An approach to identification of specific components of the sorbose transport system in ungerminated conidia pretreated with sorbose is described here. The fact that sorbose stimulates sorbose-uptake without causing germination was exploited in differential labeling experiments. Sorbose treated and untreated conidia were incubated with (3H) -leucine and (14C) -leucine respectively, and then mixed extracts fractionated on CM-cellulose at pH 4.75. Changes in the 3H/14C-ratio indicated sorbose-induced or -repressed substances. In selecting labeling conditions, care was taken to avoid errors that might arise from any differences in the internal amino acid pool size. The investigation revealed a buffer-soluble component repressed by sorbose and a Triton-soluble component induced by sorbose. The buffer-soluble, sorbose repressible protein is discussed in connection with the phenomenon of sorbose toxicity in Neurospora. The Triton-soluble, sorbose stimulated component, probably of carotenoid nature, is considered as a possible constituent of the sorbose transport system investigated here.","PeriodicalId":23706,"journal":{"name":"Zeitschrift fur Naturforschung.

Before spreading each drop was examined by light microscopy and checked for purity. The outer segments were then either spread on the surface of a phosphotungstic acid solution (1.8 . . . 2.0%) containing 0 . 0 5 . . . 0.1% bovine serum albumin (pH 7.3) or negatively stained as drop preparations; instead of bovine serum albumin a 0.07% glycerol solution was also used. In contrast to micrographs of ultrathin sections (e.g. F E R N Ä N D E Z M O R Ä N 3 ; N I L S S O N 5 ) and previous negative staining experiments (BLASIE et al.2) which reveal \"dense granules\", \"globular substructures\" or \"particles ~ 4 0 Ä in diameter\" we found fibrillar elements (Fäden) in the outer segments as already postulated before on the basis of freeze-etching experiments (ROSENKRANZ 6 ) . In surface-spread and drop preparations we observed fibrils of different structure and diameter as well as partially preserved membranes. In preparations exposed to surface spreading we found predominantly well-spread, smooth fibrils (da). Their diameter is 49 Ä < da ^ 58 Ä, see Fig. 1 *. This wide range is due to the fact that several observers in our department made a total of 100 measurements from the same electron micrograph. Some micrographs indicate that each da-fibril might in turn be composed of fibrillar substructures.","PeriodicalId":23706,"journal":{"name":"Zeitschrift fur Naturforschung.
