Cut the stem close to the heart.
The gills are subdecurrent (running only a small way down the length of the stem), close to crowded together, narrow, and sometimes forked near the stem.
The gills have an adnate to decurrent attachment to the stem, close to subdistant, white at first then cream to pale ochre.
The tight hairpin formed by the element is similar to the structures processed by Drosha and Dicer, and the location of the mature miRNA sequence, in the stem close to the 3' end of the structure, is consistent with the mode of cleavage thought to be employed by the Dicer (Figure 4B).
There, the region of the lower hairpin stem towards the basal segments and the upper stem close to the Drosha cleavage site were identified as thermodynamic most stable [ 31].
Because of the position of the new roots is close to water surface and they are connected to the stem, close to the formatted aerenchyma, they have more access to oxygen than the old root system.
At the tissue level PDR1 was expressed in root tips, in the hypodermal passage cells (HPCs), as well in proximity of the root vasculature and in nodes of the stem, close to the axillary buds.
The miR-96(+57T>C) substitution introduces a base-pairing mismatch, decreasing the free energy value and creating an enlarged RNA bulge in the pre-miR-96 stem, close to the Dicer cleavage site (Fig. 2A).
The Mg(H2O 62+ complex at site 5 is found at the extremity of the 5′ 3′ stem, close enough to G1 O5′/N7/O6, A2 N7/5′- pro-Rp OP, and G3 O6/N7 for outer-sphere coordination and to the 5′-PO4– of A2 and G3 for electrostatic stabilization.
