چکیده
tion3’ n ’ 22 wird durch diesen Stoffwechselweg ge deckt. Die sog. Shikimisäure-Prephensäure-Sequenz — ohne den Pentosephosphatzyklus-Vorspann nicht denkbar — ist Voraussetzung zur Bildung vieler aromatischer Verbindungen, die im Wundgewebe intensiv hergestellt werden 23. Auch werden Pentosederivate in die Histidin24 und Tryptophan-Syn these 25 einbezogen, was u. a. für die wundbedingte IES-Synthese von Bedeutung sein könnte. Das im Pentosezyklus gebildete NADPH ist für die im Wundgewebe nachgewiesene Fettsäuresyn these erforderlich. Darüber hinaus setzt die Protein synthese des Kartoffelwundgewebes eine ausreichende Menge an Aminosäuren voraus, deren Konzentra tion während der anfänglichen Phase der Wundhei lung stark verringert wird 26.

Isolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy
Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...
متن کاملSCALE FORMATION IN CHRYSOPHYCEAN ALGAE I . Cellulosic and Noncellulosic Wall Components Made by the Golgi Apparatus
The cell wall of the marine chrysophycean alga Pleurochrysis scherfellii is composed of distinct wall fragments embedded in a gelatinous mass . The latter is a polysaccharide of pectic character which is rich in galactose and ribose . These wall fragments are identified as scales . They have been isolated and purified from the vegetative mother cell walls after zoospore formation . Their ultras...
متن کاملSize, shape, and arrangement of native cellulose fibrils in maize cell walls
Higher plant cell walls are the major source of the cellulose used in a variety of industries. Cellulose in plant forms nanoscale fibrils that are embedded in non-cellulosic matrix polymers in the cell walls. The morphological features of plant cellulose fibrils such as the size, shape, and arrangement, are still poorly understood due to its inhomogeneous nature and the limited resolution of th...
متن کاملVisualization of biomass solubilization and cellulose regeneration during ionic liquid pretreatment of switchgrass.
Auto-fluorescent mapping of plant cell walls was used to visualize cellulose and lignin in pristine switchgrass (Panicum virgatum) stems to determine the mechanisms of biomass dissolution during ionic liquid pretreatment. The addition of ground switchgrass to the ionic liquid 1-n-ethyl-3-methylimidazolium acetate resulted in the disruption and solubilization of the plant cell wall at mild tempe...
