autogamyn.

Brit.

/ɔːˈtɒɡəmi/, U.S.

/ɔˈtɑɡəmi/,

/əˈtɑɡəmi/,

/ɑˈtɑɡəmi/

Origin: Formed within English, by compounding. Etymons: auto- comb. form¹, -gamy comb. form.

Etymology: < auto- comb. form¹ + -gamy comb. form. In sense 1 after German Autogamie ( A. Kerner von Marilaun Die Schutzmittel der Blüthen (1876) 6); compare allogamy n., xenogamy n. at xeno- comb. form .

1. Botany. Self-fertilization; esp. the self-pollination of a flower. Frequently contrasted with allogamy.

1877 C. Darwin Let. 4 Oct. (1903) II. 413 I wish that I had used some such terms as autogamy, xenogamy, etc.

1878 W. Ogle tr. A. Kerner von Marilaun Flowers & their Unbidden Guests 9 (note) I understand by autogamy [Ger. Autogamie] the fecundation of a flower by the pollen from the andrœcium of the same flower.

1907 F. E. Clements Plant Physiol. & Ecol. v. 127 Self-pollination is also called autogamy, and cross-pollination allogamy. The latter is the rule among plants, though autogamy is a frequent occurrence.

1939 Amer. Midland Naturalist 22 330 Owing to the small size of the flowers and the comparatively large stigma, autogamy in closing of flowers, even if insect pollination fails, is hardly prevented.

2001 Ann. Bot. 88 995/1 Among the Brazilian Goodyerinae orchids studied here, there is at least one case suggestive of autogamy (automatic self-pollination).

2. Biology. In a single-celled organism: the fusion of a pair of haploid nuclei from the same individual within a single cell. Also: the fusion of sister cells.

1898 Jrnl. Royal Microsc. Soc. 548 It seems an extreme case of autogamy, and can only be of use in bringing about a reconstruction of the nuclear material.

1934 Science 19 Jan. 57/2 Two of the gamete nuclei of the single animal undergoing autogamy fuse to form a synkaryon.

1977 T. I. Storer et al. Elements Zool. (ed. 4) xv. 267/2 The process of autogamy is a nuclear reorganization resembling conjugation but occurs within one individual.

1998 L. Margulis & K. V. Schwartz Five Kingdoms (ed. 3) ii. 186/2 In Actinophrys, two cells (but not their nuclei) may fuse just before they undergo autogamy.
