akaryoteadj.n.

Brit.

/eɪˈkarɪət/,

/eɪˈkarɪəʊt/, U.S.

/ˌeɪˈkɛriˌoʊt/

Origin: A borrowing from Greek, combined with an English element. Etymons: a- prefix⁶, Greek καρυωτός.

Etymology: < a- prefix⁶ + Hellenistic Greek καρυωτός nut-shaped < ancient Greek κάρυον nut (see karyo- comb. form) + -ωτός (see -otic suffix).

Biology. rare.

A. adj.

Of a cell or a stage in cell division: characterized by the lack of a distinct nucleus.

1909 E. R. Lankester Treat. Zool. I. 2 This conception may be expressed by saying that the stage is akaryote but is not moneran.

1928 Ann. Bot. 42 354 The stage of protomitotic nuclear division in the vegetative soma is separated from the reproductive part of the life-cycle by a condition of the nuclei usually referred to as the ‘akaryote stage’.

1979 Canad. Jrnl. Bot. 57 2510/2 The akaryote stage is thus confirmed to be prophase I of meiosis by the presence of synaptonemal complexes.

1920 I. F. Henderson & W. D. Henderson Dict. Sci. Terms 8/2 Akaryote, a cell in which the nucleoplasm has not collected together to form a nucleus; a non-nucleated cell.

1992 P. Forterre in Nature 23 Jan. 305/3 I therefore propose the neutral terms akaryotes (without nucleus) and synkaryotes (with nucleus) for a natural classification without prejudice.

2011 P. Forterre in Res. Microbiol. 162 77/2 I suggested in 1992 to replace the terms prokaryote and eukaryote by neutral ones..such as akaryote and synkaryotes (without and with nucleus) to designate the two types of known cellular organization..but this proposal was completely ignored.
