Rhizosphere is a textbook for microbial N cycle

Minamisawa, Kiwamu Graduate School of Life Sciences, Tohoku University The term “rhizosphere” was first coined in 1904 by Lorenz Hiltner in Germany, who had a special interest in N transformations around leguminous nodules in fields. Our group has revealed active N transformation incl

Regulation of N2O reductase genes by the two-component system NasST in Bradyrhizobium diazoefficiens

Sanchez, Cristina Graduate School of Life Sciences, Tohoku University, Japan The greenhouse gas nitrous oxide (N2O) is emitted from soybean rhizosphere through the degradation of the root nodules at the late growth period. Soybean hosts endosymbiotic N2-fixing soil bacteria (rhizobia)

Phylogenetic diversity and environmental distribution of denitrifying fungi

Sameshima-Saito, Reiko Shizuoka University Fungi are saprophytic organisms and play pivotal roles to degrade organic matter such as plant residue in soil ecosystems. Some fungi have been revealed to possess ability of nitrification and/or denitrification, and therefore the processes o

Isolation, physiology, and genomics of novel nitrifiers

Fujitani, Hirotsugu, Tsuneda, Satoshi Dept. of Life Sci. and Med. Biosci., Waseda Univ. After bacterial chemoautotrophy on nitrification was discovered by Sergei Winogradky more than a century ago, nitrification research developed steadily but with slow progress. Nitrification consist
