Behaviors of nucleus, basal bodies and microtubules during eupyrene and apyrene spermiogenesis in the silkworm, Bombyx mori (Lepidoptera)
Year: 1997
Type: article
Abstract: Observations with immunostaining for tubulin and electron microscopy revealed that silkworm eupyrene spermiogenesis was characterized by an attachment of the basal body to the nucleus except in the period of movement for unidirectional arrangement. In young eupyrene sperm, a microtubule basket caught the nucleus, which thereafter was transformed elliptically. Microtubules were also observed along the elongated acrosome and mitochondrial derivatives. During apyrene spermiogenesis, however, the basal body was not attached to the nucleus and approached the head cyst cell after the completion of unidirectional arrangement, leaving the round nucleus in the middle of the cell. The presence or absence of the phenomenon in which the basal body attaches to the nucleus seems to be essential in the course of diverse spermatogenesis of the silkworm.
