Methods in Rhizosphere Biology Research

Prof. D. Reinhardt is a researcher at the University of Fribourg, Switzerland. After completing his doctoral studies in the field of plant-pathogen interactions at the University of Basel, and a postdoc stay at the Salk Institute in La Jolla (California), he worked at the University of Bern. His main area of interest encompasses various aspects of arbuscular mycorrhizal symbiosis, with particular emphasis on the genetic factors in the host required for the intracellular accommodation of the fungal symbiont, and on the regulation of AM by exogenous factors such as nutrient availability. In addition, Prof. Reinhardt is currently investigating organ formation and regulation of the body plan of plants. This includes the positioning of leaves and flowers around the growth axis, a phenomenon known as phyllotaxis. He has published over 50 research and review articles in various scientific journals. Prof. Anil Kumar Sharma is a Professor at the Department ofBiological Sciences, CBSH G.B. of Pant University of Agriculture & Technology in Pantnagar. He completed his postdoctoral studies at the GSU, Louisiana (USA), and has been a Visiting Scientist at the University of Basel, Switzerland (2003) and University of Helsinki, Finland (2013). He has extensive research and teaching experience, and served as a reviewer for various funding bodies and international research journals. He also holds two patents in plant biology and microbiology, respectively. The recipient of various prestigious grants, he has published more than 60 research articles and 30 review articles, as well as two books with prominent publishers.
