Mapping-by-sequencing (or SHOREmapping) has revitalized the powerful concept of forward genetic screens in plants. However, as in conventional genetic mapping approaches, mapping-by-sequencing requires phenotyping of mapping populations established from crosses between two diverged accessions. In addition to the segregation of...

DNA methylation is important for the silencing of transposons and other repetitive elements in many higher eukaryotes. However, plant and mammalian genomes have evolved to contain repetitive elements near or inside their genes. How these genes are kept from being...

The complexity of DNA repair mechanisms infers that xenobiotics, derived from food and medicinal plants, may interfere in the process, activating or inhibiting repair. Different flavonoids were investigated, at the highest non-toxic concentration, for their capacity to modulate DNA repair...

Ethyl methanesulfonate (EMS) is a monofunctional ethylating agent that has been found to be mutagenic in a wide variety of genetic test systems from viruses to mammals. It has also been shown to be carcinogenic in mammals. Alkylation of cellular...

Genes underlying mutant phenotypes can be isolated by combining marker discovery, genetic mapping and resequencing, but a more straightforward strategy for mapping mutations would be the direct comparison of mutant and wild-type genomes. Applying such an approach, however, is hampered...
