Detailed Description
Statement
Reference

Germline stem cells (GSCs) in newly eclosed par-1k06323/par-1k05603 males show a high frequency of centrosome misorientation and frequently undergo mitosis with misoriented spindles (mitosis with misoriented spindles is not seen in wild-type male GSCs).

par-1k05603/+ mutants exhibit ethanol-induced hyperactivity comparable to wild type.

Embryos derived from par-1k06323/par-1k05603 females have an average of 19 pole cells/embryo (compared to 33 in the wild-type), and 12% of the embryos lack a germline.

20% of embryos derived from par-1k05603/par-1k06323 females die, showing defects which range from disturbances in posterior patterning to complete absence of abdominal segments.

One copy of par-1k05603 partially suppresses the adult mushroom body morphology defects seen in TaoEP1455. Approximately half of all brain hemispheres have fully formed mushroom body lobes.

One copy of par-1k05603 suppresses the reduction in ethanol-induced hyperactivity seen in TaoEP1455 hemizygotes.

Embryos derived from par-1k06323/par-1k05603 ; osk1/+ females have an average of 3 pole cells/embryo (compared to 33 in the wild-type), and 42% of the embryos lack a germline.
