The model organism Tetrahymena thermopile carries two nuclei with distinct genomes: an unrearranged germline genome with five chromosomes, and a somatic genome reduced in size by a third and with 181 chromosomes.

The centromeres in Malassezia species, by breakage or inactivation, facilitate genome rearrangements that can result in varying karyotypes and contribute to the evolution of these species.

Sequence analyses show a pfhrp3 deletion mechanism involves duplication of chromosome 11 segment, which is normally removed via negative selection, and specific conditions are needed for spread including low transmission.

Novel segmental chromosome amplifications in Candida albicans provide rapid adaptation to the most widely used antifungal drugs.

Precise control of microtubule architecture greatly increases the force that the spindle can exert on chromosomes.

Fluorescent derivatives of a bacteriophage protein that binds double-stranded ends can trap and label genome-destabilizing double-strand DNA breaks in bacterial and human cells, and illuminate the origins of spontaneous DNA breakage in both.

Genomic data for the parasites that cause visceral leishmaniasis provides the first global picture of the diversity and evolution of the pathogen and the epidemiology of this fatal tropical disease.

Genome-wide chromatin mapping during bacterial-fungal cocultivation identifies the Myb-like transcription factor BasR as the major regulatory node of bacteria-triggered production of fungal secondary metabolites.

Bilallelic mutations of FANCM, a DNA-damage response gene whose heterozygous mutations predispose to breast cancer, are involved in a familial case of Primary Ovarian Insufficiency establishing a link between infertility and cancer.
