Detailed Description
Statement
Reference

Terminal tracheal cells mutant for Syx7brd1615 display branching and lumen defects. Early endosomes are largely absent from Syx7brd1615 mutant terminal cells.

Syx7brd1615 mutants exhibit a variable tracheal terminal cell multi-convoluted lumen defect. They exhibit a moderate pruning defect.

Reference

Terminal tracheal cells that are homozygous mutant for both crb11A22 and Syx7brd1615 are almost completely rescued for cysts, although, defects in branch number are enhanced as compared to Syx7brd1615 alone.

Heterozygosity for MoeG0323 dramatically rescues the Syx7brd1615 terminal tracheal cell defects. The number of cysts is reduced, and terminal branching is greatly restored. The early endocytosis defects of Syx7brd1615 are not rescued by heterozygous MoeG0323.
