Polycomb/Trithorax response elements (PRE/TREs) maintain transcriptional decisions to
ensure correct cell identity during development and differentiation. There are thought to be over …

It is broadly accepted that long-term memory (LTM) is formed sequentially after learning and
short-term memory (STM) formation, but the nature of the relationship between early and …

Variegation of the miniwhite gene is observed in a euchromatic context in transformant lines
that contain a P transposon including regulatory sequences of the polyhomeotic (ph) gene …

Conserved Ryk transmembrane proteins, tyrosine kinase-related Wnt receptors, are
important during neurogenesis, axon guidance and synaptogenesis. Here, we review the …

Developmental axon pruning is a general mechanism that is required for maturation of neural
circuits. During Drosophila metamorphosis, the larval-specific dendrites and axons of early …

We describe the identification of linotte, a new autosomal gene in Drosophila involved with
learning and memory. The linotte 1 mutant was dervied from a PlacW transposon …

Wnt Planar Cell Polarity (PCP) signaling is a universal regulator of polarity in epithelial cells,
but it regulates axon outgrowth in neurons, suggesting the existence of axonal modulators …

Two mutagenic events are required to make null mutations of polyhomeotic (ph), which
suggests that the locus is complex. Amorphic mutations (ph) die in mid-embryogenesis and …

Gene silencing by heterochromatin is a well-known phenomenon that, in Drosophila, is
called position effect variegation (PEV). The long-held hypothesis that this gene silencing is …

One of the most dramatic examples of programmed cell death occurs during Drosophila
metamorphosis, when most of the larval tissues are destroyed in a process termed histolysis. …
