aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.
Comparing maize to its wild ancestor teosinte advances our understanding of how it and other cereal crops evolved, and also identifies the genetic variation that can contribute to important agricultural traits.
The machinery that carries out programmed DNA rearrangements is composed of domesticated transposases. One is catalytically active, five play architectural function essential for the accuracy of the process.
Whole genome duplication in Brassica rapa is accompanied by both expansion of the circadian transcriptome and widespread temporal reconfiguration of gene regulatory networks consistent with subfunctionalization among pairs of paralogs.
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.
