Comment:

A 59 bp deletion which causes a frameshift in Tudor-SN starting at codon Ile437. The deletion extends from +3009 (A) to +3067 (G) relative to the Tudor-SN transcription start.

Detailed Description

Statement

Reference

Tudor-SN¹¹²⁰/Df(3L)BSC125 (2-day old males) have swollen apical tips of testes containing excessive numbers of early spermatogenic cells (86% show this phenotype). Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ (81%) or Tudor-SN¹¹²⁰/Tudor-SN¹²³⁶ (78%) transheterozygotes show the same phenotype. Ovaries appear normal in Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ females.

Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ show an over-proliferation of cells (likely spermatocytes) in the swollen apical tip of testes; a few bundles of mislocalized elongated spermatids with heads residing at the apical tip of the testis are also present (62% display this phenotype). Germline stem cell number is similar to wild type. Mutant third instar larval testes have a higher mitotic index of spermatogonia and are larger than wild type larval testes. In Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ mutant testes, round onion stage spermatids containing a single over-sized Nebenkern associated with two haploid nuclei are observed; 2 week old mutant adult testes have fewer spermatid bundles compared to wild type. Overall, mutant testes have higher proliferation of spermatogonia but compromised differentiation of spermatocytes.

Additional Comments

Genetic Interactions

Statement

Reference

piwi¹/+ (or even more so, piwi¹/piwi²) significantly partially suppresses the swollen apical tip of the testis phenotype seen in Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ males. piwi¹/piwi² suppresses infertility seen in Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ males. Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ partially suppresses ovary defects in piwi¹/piwi² females. Expression of piwi^GD11827 driven in the germline by Scer\GAL4^{nos.UTR.T:Hsim\VP16} (but not Scer\GAL4^tj-NP1624) suppresses the testis swollen apical tip phenotype seen in Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ males.

Complementation and Rescue Data

Partially rescued by

Tudor-SN⁰⁶¹⁴/Tudor-SN¹¹²⁰ is partially rescued by Scer\GAL4^{VP16.nanos.UTR}/Tudor-SN^UAS.Tag:FLAG

(Ku et al., 2016)

Comments

Expression of Tudor-SN^{Scer\UAS.T:Zzzz\FLAG} driven by Scer\GAL4^{nos.UTR.T:Hsim\VP16} partially rescues the swollen testis apical tip phenotype and reduced fertility of Tudor-SN¹¹²⁰/Tudor-SN⁰⁶¹⁴ males.
