title: Transcriptional changes in pupal hypoderm in Drosophia melanogaster.
abstract: Transcriptional changes with development of the imaginal thoracic hypoderm of Drosophila melanogaster were evaluated by studies on pulse labeling and total composition with respect to protein. Evidence presented indicates that certain glycoproteins produced by prepupal salivary glands are important for bristle development long after the salivary gland is histolyzed. Striking changes in protein synthesis with development can be correlated with major hypodermal functions such as bristle formation, chitin deposition, and a moltlike process which occurs around 52 hr after puparium formation.
