1. Radioactivity from d-[l-(14)C]glucosamine is incorporated into ethanol-insoluble compounds of high molecular weight in a number of plant tissues, including roots of corn (Zea mays), callus cells of sycamore (Acer pseudoplatanus), axenic cultures of duckweed (Lemna minor) and germinating seedlings
Histones were extracted from chromatin of the following: a moss (Polytrichum juniperinum); the primitive vascular plants Psilotum nudum and Equisetum arvense; a fern (Polypodium vulgare); the gymnosperms fir (Abies concolor), yew (Taxus canadensis) and Gingko biloba; the dicotyledonous angiosperms
A non-reducing trisaccharide, alpha-D-mannopyranosyl-(1 --> 4)-alpha-D-glucuronopyranosyl-(1 --> 2)-myo-inositol (MGI) accumulated in the spent medium of cell-suspension cultures of 'Paul's Scarlet' rose (Rosa sp.) predominantly during the period of rapid cell growth. This trisaccharide was also
Headwater streams draining agricultural landscapes receive maize leaves (Zea mays L.) via wind and surface runoff, yet the contribution of maize detritus to organic-matter processing in agricultural streams is largely unknown. We quantified decomposition and microbial respiration rates on
