The position of the leaves collected for transcriptome sequencing is circled. b Image of a grafted plant. Healthy young shoots (4–5 cm) with 4–5 leaves were used as scions, healthy young shoots were cut 2–3 cm above the soil level to produce the rootstocks. A 0.7-cm deep vertical incision was made in the middle of the rootstock. The scion was cut into wedges, inserted into the incision. (Both images were drawn and photographed by the author.)
