Arrangement of the AtFLSs in A. thaliana genome as well as their corresponding syntenic homologs in B. rapa chromosomes and subgenomes showed duplication, retention and distribution of BrFLSs. All six AtFLSs are located on chromosome 5. AtFLS2 to −5 are clustered in a 7.5-kb region. AtFLS1 only has one syntenic ortholog BrFLS1 on chromosome A10 and subgenome LF. There are no orthologs of AtFLS6. AtFLS2 to −5 have five synteny orthologs distributed in different chromosomes and subgenomes. The black and green bars represent the chromosomes of A. thaliana and B. rapa. The LF, MF1, and MF2 in brackets below gene names indicate the different subgenomes of B. rapa.
