Arachis advances, breaking new ground: groundnut genome successfully sequenced

g-nut-flower ARS-USDA wEarly this month, an international team made a giant breakthrough in groundnut research, successfully sequencing the groundnut (Arachis hypogaea) genome. This fruitful outcome was the sum of several years of effort, multiplied by teamwork bringing together scientists from Asia, Latin America and USA.

Some of the players in this illustrious team are old friends, well known within GCP circles, and include:

Groundnuts are also known as peanuts. According to Rajeev Varshney, improving groundnut varieties to be more drought-, insect- and disease-resistant can help farmers in developed nations produce more groundnuts with fewer pesticides and other chemicals, thus improving food security and  livelihoods.

Whereas groundnuts were successfully bred for intensive cultivation for millennia, compared to other crops, relatively little was known about their genetic structure because of its complexity, according to Peggy Ozias-Akins.

David Bertioli adds: "Until now, we've bred peanuts relatively blindly, as compared to other crops. We've had less information to work with than we do with many crops, which have been more thoroughly researched and understood."

Dave Hoisington concludes: "With the release of the peanut genome sequence, researchers will now have much better tools available to accelerate the development of new peanut varieties with improved yields and better nutrition."
