Growth habits of grafted inflorescence stems from A . thaliana . Floral stem grafts wilt immediately after sealing the graft (A) and if successful recover within 24 hours by standing upright (B). Successful floral stem grafts will maintain shoot apical dominance (C; 7 DAGr) and develop extended cauline shoot branches (D; 14 DAGr) with healthy reproductive siliques (E; 22 DAGr). A grafted plant was pruned to remove all reproductive siliques and at the cauline nodes, new cauline leaves and shoots were produced leading to the formation of new reproductive siliques (F; 60 DAGr).
