a
Rescue for each mutant transgene was scored relative to the rescue obtained with the gETR1 transgene.
b
Results of growth in air and nutations (Fig. 3) were scored as follows: more than 70% rescue, +++; 50% to 70% rescue, ++; 30% to 50% rescue, +; and no rescue, –.
c
Results for growth recovery (Fig. 3) were scored as follows: recovery time was faster, ++++; recovery time was comparable, +++; recovery time was slightly slower, ++; and recovery time was very slow and only slightly faster than the etr1-6;etr2-3;ein4-4 mutants, +.
d
Results for the time for 50% germination on salt (Supplemental Fig. S1) were scored as follows: more than 65% slower, +++++; 20% to 65% slower, ++++; comparable, +++; 15% to 35% faster, ++; and more than 35% faster, +.
