Abstract Polycomb group (PcG) and Trithorax group (TrxG) genes encode important
regulators of development and differentiation in metazoans. These two groups of genes …

Chromatin is important for the regulation of transcription and other functions, yet the diversity
of chromatin composition and the distribution along chromosomes are still poorly …

Background Mutations in genes encoding ribosomal proteins (RPs) have been shown to
cause an array of cellular and developmental defects in a variety of organisms. In …

In development, cells pass on established gene expression patterns to daughter cells over
multiple rounds of cell division. The cellular memory of the gene expression state is termed …

Benzene, toluene, ethylbenzene and xylene, also known as BTEX, are released into
environmental media by petroleum product exploratory and exploitative activities and are …

Regenerating tissue must replace lost structures with cells of the proper identity and
function. How regenerating tissue establishes or maintains correct cell fates during regrowth …

The trithorax group genes are required for positive regulation of homeotic gene function. The
trithorax group gene brahma encodes a SWI2/SNF2 family ATPase that is a catalytic subunit …

Abstract Genes of the Drosophila Polycomb and trithorax groups (PcG and trxG,
respectively) influence gene expression by modulating chromatin structure. Segmental …

The polyhomeotic (ph) gene is a member of the Polycomb group of genes (Pc-G), which are
required for the maintenance of the spatial expression pattern of homeotic genes. In contrast …

Abstract The Minute syndrome in Drosophila melanogaster is characterized by delayed
development, poor fertility, and short slender bristles. Many Minute loci correspond to …
