Title
Transport and Metabolism of Sucrose versus Hexoses in Relation to Growth in Etiolated Pea Stem

Other claims from this paper (6)
- Observation Hexoses were converted mainly to sucrose in basal epicotyl regions.
- Observation Some hexoses moved through the epicotyl and accumulated at the apex faster than sucrose.
- Association A greater fraction of hexose-derived carbon entered ethanol-insoluble products than sucrose-derived carbon.
- Observation Neither sucrose hexose moiety was preferentially used in metabolite synthesis.
- Observation Supplied sucrose moved intact to the elongation region, then hydrolyzed and equilibrated before moving apically.
- Mechanism The authors infer distinct reactions of transported sucrose and hexoses affect elongation-zone growth.
