Summary of early meiotic pairing behavior in well-studied organisms:

	Initial contacts and coupling	Factors involved	Tethering to the NE	Factors involved	Nuclear movements	Factors involved	Sample References
S. cerevisiae	Non-homologous centromeres	Zip1 Rec8 Spo11	Telomeres tether to the NE, near SPB. Loose bouquet	Ndj1 Csm4 Mps3	Telomere led burst movements in 3 axes	Actin	[62] [4] [53]
S. pombe	Co-localization of telomeres and centromeres	Taz1/Rap1 Bqt1/2 Nuf2 Sad1	Telomeres tether to the NE, at SPB. Tight bouquet	sad1 Kms1 Bqt1/2 Taz1/Rap1	Telomere and SPB led continuous movement in mainly 1 axis	Dynein Tubulin Hrs1	[51,72] [27,54]
Z. mays♂	Predominantly homologous centromeres	AFD1 SMC6 Active centromeres	Telomeres gather at nuclear periphery	Pam1	Mostly telomere led movement in 3 axes	Actin tubulin	[73,74] [9]
