Haploid meiosis in Arabidopsis: double-strand breaks are formed and repaired but without synapsis and crossovers.

PloS one - 1 Jan 2013

Cifuentes Marta, Rivard Maud, Pereira Lucie, Chelysheva Liudmila, Mercier Raphael

Abstract excerpt

Two hallmark features of meiosis are i) the formation of crossovers (COs) between homologs and ii) the production of genetically-unique haploid spores that will fuse to restore the somatic ploidy level upon fertilization. In this study we analysed meiosis in haploid Arabidopsis thaliana plants and a range of haploid mutants to understand how meiosis progresses without a homolog. Extremely low chiasma frequency...
