...Joanna Krzemień; Caroline C. G. Fabre; José Casal; Peter A. Lawrence In the past, segments were defined by landmarks such as muscle attachments, notably by Snodgrass, the king of insect anatomists. Here, we show how an objective definition of a segment, based on developmental compartments, can help...

.... We then searched for the engrailed -dependent agent responsible for these repellent properties. We found slit to be expressed in the P compartment and, using genetic mosaics, present evidence that Slit is the responsible molecule. Blocking the activity of the three Robo genes (putative receptors...

... , the developmental and growth parameters of which are well known. We have devised a method to generate entire fast-growing Minute + (M + ) discs or compartments in slow developing Minute/+ (M/+) larvae. Under these conditions, a M + wing disc gains at least 20 hours of additional development time. Yet it grows...

... Hedgehog and Decapentapelagic, but not Wingless, signaling. Additionally, squamous morphogenesis shifts the anteroposterior (AP) compartment boundary in the peripodial epithelium relative to the stationary AP boundary in the disc proper. Finally, by lineage tracing cells in the PE, we surprisingly find...

... to later neural subdivisions initially formed overlapping populations, but after stage 16+ they formed non-overlapping cell groups having characteristics of tissue `compartments', preceding development of morphologically distinct neural subdivisions. In early retinal development, a single compartment...

... that anterior and posterior somite domains are not lineage-restricted compartments with respect to distribution along the anteroposterior axis but support a ‘leaky’ resegmentation in development from somite to vertebral column. Alignment of somites with vertebrae suggests that the first two somites do...

...Myriam Zecca; Gary Struhl Growth and patterning of the Drosophila wing imaginal disc depends on its subdivision into dorsoventral (DV) compartments and limb (wing) and body wall (notum) primordia. We present evidence that both the DV and wing-notum subdivisions are specified by activation...

...Peter A. Lawrence; José Casal; Gary Struhl ABSTRACT Like the Drosophila embryo, the abdomen of the adult consists of alternating anterior (A) and posterior (P) compartments. However the wing is made by only part of one A and part of one P compartment. The abdomen therefore offers an opportunity...

...Peter A. Lawrence1; José Casal; Gary Struhl ABSTRACT The adult abdomen of Drosophila is a chain of anterior (A) and posterior (P) compartments. The engrailed gene is active in all P compartments and selects the P state. Hedgehog enters each A compartment across both its anterior and posterior edges...

.... Here we provide evidence that each primordium is divided into anterior and posterior compartments. Genes that are known to be expressed in compartment-specific manners in other discs ( engrailed, hedgehog, patched, decapentaplegic, wingless and cubitus interruptus ) are expressed in analogous patterns...

...Eric Birgbauer; Scott E. Fraser ABSTRACT Previous cell lineage studies indicate that the repeated neuromeres of the chick hindbrain, the rhombomeres, are cell lineage restriction compartments. We have extended these results and tested if the restrictions are absolute. Two different cell marking...

...Seth S. Blair ABSTRACT The dorsoventral (D/V) lineage boundary in the developing wing disc of Drosophila restricts growing cells to the prospective dorsal or ventral compartments of the wing blade. This restriction appears along the prospective margin of the wing some time during the middle to late...

...Stephen J. Poole; Thomas B. Kornberg ABSTRACT The engrailed gene is required for segmentation of the Drosophila embryo and is expressed in cells constituting the posterior developmental compartments. In mutant embryos lacking engrailed function, portions of the cuticular pattern in each segment...
