...P. W. Ingham; A. Hidalgo ABSTRACT The segment polarity gene wingless ( wg ) is expressed in a complex pattern during embryogenesis suggesting that it plays multiple roles in the development of the embryo. The best characterized of these is its role in cell pattening in each parasegment, a process...

...Bernadette Limbourg-Bouchon; Denise Busson; Claudie Lamour-Isnard ABSTRACT Fused (fu) is a segment polarity gene whose product is maternally required in the posterior part of each segment. To define further the role of fused and determine how it interacts with other segmentation genes, we examined...

...Mark Peifer; Cordelia Rauskolb; Michelle Williams; Bob Riggleman; Eric Wieschaus ABSTRACT The segment polarity genes of Drosophila were initially defined as genes required for pattern formation within each embryonic segment. Some of these genes also function to establish the pattern of the adult...
