Eve protein expression dynamics and variability in Clogmia albipunctata compared to Drosophila melanogaster . (A) A time-space plot indicating the shifting positions of Eve stripes 1 to 7 (S1-S7) from the appearance of each stripe until T8. Lines represent linear interpolation between measured time points. C. albipunctata data are shown in black, D. melanogaster data in grey. Vertical axis indicates time (flowing downward); horizontal axis indicates percent antero-posterior (A-P) position (where 0% is the anterior pole). The graph only shows the region between 25 and 95% A-P position. (B) The total extent of shifts in peak positions (in % egg length, EL) for each stripe (S1-S7) in C. albipunctata (black) and D. melanogaster (grey) measured from the appearance of each stripe until the end of T8. (C) Shows the width of the entire region expressing Eve protein (in % EL) measured from the peak of stripe 1 to the peak of stripe 6 (C. albipunctata, black; D. melanogaster, light grey) or 7 (D. melanogaster only, dark grey) across time classes in C14A (T5-T8). Error bars represent one standard deviation from the mean. The difference in width between the C. albipunctata Eve domain (peak of stripe 1 to stripe 6), and that of D. melanogaster (stripe 1 to stripe 7) is statistically significant (P < 0.0005).
