What's the difference between acropetal and basipetal?
Acropetal
Definition:
(a.) Developing from below towards the apex, or from the circumference towards the center; centripetal; -- said of certain inflorescence.
Example Sentences:
(1) The amounts of radioactive indole-3-acetic acid that moved, both basipetally and acropetally, through short sections of bean epicotyl were measured at 15 degrees and 25 degrees C in the presence and absence of 2,3,5-triiodobenzoic acid.
(2) Continued development of new conidia resulted in an acropetal chain which became disarticulated after cytolysis within the conidiogenous cell.
(3) Germination of the phragmobasidia occurred by acropetal chains of yeast cells, ballistospores or hyphae.
(4) Results are interpreted as supporting a metabolically dependent component of the acropetal movement of auxin in bean epicotyls.
(5) In culture, X. emmonsii grew moderately fast at 25 degrees C, showed minimal growth at 37 degrees C, and failed to grow at 40 degrees C. It produced acropetal chains of one-celled (rarely two-celled) conidia laterally and terminally directly from vegetative hyphal cells.
(6) The basipetal transport may intensify the polarity by recycling auxin that is moving acropetally.
(7) After radioautographic experiments, culmcutting-experiments and experiments with intact rye in the 5--6 leaf-stage we have found that the agens is transported acropetal in the xylem of the plants after uptaking by the roots up to 3 days.
(8) Anaerobic conditions inhibit metabolically dependent movement (transport) thus reducing basipetal but not acropetal movement.
(9) The specific processes of formation may lead to acropetal, basipetal, or random formation of endoarthroconidia or exoarthroconidia.
(10) Anaerobic conditions totally prevent this immobilization and reduce acropetal uptake but not the amount of indoleacetic acid moving into the upper parts of the section; there is, therefore, no evidence for acropetal transport.
(11) Acropetal transport remained below 5% of basipetal transport of tracer during these intervals.
(12) Pine was radically different in that it showed no difference between acropetal and basipetal transport rates and had very low rates.
(13) Acropetal and basipetal movement of indole-3-acetic acid through coleoptiles of Avena sativa L. was studied.
(14) Low temperature and this second compound each inhibited acropetal efflux of indole 3-acetic acid more than they did the influx.
