1846 T. Keightley Notes Bucolics & Georgics of Virgil 99 If this be the true reading, sua is an ablative case contracted by the figure synizesis.
1861 F. A. Paley Æschylus' Persians (ed. 2) 81 (note) Κυάνεον... Compare inf...πορϕυρέᾳ. In both places Hermann retains the uncontracted form, in which there is synizesis, against κυανοῦν and πορϕυρᾳ̑ of later editors.

1905 C. E. McClung in Biol. Bull. IX. 329 I would suggest that..a new descriptive word be applied to the condition of the nucleus in which the chromatin is found massed at one side of the vesicle, without regard to whether it is a normal phenomenon or not. To carry out this idea I shall call this stage the ‘synizesis’ of the chromatin.
1921 Ann. Bot. 35 367 In this paper the term synizesis is adopted for the tightly contracted phase of the nucleus, following the usage which has become customary in the literature of animal cytology.
1931 Jrnl. Exper. Zool. 58 299 Synezesis stages were present, but mixed with secondary spermatocytes.
1933 Cytologia IV. 270 By the use of the methods employed in the studies reported here, the chromatin is drawn into a tight knot (synizesis) at the stages at which synapsis takes place.
1979 Hereditas XCI. 87/1 In the zygotene of the arctic brambles there is a polarised stage called a synizesis. The synizesis is a zygotene bouquet in which mass contraction has occurred.

1931 Amer. Jrnl. Bot. 18 370 The next stage involves a very rapid shortening of the spireme, the opening out of the spirals, and the transition to an interwoven thread system, which..persists until toward the climax of synizetic sensitiveness.
1933 Cytologia IV. 271 Synizetic stages were studied in asynaptic plants which showed little associations of homologous chromosomes at metaphase.
