The adaptive roles of aneuploidy and polyclonality in Leishmania in response to environmental stress KU Leuven Institute of Tropical Medicine University of Antwerp
Aneuploidy is generally considered harmful, but in some microorganisms, it can act as an adaptive mechanism against environmental stress. Here, we use Leishmania-a protozoan parasite with remarkable genome plasticity-to study the early steps of aneuploidy evolution under high drug pressure (using antimony or miltefosine as stressors). By combining single-cell genomics, lineage tracing with cellular barcodes, and longitudinal genome ...
