Meiotic recombination is essential for faithful segregation of homologous chromosomes during gametogenesis. The progression of recombination is associated with dynamic changes in meiotic chromatin structures.

A BIRD´S-EYE VIEW OF CHROMOSOMES DURING MEIOTIC PROPHASE I [PDF]
The present review aims to summarize the research carried out in relation to meiosis in birds, especially by observing the protein axes of the chromosomes in prophase I of meiosis. This line of research, initially developed in Argentina, has provided key

Principles of meiotic chromosome assembly revealed in S. cerevisiae [PDF]
During meiotic prophase, chromosomes organise into a series of chromatin loops emanating from a proteinaceous axis, but the mechanisms of assembly remain unclear.

Essential and checkpoint functions of budding yeast ATM and ATR during meiotic prophase are facilitated by differential phosphorylation of a meiotic adaptor protein, Hop1 [PDF]
A hallmark of the conserved ATM/ATR signalling is its ability to mediate a wide range of functions utilizing only a limited number of adaptors and effector kinases.

Evidence that MEK1 positively promotes interhomologue double-strand break repair [PDF]
During meiosis there is an imperative to create sufficient crossovers for homologue segregation. This can be achieved during repair of programmed DNA double-strand breaks (DSBs), which are biased towards using a homologue rather than sister chromatid as ...

Meiotic sex chromosome cohesion and autosomal synapsis are supported by Esco2.
In mitotic cells, establishment of sister chromatid cohesion requires acetylation of the cohesin subunit SMC3 (acSMC3) by ESCO1 and/or ESCO2. Meiotic cohesin plays additional but poorly understood roles in the formation of chromosome axial elements (AEs)

Synaptonemal Complexities and Commonalities [PDF]
Formation of synaptonemal complex and high levels of homologous recombination are the hallmarks of meiotic prophase. The relationship between these two processes has been the subject of intense study for nearly 50 years. Recent findings highlight the differences and commonalities of this relationship in different species.

Crystal structure of Hop2-Mnd1 and mechanistic insights into its role in meiotic recombination [PDF]
In meiotic DNA recombination, the Hop2-Mnd1 complex promotes Dmc1-mediated single-stranded DNA (ssDNA) invasion into homologous chromosomes to form a synaptic complex by a yet-unclear mechanism.

Human disease locus discovery and mapping to molecular pathways through phylogenetic profiling
Genes with common profiles of the presence and absence in disparate genomes tend to function in the same pathway. By mapping all human genes into about 1000 clusters of genes with similar patterns of conservation across eukaryotic phylogeny, we ...

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.
