Our project is a collaboration between scientists in Canada, Argentina, and the USA and aims to understand the genomic mechanisms of genome expansion in vizcacha rats of Argentina. Using genetic approaches we tested whether this expansion occurred through complete genome duplication, as has been proposed recently, or alternatively through expansion of small repetitive elements. We found support for the second mechanism.
Impact
This work furthers understanding of genome evolution of a critically endangered species that is specifically adapted to a harsh environment in Argentina. It provides clarity to a controversy concerning the mechanisms of genome expansion in this rodent.
Student Experience
One graduate student participated in fieldwork in Argentina. One postdoc participated in fieldwork and is a co-author on one peer reviewed paper.
