Yes dear submission system, I'm sure that me typing the department and the zip code of all my co-authors is really important and useful for you.

Highlights:
• Around 2 Mb with no recombination with the M gene, and different from the ZW locus
• The M gene region contains 34 genes, among them the one coding for the androgenic gland hormone, involved in male sexual differentiation
• Likely recent emergence of the masculinizing M allele
• Around 2 Mb with no recombination with the M gene, and different from the ZW locus
• The M gene region contains 34 genes, among them the one coding for the androgenic gland hormone, involved in male sexual differentiation
• Likely recent emergence of the masculinizing M allele

The M gene is one of several sex determinants (ZW system, f-element, Wolbachia) in A. vulgare. It is thought that the masculinizing M allele has been selected to re-establish balanced sex ratios in some pops in which the feminizing f-element, another sex determinant, is present.

The discovery of triploid enset with advantageous traits opens new avenues for future breeding programs, with the potential of obtaining novel triploid varieties with higher yields. This would help enhance food security.

- analysis using a Bayesian linear mixed-effects model shows that the pseudostem is generally bigger for triploid ensets compared to cultivated diploids, e.g. 42 to 75% larger for a 6-year old individual. 6/8

- triploid ensets were likely derived from sexual crosses between cultivated individuals (involving unreduced gametes). This happened independently multiple times. 5/8

- discovery of triploid cultivated enset individuals, representing almost a third of our sample. Triploids were dominant in the south while almost absent in the most northern transects. They were grouped into 33 clonal lineages vs 121 lineages for diploids.

Enset (Ensete ventricosum) belongs to the Musaceae family, like bananas and plantains, but it is not grown for its fruits, but for its starch-rich pseudostem and corm. It is a crucial crop for food security in Ethiopia. It is clonally-propagated and until now was considered exclusively diploid.
