“…Furthermore, it has been suggested that Iran, with its close proximity to Central Asia -the center of origin of emblematic fruit trees -and its historic position on the Silk Trade Routes, is a possible secondary center of domestication of apple, grape and apricot (Decroocq et al, 2016;Liang et al, 2019;Liu et al, 2019). However, inferences of the natural and anthropogenic divergence history of wildcrop fruit tree complexes in the Caucasus have been limited by the small number of samples (Decroocq et al, 2016;Liu et al, 2019) and/or genetic markers investigated so far (Amirchakhmaghi et al, 2018;Asanidze, Akhalkatsi, Henk, Richards, & Volk, 2014b;Cornille et al, 2013a;Gharghani et al, 2010;Myles et al, 2011;Volk & Cornille, 2019;Vouillamoz et al, 2006).…”
