Phosphate starvation promoted the accumulation of phenolic acids by inducing the key enzyme genes in Salvia miltiorrhiza hairy roots.

Phosphate starvation increased the production of phenolic acids by inducing the key enzyme genes in a positive feedback pathway in Saliva miltiorrhiza hairy roots. SPX may be involved in this process. Salvia miltiorrhiza is a wildly popular traditional Chinese medicine used for the treatment of coronary heart diseases and inflammation.

[Diversity of antagonistic bacteria isolated from rhizosphere of several cash crops].

By adopting antimicrobial spectrum test, BOXAIR-PCR, physiological and biochemical, and 16S rDNA sequencing analysis, this paper analyzed the diversity of 55 antagonistic bacterial strains isolated from the rhizosphere of 10 cash crops. There was a high diversity of the antagonism of the strains. Based on BOXAIR-PCR, all the strains were clustered into 7 groups at the similarity level of 72.

[Cloning and functional analysis of cysI gene involved in siderophores biosynthesis in Pseudomonas mosselii E1].

A siderophores-producing strain E1 was isolated from the rhizosphere of cotton. Its 16S rDNA is identical to that of Pseudomonas mosselii sp. nov.
