Success tastes sweet | Sugarcane's complex genetic code has been cracked
08/04/2024
The full sugarcane genome has finally been revealed. The results of work to sequence the plant, which accounts for 80% of the sugar produced worldwide, were published in Nature on 27 March. The five-year operation was the fruit of international collaboration between CIRAD (France), the Joint Genome Institute (JGI) (United States) and CSIRO and QAAFI (Australia).

Cultivated bananas are natural inter-(sub-)specific hybrids selected by man centuries ago. Characterization of the parentage relationships between current cultivars using a "whole genome" approach showed that they were derived from different types of gametes, reduced or not, and recombined or not, mainly generated by diploid or triploid cultivated parents. This work also illustrates the particular involvement of a diploid cultivar, Mchare, which transmitted its complete, non-recombined genome to the main triploid dessert banana plants currently grown.

Analysis of banana genomes has shown that cultivated bananas share common ancestors, originating in New Guinea and resulting from hybridizations between Musa acuminata and Musa schizocarpa species. These early hybrids then spread to Southeast Asia and diversified through hybridization with local subspecies/species of Musa, including a newly identified contributor and an important contributor yet to be discovered.

Three founding ancestral genomes involved in the origin of sugarcane
19/04/2021
Sugarcane is probably the most complex crop genome, combining high polyploidy, interspecificity and aneuploidy. This paper suggests that three, not two, ancestral genomes are involved in modern cultivars adding an additional level of complexity.
