It is worth noting that the two sucrose metabolizing enzymes, sucrose synthase and sucrose-phosphate synthase, were both discovered by Leloir and Cardini (1955) (see Preface ).

Phloem loading of sucrose is decisive for the speed of mass flow, because sucrose is the dominant solute in the sieve tube sap of nearly all plant species. The interaction of sucrose metabolism, starch storage and phloem export in source leaves and the effects on sugar status in phloem was presented. The sucrose concentrations was revealed by a NMR imaging method. 

Rates of metabolism can be determined for each sugar from the experimental time period in which incorporation into insolubles is linear. Rates of metabolism determined in this way change with leaf development. The metabolism rate for both sugars increases during early development and then declines, however the rate of sucrose metabolism increases more than the rate of I -FS metabolism over the same developmental period. This indicates a changing relative contribution by the two sucrose metabolizing enzymes. 

Table I. The relative contribution of invertase and sucrose synthase to sucrose metabolism in developing soybean leaves...

The rate of carbon import and sucrose metabolism increased very rapidly during early development. Most of the increased rate of sucrose metabolism could be accounted for by a sharp rise in the flux through invertase. As the leaf became photosynthetically competent, the rate of utilization of carbon imported from mature leaves declined, however about one-half of sucrose metabolism remained through invertase. 

The use of fluorinated sucroses as tracers of sucrose metabolism in order to differentiate between glycolysis started by invertase and glycolysis started by sucrose synthase should be quite useful in determining the in vivo flux of these paths and the large differences in phosphate metabolism which accompany the two routes of carbon metabolism.

First examples for plant ceU cultures were reported for following the sucrose metabolism with a 400 MHz instrument/ However, sugar concentrations needed to be very high ( 200 mM) to detect all carbon atoms. Also glucosylation of phenolic compounds (arbutin, ursubin) could be observed when precursor concentrations were around 8 A breakthrough...
