Extended Data Fig. 4: LTR-RT diversity in cultivated and wild apples.

a, Comparison of LTR-RT insertions in different assemblies. Genomic sequences harboring LTR-RTs in M. sieversii or M. sylvestris were compared to the syntenic regions of other Malus assemblies to check the presence or absence of LTR-RT insertion in same regions. The percentage of unique LTR-RT insertion was calculated by dividing the number of wild species-specific LTR-RT insertions over the total number of traceable LTR-RTs in the target genome. b, Venn diagram showing percentages of positionally conserved LTR-RT insertions in the three cultivated apple genomes. c, Inheritance of the MYB1 (Mdg_09g022880) locus in the cultivated apples and its contribution to apple fruit skin color. TSD, target site duplication.
