In the quorum sensing-active state, the phytopathogenic Ralstonia pseudosolanacearum strain OE1-1 activates the 347-amino acid LysR-type transcriptional regulator PhcA, which regulates PhcA-regulated genes responsible for its virulence. To elucidate the functional role of the PhcA C-terminus, the phcA -deletion strain was transformed with a truncated phcA encoding PhcA lacking only the 20 C-terminal amino acids or a frameshift...

Processed aconite root (PA), the tuberous root of Aconitum carmichaelii prepared by autoclaving, is a crude drug used in Japanese traditional Kampo medicine and traditional Chinese medicine for the symptoms of kidney deficiency, that is related to the muscle atrophy in modern medicine. The objective of the present study is to evaluate the effectiveness of PA on muscle atrophy and to find its active ingredients using dexamethas...

Summary Isolation and functional analysis of microbes mediating the methylation of arsenic ( As ) in paddy soils is important for understanding the origin of dimethylarsinic acid ( DMA ) in rice grains. Here, we isolated from the rice rhizosphere a unique bacterium responsible for As methylation. Strain GSRB 54, which was isolated from the roots of rice plants grown in As ‐contaminated paddy soil under anaerobic conditions, wa...
