Phloem loading in Ricinus cotyledons: sucrose pathways via the mesophyll and the apoplasm

  title={Phloem loading in Ricinus cotyledons: sucrose pathways via the mesophyll and the apoplasm},
  author={Gabriele Orlich and Ewald Komor},
Ricinus communis cv. Carmencita seedlings with their cotyledons incubated in sucrose solution and their hypocotyls cut to induce exudation of phloem sap, constitute a system of sucrose fluxes into and out of the cotyledons. This system was characterized with respect to quasi-steady-state conditions of sucrose uptake and export and then used to investigate the pathways of sucrose during phloem loading. The redistribution of 14C-labelled internal sucrose between the three “compartments… CONTINUE READING
