Bananas, thought to have been domesticated 7,000 years ago in New Guinea, may have a more complicated history than initially assumed, according a new study from the peer-reviewed Frontiers in Plant Science.<\/em><\/span><\/p>\n

\u201cIdentifying the ancestors of cultivated bananas is important, as it will help us understand the processes and the paths that shaped the banana diversity observed today, a crucial step to breed bananas of the future.\u201d<\/b><\/p>\n

Author Dr. Mathieu Rouard, Bioversity International<\/p><\/blockquote>\n

<\/div>\n

Cultivated bananas<\/a> are sterile and produce seedless fruits. They are descended from wild ancestors which produced seeds, but the connection between the original seed-filled fruits and today’s bananas found in grocery stores<\/a> is not well understood. <\/span><\/p>\n

<\/div>\n

\u201cHere we show that most of today\u2019s diploid cultivated bananas that descend from the wild banana M. acuminata<\/em> are hybrids between different subspecies. At least three extra wild \u2018mystery ancestors\u2019 must have contributed to this mixed genome thousands of years ago, but haven\u2019t been identified yet,\u201d explained Dr. Julie Sardos, a scientist at The Alliance of Bioversity International and CIAT in Montpellier, France, and the study\u2019s first author. <\/span><\/p>\n

Second corresponding author Dr. Mathieu Rouard, likewise at Bioversity International, said: \u201cIdentifying the ancestors of cultivated bananas is important, as it will help us understand the processes and the paths that shaped the banana diversity observed today, a crucial step to breed bananas of the future.\u201d<\/span><\/p>\n

<\/div>\n

The results of the study bring new light to the geographic spread of wild bananas and its impact on bananas today. <\/span><\/p>\n

<\/div>\n

\u201cBreeders need to understand the genetic make-up of today\u2019s domesticated diploid bananas for their crosses between cultivars, and this study is a major first step toward the characterization in great detail of many of these cultivars.\u201d<\/span><\/p>\n

The future of bananas<\/strong><\/h5>\n

The study authors concluded by explaining that their work has direct implications on the evolution<\/a> of banana crops going forward, as well as conservation, collection and breeding of this modern staple food. <\/span><\/p>\n

Sardos said: \u201cBased on these results, we will work with partners to explore and genotype wild banana diversity in the three geographic regions that our study pinpointed, with the hope to identify these unidentified contributors to cultivated bananas. It will also be important to investigate the different advantages and traits that each of these contributors provided to cultivated bananas.\u201d<\/span><\/p>\n
