Ryegrass leaf fructan synthesis is oxygen dependent and abolished by endomembrane inhibitors.

Valid models are the foundation of systems biology. However, even well-established models may warrant reassessment. A testable feature of the currently accepted vacuolar model for fructan biosynthesis is its independence from metabolic energy at substrate level.

Absence of turnover and futile cycling of sucrose in leaves of Lolium temulentum L.: implications for metabolic compartmentation.

To study the interdependence of sucrose accumulation and its hydrolyzing enzyme, soluble acid invertase (AI; EC 3.2.1.
