Fig. 3. retn female behaviors. (A) retn female resistance to male
courtship increases with allelic strength. (1) Wild type (Canton-S) (CS), (2)
retndri2/+, (3) retnRU50/+, (4)
retnz2-428/+, (5)
retnz2-428/retnRU50, (6)
retnRU50/retndri2, (7)
retnz2-428/retndri2. Average time of
courtship prior to copulation for 20 females per genotype is shown. Error bars
indicate s.e.m. Resistance behavior to a maximum of 1 hour was measured.
Wild-type females (1), and retndri2/+ (2),
retnRU50/+ (3) and retnz2-428/+
females (4) copulate in 2-4 minutes (P>0.05 relative to wild
type). retnRU50/retnz2-428 females (5)
average 8.8 minutes (P=0.013).
retnRU50/retndri2 females (6) average
34 minutes (P=5 x10-5), and
retnz2-428/retndri2 (7) females
average 58 minutes (P=5 x10-17). (B) retn
cDNA rescues female resistance behavior. (1) Wild type (CS), (2)
retn-Gal489/retnRU50; +/+, (3)
retn-Gal489/retnRU50;
UAS-retn/+.
retn-Gal489/retnRU50; +/+ females
resist courtship for an average of 25 minutes (P=4
x10-5 relative to wild type).
retn-Gal489/retnRU50;
UAS-retn/+ females copulate in 4.8 minutes (P=3
x10-4 compared with mutant without construct), comparable
with wild type (P=0.077). (C) Courtship chain of retn
(retnz2-428/retndri8) females (arrow).
(D) Female wing extension performed at another female (arrow). Additional
chaining can be seen towards the right (arrowhead). (E) Female (arrow) extends
wing at courting male. (F) Bisexual behavior is increased in retn
females. (1) retnz2-428/+, (2)
retnz2-428/retndri8, (3)
retndri8/+. retndri8/+ and
retnz2-428/+ females average fewer than three
courtship-like behaviors per observation period.
retnz2-428/retndri8 females average
42±7 courtship events (P=0.0001 relative to controls). (G,H)
retnz2-428/retndri8;
fru4-40/fruAJ96u3 females generate
male-like courtship, including both following behavior and wing extension.
