      Normal looking individualisation complexes (ICs) are seen in the testes of X/kl-328 males. Spermatid tails show irregularities.

      (Timakov and Zhang, 2000)

      Male sterile in combination with Ts(1Lt;YSt)W27, Ts(1Lt;YSt)E15 or Ts(1Lt;YSt)F12. Male fertile in combination with Ts(1Lt;YSt)V24, Ts(1Lt;YLt)V8 or Ts(1Lt;YLt)W19. kl-328 testes show degradation in the basal testicular region. Sperm are absent from the seminal vesicles. Postmeiotic nuclei show almost normal nuclear condensation, except for the appearance of occasional singular needle-shaped nuclear heads. The organised bundles of the elongated sperm heads are eventually disintegrated in the basal region of the testis before the spermatids reach maturity. Defects are seen in the flagellar axoneme; the outer arm dyneins are lost of greatly reduced. Abnormal, discontinuous cellular membrane structures are seen in spermatid tails at the postelongation stage.

      Male sterile phenotype can be reverted in the presence of a transposase source.
