membranous sacs associated with cilia of paramecium.	a membranous system associated with the cortical cilia of paramecium putrinum is described. a sac lies below the cortical kinetosomes and extensions from it pass along the kinetodesmal fibre to lie near, or make contact with, the parsomal sac and also pass deep into the cytoplasm to pass close to a mitochondrion. because of its widespread occurrence in this and other species it is suggested that the system plays a physiologically active role.	1978	689246
[effect of local uv irradiation of the generative nucleus on the vegetative functions of the infusorian, paramecium putrinum].	the influence of the generative nucleus on the vitality in three clones of paramecium putrinum was studied. the selective functional inactivation of the micronucleus (mi) was achieved with a local ultraviolet microbeam. after irradiation of micronuclei these soon disappeared and the irradiated cells perished shortly afterwards. in the part of uv treated-subclones the macronucleus (ma) fragmentation was discovered. it is possible that the fragments of ma are some kind of functional replacement of ...	1978	734780

accumulation of selenium in a model freshwater microbial food web.	the transfer of selenium between bacteria and the ciliated protozoan, paramecium putrinum, was examined in laboratory cultures. the population growth of the ciliate was not inhibited in the presence of the highest concentrations of dissolved selenite or selenate tested (10(3) micrograms liter-1). experiments with radioactive 75selenite or 75selenate indicated that accumulation of selenium by ciliates through time was low when feeding and metabolism were reduced by incubating at 0 degrees c. howe ...	1994	8085812
phylogenetic relationships of the subclass peniculia (oligohymenophorea, ciliophora) inferred from small subunit rrna gene sequences.	peniculine ciliates have been recognized as a distinct higher taxon of ciliates for almost 50 years. however, phylogenetic relationships within the subclass peniculia are still unsettled. to contribute to our understanding of their phylogeny and provide evidence for the position of urocentrum turbo, we sequenced its small subunit (ss) rrna gene and the ssrrna genes from lembadion bullinum, frontonia sp., paramecium caudatum, paramecium multimicronucleatum, paramecium putrinum, and paramecium woo ...	2000	11140457

paramecium putrinum (ciliophora, protozoa): the first insight into the variation of two dna fragments - molecular support for the existence of cryptic species.	paramecium putrinum (claparede & lachmann 1858) is one of the smallest (80-140 μm long) species of the genus paramecium. although it commonly occurs in freshwater reservoirs, no molecular studies of p. putrinum have been conducted to date. herein we present an assessment of molecular variation in 27 strains collected from widely separated populations by using two selected dna fragments (its1-5.8s-its2-5'lsu rdna and coi mtdna). both the trees and haplotype networks reconstructed for both genome ...	2014	24486879
