The relationship between microtubules and chromatin in spermatids ofAcrididae

A frequent coincidence of perinuclear microtubules and chromatin strands at nuclear membrane level was observed in spermatids ofChorthippus apicalis andOedipoda coerulescens. More developed spermatids also show apparent continuity between these chromatin strands and microtubules. We would suggest the importance of this relationship in the arrangement adopted by these strands.
