Phenotypes of Leavenworthia crassa TFL1/L. crassa LFY ortholog (LcrTFL1/LcrLFY) double transgenic lines in a lfy (a–d) or tfl1 (e–h) mutant background. Phenotypes of LcrTFL1/LcrLFY/lfy transgenic lines are variable. Approximately half of the lines failed to form fertile flowers, instead forming compressed leafy axes (a) or broccoli-like inflorescences with apetalous flowers (c). In some cases, inflorescence stems lacked any paraclades (d). When flowers were formed, the earliest flowers tended to make extra petals (b). Phenotypes of LcrTFL1/LcrLFY/tfl1 transgenic lines exhibited primarily LcrTFL1-like phenotypes, including extra petals (e), conversion of flowers into shoots (f), and long pedicels (e– f). Some lines, however, produced terminal flowers (g).
