This new series will cover all aspects of research on plant-microbe interactions, including beneficial plant symbioses such as symbiotic nitrogen fixation, plant pathology, plant genetics, molecular biology, agronomy, ecology, and phytochemistry. Over the past several years there has been a tremendous increase in our knowledge of plant-microbe relationships other than the Agrobacterium tumefaciens-crown gall complex and the nitrogen-fixing activites of Rhizobium species. The classical plant science disciplines (agronomy, breeding plant physiology, and systematics) in general have been strongly impacted by plant molecular biology, and concerns about environmental issues have also influenced the development of this new research. The Plant-Microbe Interactions Series will be of particular interest to professional researchers and graduate students interested in the interactions between bacteris and plants, including on the beneficial side nitrogen fixation and mycorrhizal associations, and on the other side interactions between plants and microbial pathogens. Plant molecular biologists and biotechnologists, and plant pathologists will also find this a valuable series.
