It was investigated whether (1) the number of cilia of the dorsal kineties 3 and 4 and (2) the cell length are species-specific characters which can be used to distinguish the sibling species S. mytilus and S. lemnae. The number of cilia of the dorsa

A differentiation, based on morphological characters, between Stylonychia mytilus and Stylonychia lemnae is very difficult, especially for non-specialists. These two sibling species were considered as one species, S. mytilus, until detailed cytologic

The macronuclei of the ciliated protozoan Stylonychia lemnae are highly resistant to several DNA-damaging agents, but the micronuclei are sensitive. Possible reasons for these differences were investigated. Although both kinds of nuclei continue to s

The small subunit rDNAs of five species belonging to the Euplotidae and eight species of the Oxytrichidae were sequenced to obtain a more detailed picture of the phylogenetic relationships within the Spirotrichea (Ciliophora). Various tree reconstruc

The origins of DNA replication in prokaryotes and eukaryotes are typically defined by cis-acting sequences. However, in ciliates, evidence suggests that the replication of short macronuclear minichromosomes may not require such determinants. In hypot

Summary Macronuclei of Stylonychia lemnae contain millions of gene sized minichromosomes. These minichromosomes in general harbour only one gene. Their nontranscribed regions are usually less than 400 bp long and most likely carry the signals for DNA

The blepharismins ( 1 ) from Blepharisma japonicum give the corresponding oxyblepharismins ( 2 ) on irradiation in vitro and in vivo . The chemical structures of these compounds are elucidated and a mechanism is given for this unusual transformation.

Summary In this report we characterize two macronuclear chromosomes, termed US1 and US2, which are amplified to an extraordinary excess compared with the rest of the macronuclear genome within one Stylonychia lemnae cell clone isolated from the USA.

Summary The macronuclear DNA of the hypotrichous ciliate Stylonychia lemnae contains two highly amplified α- and two highly amplified s-tubulin genes with copy numbers between 30,000 and 150,000 molecules per macronucleus. We show that the transcrip
