  • Transgenic lines overproducing the yeast-derived invertase in either the vacuole (Vac-Inv) or apoplast (Apo-Inv) were utilised to analyse the effect of the altered sugar levels in sink and source organs on the expression of sugar transporters, as well as the endogenous cell wall invertase and inhibitors in these plants. (sun.ac.za)
  • In this study, a similar strategy of transgenic plant analysis was employed to expand our insight into the regulation of sugar partitioning. (sun.ac.za)
  • Crabtree-positive yeasts also have increased glycolytic flow, or increased uptake of glucose and conversion to pyruvate, which compensates for using a portion of the glucose to produce ethanol rather than biomass. (wikipedia.org)
  • Over 200 structurally distinct HMOs have been identified 7 with chain lengths from 3 to 15 carbohydrate units, composed of five monosaccharides: glucose, galactose, N -acetylglucosamine, fucose, and N -acetylneuraminic acid (also known as sialic acid). (nature.com)
