In plants, male reproductive development is extremely sensitive to adverse climatic
environments and (a) biotic stress. Upon exposure to stress, male gametophytic organs …

The nematode Caenorhabditis elegans is now a major model organism in biology. The
choice of Sydney Brenner to adopt this species in the mid-1960s and the success of his …

Recombination rate and linkage disequilibrium, the latter a function of population genomic
processes, are the critical parameters for mapping by linkage and association, and their …

Sex differences in overall recombination rates are well known, but little theoretical or
empirical attention has been given to how and why sexes differ in their recombination …

Aging animals display a broad range of progressive degenerative changes, and one of the
most fascinating is the decline of female reproductive function. In the model organism …

Meiotic crossovers are essential for ensuring correct chromosome segregation as well as for
creating new combinations of alleles for natural selection to take place. During meiosis …

Sexual reproduction requires the production of haploid gametes (sperm and egg) with only
one copy of each chromosome; fertilization then restores the diploid chromosome content in …

Diatoms, an evolutionarily successful group of microalgae, display high levels of
intraspecific genetic variability in natural populations. However, the contribution of various …

For most organisms, chromosome segregation during meiosis relies on deliberate induction
of DNA double-strand breaks (DSBs) and repair of a subset of these DSBs as inter-homolog …

Caenorhabditis nematodes form an excellent model for studying how the mode of
reproduction affects genetic diversity, as some species reproduce via outcrossing whereas …
