Localization of fluorescence in EGFP-TFL1 and EGFP-Leavenworthia crassa TFL1 (EGFP-LcrTFL1) lines. TFL1 expression was restricted to the inflorescence meristem (a). By contrast, LcrTFL1 was expressed in the inflorescence apex, floral organs, stem tissue (b) and throughout seedlings (b, inset). im, Inflorescence meristem; f, flower primordium. Bar, 500 μm.
