Induction of PCD by transient expression of TaLls1.

Experiment	Barrel 1^a	Barrel 2^a	Direct ratio^b	P value^c
A	TaLls1+GUS	EV+GUS	0.42±0.08	<0.01
B	TaLls1_1–178+GUS	EV+GUS	0.35±0.07	<0.01
C	TaLls1_212–397+GUS	EV+GUS	0.98±0.05	>0.05

^a Barrels 1 and 2 were physically identical and the masses of DNA in each barrel were identical. All of the replicates were conducted on the petiole-proximal half of the leaves and then the petiole-distal half. EV, empty vector.

^b Ratios of blue spots that were counted in each barrel. Geometric averages and standard error were calculated from log ratios obtained from 16 pairs of shots.

^c The P value for the direct comparison was calculated from the log ratios using a Wilcoxon signed-ranks test. A significant P value indicates that cell death was induced by TaLls1.
