haplont
English
Etymology
From haploid, ultimately from Ancient Greek ἁπλόος (haplóos, “single, simple”).
Noun
haplont (plural haplonts)
- (biology) Any haplontic organism; any organism whose zygotes undergo zygotic meiosis (meiosis immediately after the fusion of cell nuclei).
- 1933, John Milton Webber, Cytological Features of Nicotiana Glucinosa Haplonts, M. C. Merrill (editorial supervisor), Journal of Agricultural Research, Volume 47, U.S. Department of Agriculture, page 864,
- The behavior of haplont Nicotiana glutinosa is in harmony with the foregoing facts. […] The occurrence of diploid cells in the callus of decapitated haplonts may be attributed to causes similar to those resulting in diploid cells in proximal callus.

- It is thus an amphimictic haplont, but clonal selling gives progeny identical among themselves and with their parents.

- The first transition is a vegetative cell to a gamete, followed by gamete fusion and the production of a zygote. This involves syngamy and in haplont life cycles the 1n gametes fuse to form a 2n motile or non-motile zygote. There can be one stage or two-stage meiosis with resultant haplonts to begin the cycle again.
