RFL genes in a region of the A. lyrata genome orthologous to the region of the A. thaliana genome depicted in Figs. 1 and 3. a A dot matrix representation illustrating the duplication of a region containing 3 RFL genes at positions indicated by the double headed in the A. lyrata genome; all three genes and the surrounding sequences correspond to the AtRFL3 (At1g12620) region of A. thaliana. The bracket indicates the region of the Arabidopsis genome that is duplicated in A. lyrata (dotted lines along the y axis). A second duplication occurs at the position of AtRFL4 (At1g12700); in this case the duplication involves the AtRFL2 gene (At1g12300). b Depiction of the analyzed segment of the A. lyrata genome. Arrows indicate the direction and orientation of the RFL genes. The dotted lines indicate duplicated segments: one containing three genes at the location corresponding to AtRFL3 and the other containing two genes apparently derived from AtRFL2, with one copy at the location of AtRFL2 and the other at the location of AtRFL4
