Homeodomain Proteins: Homeotic genes seek partners

Current Biology, 1994
The interactions of one homeodomain protein with another may be a general way in which their specificity is enhanced.

Regulatory mechanisms for floral homeotic gene expression

Seminars in Cell & Developmental Biology, 2010
Proper regulation of floral homeotic gene (or ABCE gene) expression ensures the development of floral organs in the correct number, type, and precise spatial arrangement. This review summarizes recent advances on the regulation of floral homeotic genes, highlighting the variety and the complexity of the regulatory mechanisms involved.

Autoregulation of a drosophila homeotic selector gene

Cell, 1988
The Deformed (Dfd) gene is a homeotic selector that functions in specifying the identity of the mandibular and maxillary segments. We have constructed transformed fly strains carrying a Dfd cDNA under the heat-inducible control of the hsp70 promoter.

Targets of homeotic gene control in Drosophila

Nature, 1990
The homeotic gene Ultrabithorax (Ubx) encodes homeodomain-containing transcription factors that determine segmental identity in Drosophila. Here, an immunopurification procedure is described that enriches for embryonic chromatin fragments containing binding sites for Ubx protein. In two cases these binding sites are located near embryonic transcription

The specificity of homeotic gene function

BioEssays, 1995
AbstractHow transcription factors achieve their in vivo specificities is a fundamental question in biology. For the Homeotic Complex (HOM/Hox) family of homeoproteins, specificity in vivo is likely to be in part determined by subtle differences in the DNA binding properties inherent in these proteins. Some of these differences in DNA binding are due to

Regulation of the arabidopsis floral homeotic gene APETALA1

Cell, 1994
The Arabidopsis floral homeotic gene APETALA1 (AP1) encodes a putative transcription factor that acts locally to specify the identity of the floral meristem and to determine sepal and petal development. RNA tissue in situ hybridization studies show that AP1 RNA accumulates uniformly throughout young floral primordia, but is absent from the ...

The evolution of floral homeotic gene function

BioEssays, 2003
AbstractPlant MADS‐box genes encode transcriptional regulators that are critical for a number of developmental processes. In the angiosperms (the flowering plants), these include the specification of floral organ identities, flowering time and fruit development.

A Polycomb-group gene regulates homeotic gene expression in Arabidopsis

Nature, 1997
Cell fate is determined when the commitment of cells to a particular fate is autonomously maintained, irrespective of their environment. In Drosophila, fate determination is maintained through the action of the Polycomb-group and trithorax-group genes, which are required so that states of homeotic gene activity are inherited through cell division.

[Homeotic genes].

Reproduction, nutrition, development, 1990
Homeotic genes occupy a central position in the hierarchy of genes controlling the early steps of embryonic development in Drosophila. They are involved in the specification of the individual identity of each segment of the insect's body. Most homeotic genes of Drosophila are located in two large gene clusters, the Antennapedia complex (ANT-C) and the ...

Downstream of the homeotic genes.

The New biologist, 1992
The homeotic genes of Drosophila melanogaster determine which structures form in each of the body segments. Disrupting the function of the homeotic genes causes body parts found in one domain of the animal to be replaced by body parts normally found elsewhere.
