Detailed Description

Statement

Reference

β-PheRS³²²/Df(3R)Exel6198 (β-PheRS null) flies rescued with the β-PheRS^A158W mutant construct have no obvious phenotypes, showing normal developmental time, body size and bristle shape.

β-PheRS³²²/Df(3R)Exel6198 (β-PheRS null) flies rescued with the β-PheRS^A158W mutant construct show normal locomotion (climbing) ability over several weeks. Survival rates also drop after 50 days, compared to controls.

Genetic Interactions

Statement

Reference

In β-PheRS³²²/Df(3R)Exel6198 (β-PheRS null) flies rescued with β-PheRS^A158W, Scer\GAL4^ey.PH-mediated expression of α-PheRS^{A456G.Scer\UAS} results in severe disruption of eye organization - most ommatidia are irregular, the entire eye is smaller and the eye surface is rough. The retina and ommatidia lack regular patterns, shapes and organization because of smaller ommatidia and absence of many cells.

Scer\GAL4^Act5C.PI-mediated expression of α-PheRS^{A456G.Scer\UAS} in adults (via use of Scer\GAL80^ts.αTub84B) in a β-PheRS³²²/Df(3R)Exel6198 (β-PheRS null) background rescued with β-PheRS^A158W results in many elav-positive brain (neuronal) cells entering apoptosis.

In β-PheRS³²²/Df(3R)Exel6198 (β-PheRS null) flies rescued with β-PheRS^A158W, Scer\GAL4^en-e16E-mediated expression of α-PheRS^{A456G.Scer\UAS} results in decreased wing size , and in some wings entire regions of the posterior compartment are missing. In wing discs, the number of apoptotic cells is increased, while cell size is either similar or slightly bigger than controls, suggesting that cell number (proliferation) must be reduced.

In β-PheRS³²²/Df(3R)Exel6198 (β-PheRS null) flies rescued with β-PheRS^A158W, Scer\GAL4^ppl.PP-mediated expression of α-PheRS^{A456G.Scer\UAS} results in reduced pupariation rates when larvae are raised on Tyrosine-rich (but not alanine- or phenylalanine-rich or standard) food.
