Meiotic homologous chromosomes synapse and undergo crossing over (CO). In many eukaryotes, both synapsis and crossing over require the induction of double stranded breaks (DSBs) and subsequent repair via homologous recombination. In these organisms,

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

We developed an improved cytological protocol for producing high quality, light microscope images of plant meiotic chromosomes. Because the technique works on species with small genomes and thick microsporocyte cell walls, it should be useful for stu

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

We have found novel phenotypes for the previously studied Arabidopsis thaliana (L.) Heynh. meiotic mutant ahp2. These phenotypes were revealed by analysis of reconstructions of normal and ahp2 nuclei that were imaged using transmission electron micro

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

Meiotin-1 is a chromatin associated, conserved protein found in meiocytes immediately preceding and during meiosis and is thought to have a role in determining the higher order structure of meiotic chromosomes [Riggs and Hasenkampf: Chromosoma 101:92

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
