... of this organ. foi is also required for tracheal branch fusion during tracheal development. E-cadherin/shotgun is similarly required for both gonad coalescence and tracheal branch fusion, suggesting that E-cadherin and FOI cooperate to mediate these processes. foi encodes a member of a novel family...

... of these homeotic genes, the expression of unp expands more posteriorly to the abdominal segments. This is consistent with the notion that Ubx controls tracheal development by regulating the expression of target genes ( Lewis, 1978 ). Since unp encodes a transcription factor and is required for cerebral...

... and are in direct contact with the target tissues. The DSRF gene was mapped to position 60C on the second chromosome, and overlapping deficiencies which remove the gene were identified. Analysis of tracheal development in embryos carrying these deletions revealed a degeneration of most of the major branches...
