Heteropicnotic chromatin and nucleolar activity in meiosis and spermiogenesis of Limnogonus aduncus (Heteroptera, Gerridae): a stained nucleolar organizing region that can serve as a model for studying chromosome behavior.
(2008-12-01)
Males of Limnogonus aduncus were found to have the sex chromosome system X0 and chromosome number 2n = 23 (22A + X0). Testis cells were stained with lacto-acetic orcein and silver nitrate so that changes in the morphology ...

Colocalization of coilin and nucleolar proteins in Cajal body-like structures of micronucleated PtK2 cells
(Associação Brasileira de Divulgação Científica, 2004-07-01)
Cajal bodies (CB) are ubiquitous nuclear structures involved in the biogenesis of small nuclear ribonucleoproteins and show narrow association with the nucleolus. To identify possible relationships between CB and the ...
Pattern of silver nitrate-staining during meiosis and spermiogenesis in testicular lobes of Antiteuchus tripterus (Heteroptera: Pentatomidae)
(2008-04-22)
The pattern of silver nitrate (Ag)-staining differed among testicular lobes of Antiteuchus tripterus. In general, these differences are in regard to the number, size, shape, coloring intensity, and location of the stained ...

Is there post-meiotic transcriptional activity during hemipteran spermiogenesis?
(Taylor & Francis Ltd, 2014-09-01)
Different techniques have been used to evaluate post-meiotic nucleolar activity during spermatogenesis. However, the results have not been consistent, and transcriptional activity during spermiogenesis is still a highly ...
New evidence for nucleolar dominance in hybrids of Drosophila arizonae and Drosophila mulleri
(2006-12-18)
Drosophila mulleri (MU) and D. arizonae (AR) are cryptic species of the mulleri complex, mulleri subgroup, repleta group. Earlier cytogenetic studies revealed that these species have different regulatory mechanisms of ...
