A. Jamai ; M. Laloi ; A. Bourbouloux ; M. Valantin ; S. Delrot | 1996Uptake of the dipeptide [H-3]Leu-Leu into leaf discs from mature broad bean (Vicia faba L.) was characterized. Uptake was maximal at p H 6.0 and appeared to be mediated by three systems with apparent K-m values of 20 mu M, 350 mu M and 43 m M, r[...]article/chapitre/communication
The solute relations of the upper epidermis of the third leaf of barley (Hordeum vulgare L. cv. Klaxon) were studied by analysing vacuolar saps extracted from individual cells. Their osmolality (nanolitre osmometry) and the concentrations of K, [...]article/chapitre/communication
N. Bernstein ; W. Silk ; A. Lauchli | 1995Elongating leaf tissue, which in monocotyledonous species is a small region located near the leaf base, requires a continuous supply of nutrients to maintain cell expansion and is, therefore, highly susceptible to nutrient disturbances. The obje[...]article/chapitre/communication
R. Schaufele ; H. Schnyder | 2001The effect of defoliation on the deposition of carbon (C) and nitrogen (N) and the contribution of reserves and current assimilates to the use of C and N in expanding leaf tissue of severely defoliated perennial ryegrass (Lolium perenne L.) was [...]article/chapitre/communication
The distribution of solutes between epidermal, mesophyll and bundle-sheath cells in barley (Hordeum vulgare L. cv. Klaxon) leaves was studied by analysing extracts obtained from single cells with a modified pressure probe. Activity of the cytopl[...]article/chapitre/communication
The concentrations of vacuolar solutes in different cells of the upper epidermis of the third leaf of barley (Hordeum vulgare L.) were studied in leaves of different ages grown under different irradiances (120 or 400 mu mol photons . m(-2). s(-1[...]article/chapitre/communication
