Fig. 1. Chromosomal localization and distribution of FveMLO.

A and FaMLO B genes in F. vesca and F. ×ananassa genomes, respectively. The seven chromosomes of F. vesca were named as Fvb1–Fvb7 while F. ×ananassa was named as Fvb1–1 to Fvb1–4, Fvb2–1 to Fvb2–4, Fvb3–1 to Fvb3–4, Fvb4–1 to Fvb4–4, Fvb5–1 to Fvb5–4, Fvb6–1 to Fvb6–4 and Fvb7–1 to Fvb7–4, respectively, to indicate four subgenomes within each chromosome. Different color of F. ×ananassa subgenomes indicates their respective diploid progenitors, namely F. viridis (yellow), F. iinumae (green), F. nipponica (gray), and F. vesca (orange)³⁹ Putative strawberry MLO gene chromosome locations were visualized using MapChart 2.3 software26. The relative chromosome size was indicated by the unit Mbp.
