In zebrafish, the distance between the posterior two stripes is one of the earliest markers of segment length [presumptive somite -I, where somite I is the most recently formed somite (Pourquié and Tam, 2001)] (Fig. 1E,F; supplementary material Fig. S1H,I).
Minor: I do not understand how the two stripes are representing "West".
The distribution of holes, crossings and splits over all eight stripes was found to be different from random (χ test, p < 0.009 for each feature): holes were more common in the sixth and seventh stripes (26% and 30%, respectively), splits were most common in the fourth stripe (19%), and crossings were most common in stripes six, seven, and eight (52%, 62 % and 19, respectively).
The system can be regarded as a 3D superlattice with one thin film (thickness a) and one stripe-shaped layer (thickness c along the z direction and width b along the x direction) stacked alternatively; the spacing between two adjacent stripes is d.
In this paper, we propose a 3D superlattice nanostructure based on thin films of Bi2Te3 topological insulator, with one thin film (thickness a) and one stripe-shaped layer (thickness c along the z direction and width b along the x direction) stacked alternatively; the spacing between two nearby stripes is d, as shown in Figure 1.
Between four and six Eve stripes were present, with only one out of four embryos showing all seven Eve stripes.
In dcr-2R416x embetweenbethree and fived fivEveve stripes were expressed.
In dcr-2L811fs Xembryos, between four and six Eve stripes were expressed.
The boxed segments were cropped out and the distance between stripes was measured in the image.
We show that despite being created by the largely independent activity of five discrete enhancers, the seven eve stripes are sculpted by the same basic kinetic phenomena - a low burst frequency outside of stripes, and a high burst frequency inside the stripe that increases over time to sharpen the contrast between stripe and interstripe regions.
