LFS is the single tomato ortholog of DRN and DRNL. (A) Recombination-based mapping placed LFS between the PCR markers YCm34 and YCm68 (Dataset S1, Table S5). Two identified lesions in Solyc05g013540 are indicated by arrowheads. The AP2 box and a LFS-specific box are color-coded (SI Appendix). (B) Phylogenetic relationship of closest LFS homologs in select mono- and dicotyledonous plants. Nodes show bootstrap values. (C) Arabidopsis drn-1 drnl-2 whole seedling. (Inset) The SAM. (D) Top view of a tomato lfs plant. (Scale bars in C and D: 250 µM.)
