In the stems the vessels are usually arranged in a continuous ring near the stem surface.
In dicots (e.g., most trees) cambium a layer of actively dividing cells between xylem (wood) and phloem (bast) tissues is usually arranged in a continuous ring; in woody members, new layers of tissue are produced annually.
Using immunofluorescence microscopy and Western blotting of parasite-infected RBCs, we observed that the intraerythrocytic parasite was enclosed in a continuous ring of PVM at early stages of parasite development while at the segmented schizont stage, the PVM appeared to be integrated in the cluster of newly formed merozoites.
The works in this wonderful exhibition look as if they came out of a forest haunted by witches: a log tied into a knot, a perfect sphere covered in pine bark, a tree stump with a rusty doorknob and lock embedded in it, a heavy branch made into a continuous ring.
The works in the wonderful exhibition at Lelong look as if they came out of a forest haunted by witches: a log tied into a knot, a perfect sphere covered in pine bark, a tree stump with a rusty doorknob and lock embedded in it, a heavy branch made into a continuous ring.
There is a log tied into a knot, a log embedded with baseballs, a perfect sphere covered in pine bark, a heavy branch made into a continuous ring and a tree stump that has grown around a rusty doorknob and lock.
In Equisetum, we immunodetected the MLG epitope in the thickened cell walls of the strengthening tissue and the epidermis, as well as in cell walls of a continuous ring of parenchymatous tissue located between the central cavity and the vascular bundles.
Under control conditions Plin A-YFP in fibroblasts and adipocytes uniformly localised to the LD surface and formed a continuous ring in a single x y slice (Fig. 4b).
Given a continuous ring, at least in the in vitro situation, with no GTP turnover (or no added nucleotide) there is no filament shortening, meaning constriction requires the filaments to slide along each other as the ring decreases in diameter and the membrane deforms.
Careful analysis of cellular tomograms (Video 1 and Figure 1A, bottom) revealed that the dots were in fact 2D projections of filamentous structures encircling the cell and likely forming a continuous ring, disrupted in the images at the top and bottom by the missing wedge of the tomography method.
Transmission electron microscope micrographs showed the featureless microstructure of amorphous molybdenum, which was further ascertained by the appearance of a continuous ring pattern in the selected area electron diffraction pattern (SAED).
