Distinct domestication signals in Asian and European pears. a Distribution of FST values across the whole genome of Asian pears. b Distribution of FST values across the whole genome of European pears. c Distribution of ROD values across the whole genome of Asian pears. d Distribution of ROD values across the whole genome of European pears. Yellow arrows indicate genes in selective sweeps of only Asian pears. Purple arrows indicate genes in selective sweeps of only European pears. Red arrows indicate genes in selective sweeps common to both the Asian and European pears. The horizontal dotted line indicates the threshold of FST 5% and ROD > 0.5, respectively. e Overlap of selective sweeps and QTLs related to fruit traits in pear. The inside lines of each linkage group indicate selective sweeps, while the outside lines of each linkage group indicate QTLs. A total of 208 selective sweeps in Asian pears showed coincidence with QTLs related to fruit traits, including sugar, acidity, stone cell, firmness, fruit size, fruit shape, as well as traits for preharvest fruit drop and fruit harvest time. A total of 14 selective sweeps in European pears showed coincidence with QTLs related to fruit traits, including sugar, acidity, firmness, fruit size, fruit shape, and skin color
