Detailed Description
Statement
Reference

Mutant flies have electroretinogram defects, although the decline in light response is slower than that seen for strong trp alleles (60% deactivation time for trp14 flies is 5.2 +/- 1.6 seconds compared to 1.5 +/- 0.2 seconds for trp9 flies).

Mutant flies show light-dependent degeneration of rhabdomeres; when maintained under a 12 hour light-12 hour dark cycle rhabdomeres begin to disappear between 7-10 days after eclosion, and almost no rhabdomeres remain after 14 days. In contrast, when maintained in the dark, the number of rhabdomeres per ommatidium does not decrease, even 30 days after eclosion, and the rhabdomeres are normal in size in 30 day old mutant flies.

Additional Comments
Genetic Interactions
Statement
Reference

trpl302 ; trp14 flies show a electroretinogram response in response to a 10 second pulse of light that is similar to that seen in trp14 single mutants.

The retinal degeneration seen in both CalxB and trp14 single mutant flies when they are maintained under a 12 hour light-12 hour dark cycle is suppressed in CalxB trp14 double mutants; most ommatidia in the double mutants contain the normal number of rhabdomeres at 14 days after eclosion.

Arr25 partially suppresses the retinal degeneration seen in trp14 single mutant flies when they are maintained under a 12 hour light-12 hour dark cycle; the double mutants contain the normal number of rhabdomeres at 14 days after eclosion, although the size of the rhabdomeres is reduced compared to controls.
