 | | A note of caution: Katz and Riley (2001) argue that the process of generation of "gene-sized" MAC chromosomes has evolved independently in a variety of ciliate lineages; hence, this character is not a valid basis for phylogenetic inference. |
| | While this web-page focuses on Stichotrichs, to the exclusion of Hypopotrichs and, notably, Euplotes, it should be noted that much of what is understood about Spirotrich MACs and MAC development is the result of the efforts of a talented set of Euplotes workers, nearly all of whom recently have, regrettably, abandoned Euplotes for other endeavors. |
| | Stichotrichs, like all ciliates, are eukaryotic microbes that employ two different nuclei in each cell, the germline nucleus or micronucleus (MIC), and the somatic macronucleus (MAC), a specialized gene expression organelle. |
