Updates on Rhizobacteria captures in a single volume the wealth of information about the presence, appearance, function, and utilization of rhizobacteria. Rhizobacteria play critical roles in nutrient acquisition and assimilation, improvement of soil texture, and the secretion and modulation of extracellular molecules such as hormones, secondary metabolites, antibiotics, and various signal compounds, all of which lead to enhanced plant growth and development. Rhizobacteria are also integral to plant-microbe interactions and for modulating plant stress responses. Updates on Rhizobacteria is a useful resource for instructors and students in advanced undergraduate and graduate courses on rhizobacteria. It is also valuable for researchers seeking new relationships between biological processes that are linked by rhizobacteria and the environment.
