Continuous SFT-stimulated systemic signals rescue flowering and morphogenetic defects of sft. (A) A demonstration graft. A donor 35S:SFT is grafted (boxed) onto a receptor sft rootstock with dormant axillary buds (AXL). Flowering response is followed in the released lateral shoots of the rootstock. (B) Complementation of sft by graft-transmissible 35S:SFT-stimulated systemic signals. A receptor sft shoot (right) with three successive normal SUs, each terminated by a regular inflorescence (arrows), is shown. Leaves of the rescued SUs are numbered. (C) Reversion of a rescued sft shoot after removal of the 35S:SFT donor. The last normal inflorescence (Inf) and the subsequent sft VI (Inset) are shown. (Scale bars: 3 cm.)
