Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia [PDF]

open access: hybridThe FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Multivariate signals of population collapse in a high-throughput ecological experiment. [PDF]

open access: yesEcology
Abstract Anticipating population declines is a crucial goal of conservation ecology. Recent conceptual work suggests that populations facing growing stressors should exhibit sequential shifts in behavior, morphology, and abundance before declining to extinction.

Crosstalk between G-protein and Ca2+ pathways switches intracellular cAMP levels [PDF]

open access: yes, 2001
Cyclic adenosine monophosphate and cyclic guanosine monophosphate are universal intracellular messengers whose concentrations are regulated by molecular networks comprised of different isoforms of the synthases adenylate cyclase or guanylate cyclase and ...

An electrophysiological and kinematic model of Paramecium, the "swimming neuron".

open access: yesPLoS Computational Biology, 2023
Paramecium is a large unicellular organism that swims in fresh water using cilia. When stimulated by various means (mechanically, chemically, optically, thermally), it often swims backward then turns and swims forward again in a new direction: this is ...

Survival Rate and Growth of Fighting Fish Larvae (Betta splendens Regan) Fed on Various Live Foods

open access: yesJurnal Akuakultur Indonesia, 2007
Larval of fighting fish (Betta splendens Regan) requires precise live foods for its growth and survival. In this experiment, fish larvae were fed on either Paramecium + Artemia, Paramecium + Artemia + Tubifex, Paramecium + Moina, or Paramecium + Moina +

Photosynthesis dependent acidification of perialgal vacuoles in theParamedum bursaria/Chlorella symbiosis. Visualization by monensin [PDF]

open access: yes, 1992
After treatment with the carboxylic ionophore monensin theChlorella containing perialgal vacuoles of the greenParamecium bursaria swell. TheParamecium cells remain motile at this concentration for at least one day.

RNA interference reveals the escape response mechanism of Paramecium to mechanical stimulation

open access: yesBiophysics and Physicobiology, 2023
In Paramecium, a mechanical stimulus applied to the posterior portion of the cell causes a transient increase in membrane permeability to potassium ions, transiently rendering the membrane in a hyperpolarized state.
