Use of Bioluminescence Markers To Detect Pseudomonas spp. in the Rhizosphere.

abstract：:Small streams and their headwaters are key sources of microbial diversity in fluvial systems and serve as an entry point for bacteria from surrounding environments. Community assembly processes occurring in these streams shape downstream population structure and nutrient cycles. To elucidate the development and stabil...
