Effect of plant hormones on sucrose uptake by sugar beet root tissue discs.
Abscisic acid (ABA), auxins, cytokinins, gibberellic acid, alone or in combination were tested for their effects on short-term sucrose uptake in sugar beet (Beta vulgaris cv USH-20) roots. The effect of ABA on active sucrose uptake varied from no effect to the more generally observed 1.4-to 3.0-fold stimulation. A racemic mixture of ABA and its trans isomer were more stimulatory than ABA alone....
متن کاملSucrose uptake and compartmentation in sugar beet taproot tissue.
Active sucrose uptake by discs of mature sugar beet (Beta vulgaris L. cv GW-D2 and USH-20) root tissue shows a biphasic dependence on external sucrose. At concentrations up to 20 millimolar sucrose, the active uptake mechanism appears to approach saturation, with an apparent K(m) of 3.6 millimolar. At higher external sucrose concentrations, a linear dependence becomes obvious indicating the pro...
متن کاملTurgor regulation of sucrose transport in sugar beet taproot tissue.
Sink tissues that store osmotically active compounds must osmoregulate to prevent excessively high turgor. The ability to regulate turgor may be related to membrane transport of solutes and thus sink strength. To study this possibility, the kinetics of sugar uptake were determined in sugar beet (Beta vulgaris L.) taproot tissue discs over a range of cell turgors. Sucrose uptake followed biphasi...

متن کاملThe synthesis of sucrose by extracts of the root of the sugar beet.
There is no doubt that synthesis of sucrose does occur in the leaf of the sugar beet but the root has not previously been shown to possess a sucrosesynthesizing system. Buchanan et al. (1952) and Buchanan (1953), in photosynthetic experiments with 14CO2, demonstrated the formation of sucrose phosphate in the leaves of the sugar beet as well as of other plants. They postulated that the sucrose p...
