NaCl tolerance of plants expressing CaN is based on root function

Scion/root stock	Plants
	Initial, n	Survival, %
PKY/PKY	35	8.8 (0–17.6)*
A9/PKY	24	33.3 (14.5–52.1)
PKY/A9	24	66.7 (47.9–85.5)
A9/A9	33	69.7 (54–85.4)

T₂ progeny of lines homozygous for Kn^r (vector control, PKY) and CaN expression (A9) were the resource for scions and root stocks for wedge-grafted plants evaluated for NaCl tolerance. PKY scion onto PKY root stock (PKY/PKY). PKY scion onto A9 root stock (PKY/A9), A9 scion onto PKY root stock (A9/PKY), and A9 scion onto A9 root stock (A9/A9).
