Complex migration history is revealed by genetic diversity of tomato samples collected in Italy during the eighteenth and nineteenth centuries.

ABSTRACT: Native to South America, the tomato is now grown almost worldwide. During its domestication and improvement, important selection signatures were fixed in certain agronomic and adaption traits. Such traits include fruit morphology, which became a major target for selection over the centuries. However, little is known about precisely when some mutations arose and how they spread through the germplasm. For instance, elongated fruit variants, originating both via mutations in SUN and OVATE genes, may have arisen prior to domestication or during tomato cultivation in Europe. To gain insights into the tomato admixture and selection pattern, the genome of two tomato herbarium specimens conserved in the Herbarium Porticense (PORUN) was sequenced. Comparison of the DNA of herbarium samples collecte
