VARIATION IN HUMAN MEIOTIC RECOMBINATION
Annual Review of Genomics and Human Genetics, 2004▪ Abstract As recently as 20 years ago, there was relatively little information about the number and distribution of recombinational events in human meiosis, and we knew virtually nothing about factors affecting patterns of recombination. However, the generation of a variety of linkage-based genetic mapping tools and, more recently, cytological ...

Distribution of meiotic recombination sites
Trends in Genetics, 2003Meiotic recombination generates gene conversion and crossover events that are distributed heterogeneously in the genome. Studies in yeast show that initiation of recombination, which occurs by the formation of DNA double-strand breaks, determines the distribution of gene conversion and crossover events that take place in nearby intervals.

Meiotic Recombination and Crossovers in Plants
2008Efforts have been made in recent years to clarify molecular meiotic processes in a large variety of higher eukaryotes. In plants, such studies have enjoyed a boom in the last years with the use of Arabidopsis thaliana together with maize, rice and tomato as model systems.

Mammalian meiotic recombination: a reexamination
Human Genetics, 1994Recombination nodules (RNs) are small electron-dense structures associated with the synaptonemal complex. Two types have been identified: early RNs present during zygonema-early pachynema, which are thought to be involved in gene conversion and synaptic initiation, and late RNs present during mid-to-late pachynema, which are thought to be involved in ...

Meiotic recombination hotspots in plants
Biochemical Society Transactions, 2006Many studies have demonstrated that the distribution of meiotic crossover events along chromosomes is non-random in plants and other species with sexual reproduction. Large differences in recombination frequencies appear at several scales. On a large scale, regions of high and low rates of crossover have been found to alternate along the chromosomes in

Cytological aspects of meiotic recombination
Experientia, 1994This article reviews current views on the mechanisms of meiotic homology searching and recombination. It discusses the relationship between molecular events at meiotic prophase and concomitant cytological processes. The role of the synaptonemal complex and other meiosis-specific structures is discussed.

Modulation of Meiotic Recombination
2014Meiotic recombination is one of the principal forces creating the genetic diversity that drives evolution and is the fundamental instrument underlying most crop breeding programmes. A greater understanding of the control of recombination in crop plants would enable manipulation of this process to improve the speed and accuracy of plant breeding.
