Scientists sequenced nut genome

Scientists at the University of California-Davis have sequenced the genome of a variety of walnuts. The work is pioneering because the plant is the first in his family to have his DNA fully mapped. The information obtained from this discovery can contribute to the genetic improvement process of walnut and collaborate in the selection of desired characteristics, such as insect resistance, diseases and even drought.


The sequenced variety is known as Chandler and was chosen for its economic importance. Currently, this type of walnut occupies half of the entire area devoted to culture in the American state of California, responsible for 99% of all walnuts produced in the United States.

From the mapping of this variety, geneticists David Neale and Charles Langley intend to unravel the genome of other nuts. "Chandler-type trees bear fruit late; To advance the harvest we can use molecular markers and develop plants that can be harvested earlier, "explains Neale.


Nuts are rich in omega-3s (healthy type of fat) and their moderate consumption may reduce the risk of heart disease. Information on genetic sequencing is public and available on this site.
