Description
Repetitive DNA makes up about half the olive genome, and its churn may drive the crop's variety. Flavia Mascagni and co-authors compared that repeat landscape in 2026 across twenty olive samples, wild and cultivated. They grouped sequencing reads to profile jumping genes and tandem repeats, then checked full-length copies in two reference genomes.
Wild and farmed trees differed in some jumping gene families, while tandem repeats were richer and more varied in wild forms. Most jumping gene activity dated from before domestication. One reference, a farmed variety, kept more intact jumping genes; the wild one kept more of a second class. The authors say repeat change is a major engine of olive genome diversity.
