The long-awaited sequencing of the banana genome might help save the yellow fruit from imminent collapse.

Bananas are a staple food around the world. But the humble yellow fruit faces pests and diseases that threaten to wipe it out across the globe, from convenience stores in Iowa to rural markets in Uganda.

In an effort to save bananas from imminent demise, scientists have now sequenced the banana genome for the first time, a challenging feat and a major advance in the field.

The accomplishment opens the way for developing better banana crops that are naturally resilient against parasites and other stresses.

“The banana is very important, especially for tropical and subtropical countries,” said Angélique D’Hont, a geneticist at CIRAD, an agricultural research center in Montpelier, France. “Because the future of the banana is in danger, the sequence will help to produce resistant bananas and avoid the utilization of pesticides. It will be much easier now to identify genes which are important.”
