AHP2 is required for bivalent formation and for segregation of homologous chromosomes in Arabidopsis meiosis.

The Plant journal : for cell and molecular biology - 1 Oct 2003

Abstract excerpt

A new Arabidopsis meiotic mutant has been isolated. Homozygous ahp2-1 (Arabidopsis homologue pairing 2) plants were sterile because of failure of both male and female gametophyte development. Fluorescent in situ hybridisation showed that in ahp2-1 male meiocytes, chromosomes did not form bivalents during prophase I and instead seemed to associate indiscriminately. Chromosome fragmentation, chromatin bridges and...
