Mutations in the BREVIPEDICELLUS (BP) gene of Arabidopsis thaliana condition a pleiotropic phenotype featuring defects in internode elongation, the homeotic conversion of internode to node tissue, and downward pointing flowers and pedicels. We have c

During mitotic prophase, chromosomes progressively compact to their metaphase length. In contrast, meiotic chromosomes condense moderately until late in prophase I, then they condense more dramatically (coil) to their fully condensed state. Meiotin-1

The synaptonemal complex — the chaperone of crossing over

Autor: Clare A. Hasenkampf

During meiosis homologous chromosomes pair and exchange homologous chromosome segments. The synaptonemal complex (SC) forms between paired chromosomes. The role of the SC in the process of reciprocal exchange of flanking markers is a matter of debate

Ahp2 (Hop2) function in Arabidopsis thaliana (Ler) is required for stabilization of close alignment and synaptonemal complex formation except for the two short arms that contain nucleolus organizer regions

A cytological comparative analysis of male meiocytes was performed for Arabidopsis wild type and the ahp2 (hop2) mutant with emphasis on ahp2’s largely uncharacterized prophase I. Leptotene progression appeared normal in ahp2 meiocytes; chromosomes
