The influence of epoxomicin, inhibitor of proteasomal proteolytic activity, on spermiogenesis in Chara vulgaris.

open access: yesFolia histochemica et cytobiologica, 2003
The influence of 48-h treatment with epoxomicin, an inhibitor of proteolytic activity of proteasomes, at the concentration 10 microM, on spermiogenesis in algae Chara vulgaris was examined. In the presence of the inhibitor, the frequency of early spermiogenesis phases significantly increased, the number of spermatids in mid-phases decreased and ...

Changes in ultrastructure of cytoplasm and nucleus during spermiogenesis in Chara vulgaris.

open access: yesFolia histochemica et cytobiologica, 1996
In the present study much attention was paid to the first and middle stages of spermiogenesis in Chara vulgaris. The spermiogenesis was divided into 8 phases (A-H). In telophase leading to spermatid formation (A phase) there are no structural changes, indicating that cells pass into a new functional stage-spermiogenesis.B phase: After the formation of ...
