    Transport Gradient of Indoleacetic Acid in Pine Seedlings (1968)

    Notes: Movement of indoleacetic acid (IAA-1-14C) through 5-min segments from stems and roots of Pinus taeda L., P. jeffreyi Gtrev. and Balf., and P. ponderosa Laws, seedlings was measured. All three species showed the same general pattern of IAA-1-14C transport. Predominantly downward movement occurred at all points along the stem and root; least IAA-1-14C transport occurred in segments obtained near the shoot apex; and most occurred in segments obtained near or just below the cotyledons. This pattern of transport gradient is different from that reported in other plants. These results could be interpreted in either of two ways: (1) that transport limitations may control movement of the growth-regulator, or (2) that the transport gradient may be an indication of endogenous growth-regulator levels.

    Occurrence of trans -ribosylzeatin in Agrobacterium tumefaciens tRNA (1976)

    Notes: [Auszug] Four strains of A. tumefaciens were examined. Two strains, IIBV7 and C-58, are virulent and have been shown to harbour a large plasmid which is associated in some way with virulence8. The other two strains IIBNV6 and NT1, are avirulent and do not contain the plasmid. Strains C-58 and NT1 are very ...

    Trace enrichment of cytokinins from Douglas-fir xylem extrudate (1976)
    Springer
    Planta 131 (1976), S. 271-274 
    Details

    Topics: Biology
    Notes: Summary Quantitative trace-enrichment of cytokinins from a plant source (xylem sap from the Douglasfir, Pseudotsuga menziesii (Mirb.) Franco) has been achieved by adsorption onto octadecyl-silica columns followed by elution with ethanol. Adsorption is rapid and efficient and allows complete recovery of cytokinins at the nanomolar level. Douglas-fir sap contains at least four compounds having cytokinin activity, one of which co-elutes with zeatin and another with ribosylzeatin.
