Culture-independent molecular methods based on the amplification, cloning and sequencing of small-subunit ribosomal RNA genes (SSU rDNAs) are powerful tools to study the diversity of microorganisms. Despite so, the eukaryotic microbial dive...
Dependence between volumes of protoplast and lorica in lugol-fixed tintinnid ciliates [0.03%]

Tripartite tubular hairs (mastigonemes) on the anterior flagellum of protists in the stramenopile taxon are responsible for reversing the thrust of flagellar beat and for cell motility. Immunoprecipitation experiments using antibodies direc...
Conservation of POPs, the plant organellar DNA polymerases, in eukaryotes [0.03%]

POPs, plant organellar DNA polymerases, have been isolated from various photosynthetic eukaryotes. Previously, we purified the native POP of Cyanidioschyzon merolae(CmPOP) from whole cellular extracts and showed that CmPOP has DNA polymeras...
Possible roles of phospholipase A(2) in the biological activities of Acanthamoeba castellanii (T4 Genotype) [0.03%]
溶血磷脂酶A(2)在卡氏棘阿米巴(T4基因型) 生物活性中的可能作用

Parisa Nakhostin Mortazavi et al.
Using phospholipases A(2)-specific spectrophotometric assays, it was shown thatA. castellaniilysates and their conditioned medium exhibit phospholipase activities. The extracellular levels of PLA(2)detected were significantly reduced compar...
Stress-induced pseudocyst formation--a newly identified mechanism of protection against organic solvents in acanthamoebae of the T4 genotype [0.03%]

Differentiation into highly resistant double-walled cysts is a major mechanism allowing amphizoic acanthamoebae to survive under long-lasting, unfavourable environmental conditions. We found that relatively low concentrations of methanol, a...
Introns, alternative splicing, spliced leader trans-splicing and differential expression of pcna and cyclin in Perkinsus marinus [0.03%]
