(1) A unique stone stele was found in one of the mounds, similar in form and decoration to the picture-stones of Gotland.(2) The decree ordering the assessment is a forceful document, and it and the assessments were inscribed on an imposing stele , set up on the Acropolis.(3) All roots possessed a central stele of vascular tissues, surrounded by a few layers of cortical cells, and an outer layer of epidermis.(4) The catalogue describes an obelisk and a stele brought back as symbols of imperial conquest.(5) What is uncertain, and is a critical caveat to the entire reconstruction, is that the top edge of the fragment is a portion of the top edge of the stele to which it belonged, as is maintained.(6) Once inside the symplast, radial transport across the root to the central stele and, subsequently, unloading into the xylem are necessary for translocation to the shoot.(7) In shoots, epidermal tissue is said to be rate-limiting for organ elongation, whereas in roots the stele or other inner cell layers may be the growth-limiting tissue.(8) Cross-sections of the asparagus stem revealed a primary rind and the stele , the vascular tissue had a scattered bundle system, with closed collateral bundles.(9) They suggested that ions would move directly from the pericycle to the xylem vessels, rather than through the internal stele tissues.(10) A few years ago one of the Taewongun's steles could still be seen on the grounds of the recently restored Kyongbok Palace in Seoul.(11) Outwardly-rectifying K + dependent currents displaying sigmoidal activation kinetics have been identified in stelar cells from Arabidopsis, maize and barley roots.(12) However, this phenomenon can be attributed simply to the stelar apoplast having an electrical potential more negative than the bathing medium and, thereby, concentrating cations in the xylem.(13) One useful character of stelar development is the maturation of the primary xylem.(14) If cytosolic Na + in stelar cells is higher than quoted above and if xylem Na + is at the lower end of the above range, then the energy difference could favour the passive leakage of Na + into the xylem.(15) After 2-3 weeks post-treatment, hypodermal, exodermal and stelar lignifications were far more extreme in the more basal regions of sulfide-treated roots than in the controls.
