Figure 6: Similar length constant of the Bcd gradient profiles in wt and dmpd embryos.

(a) Shown are the mean Bcd gradient profiles from wt and dmpd embryos plotted as ln(B/Bmax) against AP position x/L. Here both B and Bmax are background-adjusted intensities without any further adjustments. The solid lines represent linear fits (y=−6.78x+0.46, R squared for linear regression; R2=0.999 for wt embryos; y=−6.77x+0.58; R squared for linear regression, R2=0.998 for dmpd embryos). (b) Shown are calculated λ values of Bcd gradient profiles from individual wt and dmpd embryos (n=15 and 13, respectively). These values were obtained from fitting the individual Bcd intensity profiles to an exponential function. Shown are the mean and s.d. for these two groups, along with the P-value obtained from Student’s t-test.
