Table 3 Linear regression analysis of cell area, perimeter and single segment changes from 3 DAG to 5 DAG using time-lapse images

From: The development and geometry of shape change in Arabidopsis thalianacotyledon pavement cells

Field R2(area) (1) R2(perimeter) R2(segments) IF (%) (2) Growth rate (%/hour) (3)
1 (N = 6) 0.999 0.999 0.963 ± 0.030 (4) 91 ± 3 (5) 1.89 ± 0.26 (6)
2 (N = 4) 0.998 0.996 0.991 ± 0.007 89 ± 4 1.11 ± 0.18
3 (N = 5) 0.975 0.992 N.D. (7) 88 ± 2 1.42 ± 0.24
  1. (1) R2 represents the R-squared values in linear regression analysis of surface area, cell perimeter, and anticlinal wall segment lengths plotted for populations of cells at 3 and 5 DAG. All p values are smaller than 0.01 during regression analysis.
  2. (2) IF: Isotropy Factor is calculated as the overlap between digitally isotropically amplified 3 DAG cells and the real cell imaged at 5 DAG.
  3. (3) Growth rate was calculated as ((5 DAG area - 3 DAG area)/(3 DAG area * 48))*100%
  4. (4), (5) , (6) Mean ± SD
  5. (7) N.D. Not determined
