Genomic Flexibility Through Extrachromosomal Amplifications: A Leishmania Survival Strategy

Atia Amin, Ana Victoria Ibarra‐Meneses, Mathieu Blanchette, Christopher Fernandez‐Prada, David Langlais

This study shows Leishmania parasites use extrachromosomal DNA amplification to adapt to drug pressure, with linear and circular amplicons forming through recombination events.
