Figure 1

A) Cross-section of Arabidopsis hypocotyl showing the two phases of secondary development. B) In Arabidopsis grafting, young seedlings are cut into two through hypocotyl, and the hypocotyl of shoot (scion) part and the root (stock) part are then re-attached in the desired combination. C) Schematic picture of the ga1-3 vs wild-type (WT) grafting experiment. GA from the WT scion was able to rescue xylem expansion in the hypocotyl of the GA deficient ga1-3 stock.
