of understanding the mechanisms at work in …

The term" homeosis"(originally spelled" homoeosis") was proposed by Bateson (8) to
describe the transformation of one structure of the body into the homologous structure of …
