Nitrous oxide (N2O) emissions from grazing animal excreta are estimated to be responsible for 1.5 Tg of the total 6.7 Tg of anthropogenic N2O emissions. This study was conducted to determine the in situ effect of incorporating biochar, into soil, on N2O emissions from bovine urine patches and associated pasture uptake of N. The effects of biochar rate (0-30(More)
Chicken erythrocyte chromatins containing a single species of linker histone, H1 or H5, have been prepared, using reassembly techniques developed previously. The reconstituted complexes possess the conformation of native chicken erythrocyte chromatin, as judged by chemical and structural criteria; saturation is reached when two molecules of linker histone(More)
Yields from wheat (Triticum aestivum L.) cultivars grown in natural soils and soils inoculated with Gaeumannomyces graminis var. tritici (Ggt), the fungus causing take-all, were obtained in separate second-year wheat fields over three successive growing seasons in Canterbury, New Zealand. Cultivars ‘Empress’, ‘Oakley’, ‘Phoenix’ and ‘Sage’ were compared(More)
We have isolated a crude nuclear preparation from the unicellular red alga Porphyridium aerugineum and investigated the structure of Porphyridium chromatin. Electrophoresis of deproteinized DNA fragments produced by micrococcal nuclease digestion of Porphyridium nuclei gives a typical ladder pattern, indicative of a repeating structure. The DNA(More)
