The FEBS Journal, EarlyView.The C. elegans Shu complex (RFS‐1/RIP‐1/SWS‐1) is a DNA‐dependent ATPase that regulates RAD‐51 filaments during homologous recombination. The trimer preferentially binds 5′‐exposed DNA, remodels RAD‐51 filaments via ATP hydrolysis, and stabilizes filaments through ATP binding.

Meiotic DSBs and the control of mammalian recombination [PDF]
Cell Research, 2012 The laboratories of Galina Petukhova and R Daniel Camerini-Otero have achieved significant technical advances in determining the genome-wide sites of DNA double-strand breaks (DSBs) where the process of genetic exchange between chromatids during meiosis begins. Applying the new approaches to male meiosis in mice, their experimental results considerably

On the origin of crossover interference : a chromosome oscillatory movement (COM) model [PDF]
, 2011 Background: It is now nearly a century since it was first discovered that crossovers between homologous parental chromosomes, originating at the Prophase stage of Meiosis I, are not randomly placed.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis
Journal of Integrative Plant Biology, EarlyView.The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Spatiotemporal regulation of meiotic recombination by Liaisonin [PDF]
BioArchitecture, 2013 Sexual reproduction involves diversification of genetic information in successive generations. Meiotic recombination, which substantially contributes to the increase in genetic diversity, is initiated by programmed DNA double-strand breaks (DSBs) catalyzed by the evolutionarily conserved Spo11 protein. Spo11 requires additional partner proteins for its

Recent advances in the genomics of sugarcane (Saccharum)
Journal of Integrative Plant Biology, EarlyView.This review systematically summarizes advances in sugarcane genomics, evolution, classification, and breeding practices. It identifies key research bottlenecks and proposes an integrated research framework to facilitate predictive sugarcane breeding, which provides valuable references for genetic improvement of other complex polyploid crops.

How to halve ploidy : lessons from budding yeast meiosis [PDF]
, 2012 Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

PLoS Genetics, 2011 Repair of programmed DNA double-strand breaks (DSBs) by meiotic recombination relies on the generation of flanking 3' single-stranded DNA overhangs and their interaction with a homologous double-stranded DNA template.

Journal of Integrative Plant Biology, EarlyView.Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...
