Molecular perspectives of chromosome pairing at meiosis

BioEssays, 1994
AbstractIdeas about the mechanisms that regulate chromosome pairing, recombination, and segregation during meiosis have gained in molecular detail over the last few years. The purpose of this article is to survey briefly the shifts in paradigms and experiments that have generated new perspectives.

THE EFFECT OF COLCHICINE ON CHROMOSOME PAIRING

Canadian Journal of Genetics and Cytology, 1977
Beginning at 120 hours prior to first metaphase of meiosis (MI) a 0.03% aqueous solution of colchicine was injected into the boot of pentaploid (hexaploid triticale × tetraploid wheat) hybrids developing at 20 °C ± 1° under continuous illumination. Colchicine applied 40 h or less prior to MI had no effect on chromosome pairing, while its application 40

The Analysis of Chromosome Pairing

1975
In respect to chromosome pairing, two situations may be distinguished: non-competitive pairing, in which only two possible partners are available, and competitive pairing, where more than two potential partners are available, but where nevertheless only two at a time can finally pair sufficiently effectively to form a chiasma.

Chromosomal Control of Preferential Pairing in Nicotiana

Science, 1961
A stock of tobacco with 23 pairs of tobacco chromosomes and one substituted pair from Nicotiana glutinosa was available. An amphiploid of this tobacco with N. tomentosiformis was synthesized in order to test whether preferential pairing is determined by the homologies of the chromosomes or ...
