fructan/hypoxia

Anaerobic conditions developing under an ice cover affect winter survival and spring regrowth of economically important perennial crops. The objective was to compare, during a prolonged period of low (<2%) O2 at low temperature, the concentration of carbohydrates of four plant species contrasting in

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. The effects of limiting energy

In terms of gene expression and carbohydrate metabolism, the response of wheat seedlings to hypoxia is dramatically different from the anoxic response. Total carbohydrate content of roots increased 4-fold during 6 days of hypoxia, with a 17-fold increase in fructans. In contrast, anoxically treated

To study the interdependence of sucrose accumulation and its hydrolyzing enzyme, soluble acid invertase (AI; EC 3.2.1.26), in fructan-accumulating temperate grasses and cereals, experiments were performed in which sucrose synthesis was abolished in leaves of Lolium temulentum by four independent

Ophiopogon japonicus is a traditional Chinese medicine used to treat cardiovascular disease. Recent studies have confirmed the anti-ischemic properties of a water-soluble β-D-fructan (MDG-1) from O. japonicus. The sphingosine 1-phosphate (S1P) signaling pathway is involved in its cytoprotective
