Cavalier-Smith T
Protoplasma . 2021 Dec; 259(3):487-593. PMID: 34940909
I thoroughly discuss ciliary transition zone (TZ) evolution, highlighting many overlooked evolutionarily significant ultrastructural details. I establish fundamental principles of TZ ultrastructure and evolution throughout eukaryotes, inferring unrecognised ancestral TZ...

Protoplasma . 2020 Jan; 257(3):621-753. PMID: 31900730
Palaeontologically, eubacteria are > 3× older than neomura (eukaryotes, archaebacteria). Cell biology contrasts ancestral eubacterial murein peptidoglycan walls and derived neomuran N-linked glycoprotein coats/walls. Misinterpreting long stems connecting clade neomura...

Protoplasma . 2018 Apr; 255(5):1517-1574. PMID: 29666938
Infrakingdom Rhizaria is one of four major subgroups with distinct cell body plans that comprise eukaryotic kingdom Chromista. Unlike other chromists, Rhizaria are mostly heterotrophic flagellates, amoebae or amoeboflagellates, commonly...

Eur J Protistol . 2017 Oct; 61(Pt A):137-179. PMID: 29073503
Uniquely in eukaryotes, euglenoid pellicles comprise longitudinal proteinaceous, epiplasmic strips underlain by microtubules. Contradictory interpretations of pellicle microtubule duplication and segregation assumed opposite microtubule polarity from kinetoplastid Euglenozoa and conservative...

Cavalier-Smith T
Protoplasma . 2017 Sep; 255(1):297-357. PMID: 28875267
In 1981 I established kingdom Chromista, distinguished from Plantae because of its more complex chloroplast-associated membrane topology and rigid tubular multipartite ciliary hairs. Plantae originated by converting a cyanobacterium to...

Yi Z, Berney C, Hartikainen H, Mahamdallie S, Gardner M, Boenigk J, et al.
FEMS Microbiol Ecol . 2017 Jun; 93(8). PMID: 28575320
We performed high-throughput 18S rDNA V9 region sequencing analyses of microeukaryote (protist) communities at seven sites with depths ranging from 0 to 1450 m in the southern part of Lake...

Philos Trans R Soc Lond B Biol Sci . 2016 Dec; 372(1713). PMID: 27994119
Evolving multicellularity is easy, especially in phototrophs and osmotrophs whose multicells feed like unicells. Evolving animals was much harder and unique; probably only one pathway via benthic 'zoophytes' with pelagic...

Eur J Protistol . 2016 Nov; 56:250-276. PMID: 27889663
Discoveries of numerous new taxa and advances in ultrastructure and sequence phylogeny (including here the first site-heterogeneous 18S rDNA trees) require major improvements to euglenozoan higher-level taxonomy. I therefore divide...
