Structural analysis of motif (Additional file 4) suggests that they mainly form two kinds of structure in sRNAs; firstly, the whole motif forms a stem loop structure (like motif M5) and secondly, the motif is present as two stem loop structures including the unpaired region between them (like motif M6).
As well, two stems were collected and processed at 10, 40, 60, 100 and 150 days after girdling.
One obvious constraint is that the extracted graphs cannot be general graph patterns, but must be cliques as any two stems in our pattern must be related.

This is particularly surprising as the two stem cell populations are by necessity linked, in that they need to produce offspring in the correct ratio, as well as the fact that CySCs support GSC self-renewal through BMP production (Leatherman & Dinardo, 2010).
An RNA secondary structure is said to contain a pseudoknot if there exist two stems related as shown in Fig. 3.
If L3 = 0, the two stems are taken as a continuous helical stem for the calculation but only half of the value is given to the S1-S2 stock to account for the quasi-continuous nature of the stacked stems.
