Fig. 4. bchs mutations suppress the lethality of rab11
mutants.Sixty second-instar larvae of each genotype were placed in
identical vials and monitored for survival to adulthood. Df is
Df(2L)cl7, a chromosome deleted for bchs. Data in A and B
represent two independent sets of experiments that were not pooled because the
survival of rab11 mutants varied slightly between them. (A)
bchs mutations reduce lethality of rab11 hypomorphs
(P<0.01 for
Df(2L)cl7/bchs17;rab11ex1/rab1193Bi
vs rab11ex1/rab1193Bi and P<0.0005
for
bchs17/bchs12;rab11ex1/rab1193Bi
vs rab11ex1/rab1193Bi) (n
3
vials/genotype, unpaired t-test). (B) Two-fold reduction in
bchs gene dosage reduces lethality of rab11 hypomorphs.
Compared to rab11ex1/rab1193Bi:
P<0.005 for
Df(2L)cl7/+;rab11ex1/rab1193Bi, P<0.0005 for
bchs17/+;rab11ex1/rab1193Bi and
P<0.01 for
bchs17/bchs12;rab11ex1/rab1193Bi
(n
5 vials/genotype). Error bars are s.e.m.
