Table I. Positional parameters for nuclear position in Arabidopsis epidermal cells in darkness

MinR, MaxR, and D in dark-adapted epidermal cells of the wild-type, gl1, phot1, phot2, and phot1phot2 leaves were measured. D was normalized against MaxR in each cell, respectively. Each value shows the mean ± se. On average, 13 epidermal cells were observed in each of five leaves from different plants. The asterisk shows that the values are significantly different from those of gl1 (P < 0.05, Student's t test).
