Morphology and molecular phylogeny of two new species of Psammophaga (Rhizaria, Foraminifera) from the west coast of India
In this study, we describe two new species of marine monothalamid genus Psammophaga Arnold, 1982, from the Rajapuri Creek, coastal Maharashtra, India (Arabian Sea). Psammophaga holzmannae sp. nov. is ovoid to spherical shaped, 103-246 µm in length, single aperture, translucent to orange color cytoplasm, outer surface is composed of agglutinated fine clay particles, and ingested mineral grains are concentrated near its aperture. Psammophaga sinhai sp. nov. is oblong, elliptical, or droplet-shaped, 279-448 µm in length, single aperture, yellow olive color cytoplasm, the exterior surface formed of agglutinated fine clay par...

Morphology and molecular phylogeny of two hypotrichous ciliates (Ciliophora, Spirotrichea) from South Korea, including Hemiurosomoida koreana n. sp
Eur J Protistol. 2023 Dec 6;92:126045. doi: 10.1016/j.ejop.2023.126045. Online ahead of print.ABSTRACTThe living morphology, infraciliature, and molecular phylogeny of a new soil ciliate, Hemiurosomoida koreana n. sp., discovered in a sample collected from a mountain in the northeast of South Korea, were investigated. The new species possesses the characteristics of the genus Hemiurosomoida, i.e., a reduced number of frontal-ventral-transverse cirri, three dorsal kineties of which kineties 1 and 2 each bears a caudal cirrus, and a single dorsomarginal kinety. It is distinguishable from congeners and other similar species b...

Morphology, morphogenesis, and molecular phylogeny of Aspidisca koreana n. sp. (Ciliophora, Euplotida) from South Korea
Eur J Protistol. 2023 Dec 1;92:126037. doi: 10.1016/j.ejop.2023.126037. Online ahead of print.ABSTRACTThe morphology, morphogenesis, and molecular phylogeny of a new ciliate, Aspidisca koreana n. sp., discovered in the eastern coast of South Korea, were investigated. The morphological description is based on the observation of living cells, 4'-6-diamidino-2-phenylindole (DAPI) and silver-stained specimens (e.g., protargol, silver nitrate), and scanning electron micrographs. The new species is characterized by having a small body size (17-25 × 15-18 μm in vivo), a distinct peristomial spur on the posterior portion of left...

Genome-wide identification and in-silico analysis of papain-family cysteine protease encoding genes in Tetrahymena thermophila
In conclusion, this study provides the first comprehensive in-silico analysis of TtPFCP genes and encoded proteases. The results would help designing an effective strategy for protease knockout mutant cell lines to discover biological function and to improve the recombinant protein production in T. thermophila.PMID:38088016 | DOI:10.1016/j.ejop.2023.126033 (Source: European Journal of Protistology)

Copterus tyloloricatus (Ciliophora, Suctorea), a new suctorian genus and species
We present the description of the new suctorian genus Copterus gen. n. with type species Copterus tyloloricatus sp. n. from the family Acinetidae, inhabiting the prosomes and urosomes of calanoid copepods from the northern North Pacific Ocean. The new taxon is characterized by (i) an ellipsoidal to triangular, asymmetric, dorsoventrally flattened cell body, which lies horizontally on the lorica surface; (ii) an unflattened lorica; and (iii) the presence of three to five radially arranged bundles of tentacles positioned at the edge of the body or on actinophores.PMID:38016242 | DOI:10.1016/j.ejop.2023.126036 (Source: Europe...
