Tracking down the jumping genes of maize

The "jumping genes" of maize have finally been mapped by an international team led by researchers at the University of California, Davis, and the Cold Spring Harbor Laboratory. The discovery could ultimately benefit the breeding ...

Team defines meaningful part of maize genome

Using a genetic mapping technique developed at Florida State University, FSU and Cornell University researchers have shown that a small percentage of the entire maize genome is responsible for almost half of a plant's trait ...

Method to find bad mutations may improve maize crops

Cornell researchers have developed a way to predict bad mutations in the maize genome, addressing a major challenge for breeders trying to grow better crops and feed rising populations. The researchers found regions of the ...

Mapping the maize genome

Positional cloning is a genetic mapping technique used to pinpoint the location of specific traits of interest, such as disease-causing genes or mutations, within the genome. Very simply, this map-based technique involves ...

A-maize-ing double life of a genome

Early maize farmers selected for genes that improved the harvesting of sunlight, a new detailed study of how plants use 'doubles' of their genomes reveals. The findings could help current efforts to improve existing crop ...

Aging cells lose their grip on DNA rogues

(Phys.org)—Transposable elements are mobile strands of DNA that insert themselves into chromosomes with mostly harmful consequences. Cells try to keep them locked down, but in a new study, Brown University researchers ...
