General Information
Term tracheal pit formation in open tracheal system ID (Ontology) GO:0035202 (Gene Ontology)
Definition Formation of the tracheal pits, the first tube-like structures to form in the open tracheal system. Once cells are determined to their tracheal cell fate, the tracheal pits arise by invagination of each ectodermal cluster of tracheal placode cells, between 5 and 7 hours after egg laying. An example of this is found in Drosophila melanogaster.[ PubMed:11063940 PubMed:11992723 PubMed:14570584 ]
