gametophoren.

Brit.

/ɡəˈmiːtə(ʊ)fɔː/,

/ˈɡamᵻtəfɔː/, U.S.

/ɡəˈmidəˌfɔr/

Origin: Formed within English, by compounding. Etymons: gameto- comb. form, -phore comb. form.

Etymology: < gameto- comb. form + -phore comb. form, after sporophore n.

Botany.

Originally: the sexual form or generation of a plant (= gametophyte n.) (now rare). In later use: any structure, esp. a modified branch or filament, bearing a gametangium or gametes in a bryophyte or other non-flowering plant.

1885 W. R. M'Nab in Sci. Proc. Royal Dublin Soc. 4 452 If we now take the plant that bears the gametangia, it is easy to denominate it the gametophore (a term I have now used for some time).

1894 Bot. Gaz. 19 21 The metanema is..very probably a highly specialized gametophore.

1895 D. H. Campbell Struct. & Devel. Mosses & Ferns i. 2 The gametophyte itself may show two well-marked phases, the protonema and the gametophore.

1919 J. N. Martin Bot. for Agric. Students xvi. 421 Although the leafy plants or gametophores of Moss are not all of the gametophyte, they are the conspicuous part of it, the protonemas being microscopic in size.

1953 Bryologist 56 237 Simultaneously with this, the number of lobes in the female gametophore and the number of archegonia is also diminished.

2005 Evolution 59 2354/2 At sexual maturity, gametophores produce gametes in either male or female gametangia (antheridia and archegonia respectively).

Derivatives

gametoˈphoric adj. of, relating to, or of the nature of a gametophore.

1895 D. H. Campbell Struct. & Devel. Mosses & Ferns vi. 155 The sexual organs are borne either separately or together at the summit of the gametophoric branches.

1950 Amer. Biol. Teacher 12 107/2 Cultures with this medium were producing gametophoric buds.

2004 H. Holtorf et al. in A. J. Wood et al. New Frontiers Bryol. 55 An essential part of the functional genomics project was the generation of novel EST sequence information from three cDNA libraries specific for protonemal, gametophoric, and sporophytic material.
