摘要:

Use of Aphids for sampling the cell sap of Cuscuta epithymum. —A variety of Myzus persicae that feeds specifically on Cuscuta epithymum has been employed in a study of the translocation of nutrilites from the host, Trifolium repens,to the parasite, C.epithymum.If the host was exposed to an atmosphere containing C14,O2, the Aphids feeding on the Cuscuta filaments became labelled very rapidly and to considerable extent. The analysis of the distribution of radioactivity in theCuscutafilaments and the Aphids revealed that extensive degradation of the compounds and randomization of the label occurred in the insects.

摘要:

Uptake of metabolites byCUSCUTA. —The distribution of the radioactivity in the filaments of Cuscuta epithymum attached to the host(Trifolium repens)growing in an atmosphere of C14O2indicates that the dodder uptakes from the host solely, or mainly, sucrose. The other radioactive compounds present in the extracts of Cuscuta appear to be derived from the sucrose rather than uptaken from the host.

摘要:

The effect of colchicine on sulfhydryl enzymes. —The effect of colchicine has been tested on mithocondrial ATPase and rat-liver LDH. The colchicine inhibits ATPase for 40% and LDH for 100%, therefore its action is aspecific.
