Characterization and Metabolism Effect of Seed Endophytic Bacteria Associated With Peanut Grown in South China.

abstract：:Streptococcus mutans is an important pathogen in the human oral biofilm. It expresses virulent behaviors that are linked to its genetic competence regulon, which is controlled by comX. Expression of comX is modulated by two diffusible signaling peptides, denoted CSP and XIP, and by other environmental cues such as pH ...
