We named this phenomenon 'peristaltic squeezing'. Microscopic observation revealed that the elimination of eupyrene nuclei by peristaltic squeezing caused the sterility of polyploids.

The nuclei were discarded from the posterior end by peristaltic squeezing. The circulating fluids were delivered to, and removed from, the treatment vessels by peristaltic pumps regulated by timers. Peristaltic waves may be useful in dispersing the absorbed nutrients among the developing daughter sporocysts or cercariae within. The peristaltic squeezing occurred in the pupae that received the heat treatment. It seems amazing that the silkworm has established a crisis management system in spermatogenesis by adopting such a simple mechanism as peristaltic squeezing. In this study, we compared eupyrene spermatogenesis of the triploid silkworm with that of the diploid and discuss the role of peristaltic squeezing in reproduction. The nuclei that maintained a round shape were discarded from the bundle by peristaltic squeezing. |
