Plasmodesmata Frequency per Pitfield Area at Cell Interfaces in Leaves of C₃ and C₄ Species.

(A) Rice, C₃.

(B) Wheat, C₃.

(C) S. viridis, C₄.

(D) Maize, C₄.

Closed circles correspond to the values obtained from the M-BS cell interface. Open circles correspond to the values obtained from the M-M cell interface. Solid line and dashed line correspond to the regression lines generated using the plotted values from M-BS cell interface and M-M cell interface, respectively. Analysis using SPSS Statistics software with P value < 0.05 revealed M-BS cell interface and M-M cell interface regression lines to be statistically different in (A), (B), and (D) but not in (C). The plasmodesmata frequency per pitfield area was calculated using the linear equation, y = mx + b, where y is the plasmodesmata frequency, m is the slope, x is the pitfield area, and b is the intercept. R² is coefficient of determination, where a value of 1 indicates that the regression line perfectly fits the data while a value of 0 indicates that the line does not fit the data at all.
