HtrA2βTub85D.PY is a non-suppressor of sterile phenotype of Pink15
HtrA2βTub85D.PY is a non-suppressor of spermatid phenotype of Pink15
HtrA2βTub85D.PY is a non-suppressor of Nebenkern phenotype of Pink15
HtrA2βTub85D.PY is a non-suppressor of mitochondrial derivative phenotype of Pink15
Expression of HtrA2βTub85D.PY fails to suppress the mitochondrial morphology defects seen in Pink15 mutant spermatids. The spherical "onion stage" nebenkern contain vacuoles, and only one mitochondrial derivative is seen in "leaf blade stage" elongating spermatids. As in Pink15 mutants alone the flies are sterile.
Expression of HtrA2βTub85D.PY rescues the spermatogenesis defects seen in HtrA2NSO/Df(3R)ED5644 mutant males. Motile sperm are present in the seminal vesicles and the individualisation defects are suppressed.
