• Sommario/riassunto: This book helps evaluate the state of the art of rhizosphere microbial ecology and biotechnology. Experts in the field review methods and strategies applied to the detection, identification and monitoring of microorganisms in the rhizosphere. Major topics treated include:- construction of genetically marked rhizosphere bacteria - detection of marked wildtype and genetically modified organisms (GMOs)- identification of wildtype and GMOs by DNA probes and PCR amplification- rapid typing of non-modified and GMOs by PCR-based techniques - assessment of the role of gene transfer
