Journal ArticleDOI
Sucrose Accumulation in the Sugarcane Stem Is Regulated by the Difference between the Activities of Soluble Acid Invertase and Sucrose Phosphate Synthase
TL;DR: Major differences in Suc accumulation among the population were attributed to the difference between activities of SAI and Suc phosphate synthase, provided SAI is below the critical threshold concentration.
Journal ArticleDOI
A non-invasive measurement of phloem and xylem water flow in castor bean seedlings by nuclear magnetic resonance microimaging
TL;DR: In this article, a flow sensitive NMR microimaging technique was applied to measure directly the in-vivo water flow in 6-d-old castor bean seedlings, and the achieved in-plane resolution of the technique allowed discrimination between xylem and phloem water flow.
Journal ArticleDOI
Sucrose uptake by cotyledons of Ricinus communis L.: Characteristics, mechanism, and regulation.
TL;DR: Cotyledons of Ricinus communis take up externally supplied sucrose at a rate of up to 150 μmol/h/g fresh weight, which is very high when compared with other sugar transport systems of higher plants, but the rate of uptake is subject to feedback inhibition by internal sucrose, and is regulated during growth of the seedlings.
Journal ArticleDOI
The hexose-proton cotransport system of chlorella. pH-dependent change in Km values and translocation constants of the uptake system.
Ewald Komor,Widmar Tanner +1 more
TL;DR: The proton concentration in the medium affects the maximal velocity of sugar uptake with a Km of 0.3 mM (high affinity uptake) and a decrease in high affinity sugar uptake is observed, in parallel the activity of a low affinity uptake system (Km of 50 mM) rises.
Journal ArticleDOI
Identification of immunologically related proteins in sieve-tube exudate collected from monocotyledonous and dicotyledonous plants
Christian Schobert,Lucian Baker,Judit Szederkényi,Pia Großmann,Ewald Komor,Hiroaki Hayashi,Mitsuo Chino,William J. Lucas +7 more
TL;DR: Analysis of sieve-tube exudates revealed the presence of distinct sets of polypeptides in seven monocotyledonous and dicotylingonous plant species and specific antibodies were employed to identify major polypePTides.
