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 …

We have developed a non-radioactive in situ hybridization technique for the localization of
RNA in whole mount Drosophila embryos. After fixation, whole embryos are hybridized in …

A repetitive DNA sequence has been identified in the Drosophila melanogaster genome that
appears to be localized specifically within genes of the bithorax and Antennapedia …

The homeotic genes of the bithorax complex (BX-C) and the Antennapedia complex (ANT-
C) of Drosophila appear to specify the developmental fate of segments or parts of segments …

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 …

Genes that regulate the development of the fruit fly Drosophila melanogaster exist as tightly
linked clusters in at least two cases. These clusters, the bithorax complex (BX-C) and the …

A novel gene of the calmodulin superfamily, encoding a 29-kD neuronal protein here
named" calretinin," has been isolated as a cDNA clone from chick retina. The encoded …

The body plan of Drosophila is determined to a large extent by homeotic genes, which
specify the identity and spatial arrangement of the body segments. Homeotic genes share a …

Summary engrailed is a homeobox gene that has an important role in Drosophila
segmentation. Genes homologous to engrailed have been identified in several other …
