Sugar uptake by cotton tissues

Sugar uptake by cotton tissues. Leaf disk versus cultured roots. Hendrix, Donald L. (West. Cotton Res. Lab., Phoenix, AZ 85040, USA). Plant Physiol., 74(1), 16-20 (English) 1984. CODEN: PLPHAY. ISSN: 0032-0889. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) The tissue accumulation of sucrose, glucose, and fructose was studied in cultured cotton (Gossypium hirsutum) roots and leaf disks. Sucrose uptake by both tissues from high apoplastic concns. was independent of pH but had a slightly acidic pH optimum from low concns. Like other higher plant tissues, cotton root cells accumulate sucrose via a "saturable", inhibitor-sensitive mechanism and a linear, inhibitor-resistant mechanism. The linear mechanism of sucrose uptake is not as pronounced in leaf disk data as it is in root data. Further, sucrose uptake by cotton leaf disks is more resistant than uptake by root cells to pH alterations, inhibitors, and monosaccharides in the uptake medium. The saturable phase of sucrose influx into cotton root is eliminated by glucose, fructose, and high pH. Sucrose influx into both tissues is not altered by osmotica up to 200 millosmolar. Sucrose accumulated by both tissues is rapidly converted to other chem. forms, esp. in root tissue where only ~50% remains as neutral sugars 1 h following the start of radiolabel exposure. Although the entry of radiolabeled sucrose is faster in abraded leaf disks, they give the same response patterns to pH, inhibitors, and monosaccharide as do unabraded disks. The sucrose accumulation kinetics of cotton roots and leaf disks differ. These differences may be related to the physiol. 57-50-1 and 50-99-7 are just another two chemicals used in this study. roles (source vs. sink) of the 2 tissues in the intact plant. .
