Juncus is the largest genus of Juncaceae and was considered holocentric for a long time.
Recent findings, however, indicated that 11 species from different clades of the genus have …

Background/Objectives: Arachnids are a megadiverse arthropod group. The present study
investigated the chromosomes of pedipalpid tetrapulmonates (orders Amblypygi …

Spider diversity is partitioned into three primary clades, namely Mesothelae,
Mygalomorphae, and Araneomorphae. Mygalomorph cytogenetics is largely unknown. Our …

Despite most of the cytogenetic research is focused on monocentric chromosomes,
chromosomes with kinetochoric activity localized in a single centromere, several studies …

Palpigradi are a poorly understood group of delicate arachnids, often found in caves or other
subterranean habitats. Concomitantly, they have been neglected from a phylogenetic point …

Background Holocentric chromosomes occur in approximately 750 species of eukaryotes.
Among them, the genus Tityus (Scorpiones, Buthidae) has a labile karyotype that shows …

In terms of cytogenetics, entelegyne araneomorphs are the best studied clade of spiders.
The typical karyotype of entelegyne males consists of acrocentric chromosomes, including 2 …

A characteristic feature of spider karyotypes is the predominance of unusual multiple X
chromosomes. To elucidate the evolution of spider sex chromosomes, their meiotic behavior …

Palpigradi comprises the most poorly known order within the Arachnida; hence, information
regarding their biology and behavior is quite scarce. We document an interaction between a …

Holocentric chromosomes are characterised by the presence of kinetochoric activity along
the chromosome length. This atypical chromosomal architecture has evolved independently …
