Table 1 Drought survival analyses of ZAT10 transgenic plants using traditional and threshold test methods.

From: A rapid, non-invasive procedure for quantitative assessment of drought survival using chlorophyll fluorescence

  Line Col zat10(i)-1 zat10(i)-3 35S:ZAT10-6 35S:ZAT10-14
(a) # of viable plants post-rehydration 0/7 2/7 1/7 0/7 0/7
(b) Survival time (days) ± s.d. 15.2 ± 1.5 15.3 ± 0.9 15.8 ± 2.5 15.5 ± 1.2 16.2 ± 1.1

  1. (a) Traditional rehydration survival test results. Plants were subjected to drought treatment for 20 days, after which watering was resumed; values indicate the number of plants that recovered within 3 days of rehydration. For each line, n = 7. (b) Threshold survival test results. For control populations, n = 2 for each line; for drought-treated populations, n = 13 for each line. s.d. = standard deviation. Pairwise t-tests were performed against survival times of wild-type Columbia plants, yielding p-values as shown; n.s. = not significant.
