Electrical sound responses of Johnston's organ neurons are virtually abolished in Dnah3MB05004 mutant flies. Mechanical amplification is excessive compared to controls.
Dnah3MB05004 has abnormal auditory perception phenotype, non-suppressible by nandy5
Dnah3MB05004 is a suppressor | partially of abnormal auditory perception phenotype of nandy5
Dnah3MB05004 is a suppressor of abnormal auditory perception phenotype of iavK1
As in either mutant alone, nandy5 Dnah3MB05004 double mutants entirely lack sound-evoked electrical potentials. Mechanical amplification is excessive in the double mutants, similar to Dnah3MB05004 mutants, substantially lower than in nandy5 mutants alone.
No gross morphological defects are seen in the Johnston's organ neurons in Dnah3MB05004 mutant flies and the outer dynein arms in the proximal region of the cilium persist and seem structurally uncompromised.
Sperm from Dnah3MB05004/Df(3L)BSC371 mutant males shows a significant reduction in sperm competition compared with controls.
Dnah3MB05004 is rescued by Dnah3+tWT
Expression of Dnah3+tWT rescues the sound-evoked electrical and mechanical response defects seen in Dnah3MB05004 mutant flies.
Separable from: a secondary uncharacterised mutation that causes male fertility and sperm motility defects.
Precise excision of the Mi{ET1}Dnah3MB05004 element restores the sound-evoked electrical and mechanical response defects seen in Dnah3MB05004 mutant flies.
