tor mutant that carries alanines in lieu of the degron motif (to disrupt interaction with gcl).
Amino acids IENIG (649-653 in tor-PA) were mutated to a series of alanines (IENIG>5A).

decreased cell number | embryonic stage (with tor2)
primordial germ cell | embryonic stage (with tor2)
Embryos from torDeg/tor2 transheterozygous mothers display a severe failure in primordial germ cell formation, as compared to controls.
