Emergence of a Synergistic Diversity as a Response to Competition in Pseudomonas putida Biofilms.

abstract：:> Abstract To determine if spatial variation in soluble carbon sources along the root coincides with different trophic groups of bacteria, copiotrophic and oligotrophic bacteria were enumerated from bulk soil and rhizosphere samples at 2 cm intervals along wheat roots 2, 3, and 4 weeks after planting. There was a mode...
