Portable genome sequencing and CEBA meeting in French Guiana

Updated: Oct 25, 2023

Frédéric and Marie-Ka, together with Bérénice Lafon, spent 15 days in French Guiana at the Pasteur Institute in Cayenne with long-term collaborator Benoit de Thoisy. The main objective of the mission was to obtain a reference genome for the newly described armadillo species (Dasypus guianensis) using the paratype specimen preserved in the local JAGUARS collection ( To this aim, we performed DNA extractions and Nanopore long read sequencing on site using two MinION-Mk1C portable sequencers. The ConvergeAnt team also attended the annual meeting of the Center for the Study of Biodiversity in Amazonia (CEBA) during which Frédéric presented Mathilde's PhD results on species delimitation in the long-nosed armadillo complex that led to the discovery of Dasypus guianensis. Finally, we had the opportunity to dissect another giant anteater specimen that was sampled for genome and transcriptome sequencing. As always, a very fruitful stay!
