Applications of Quantitative Microscopy in Studies of Plant Surface Microbiology

  • Frank B. Dazzo

Most of this chapter describes the author’s development and utilization of quantitative microscopy in studies of plant surface microbiology. The majority of this work has been done to gain a better understanding of the Rhizobium- legume root-nodule symbiosis.Various types of microscopy have been employed, including brightfield, phase-contrast, Nomarski-interference contrast, polarized light, real-time and time-lapse video, darkfield, conventional and laser scanning confocal epifluorescence, scanning electron, transmission electron, and field-emission scanning/transmission electron microscopies combined with visual counting techniques and manual interactive applications of image analysis.More recently, the author has led a team of scientists to develop a new generation of innovative, customized image analysis software designed specifically to analyze digital images of microbial populations and communities and extract all the informative, quantitative data of in situ microbial ecology from them at spatial scales relevant to the microbes themselves. We have begun to apply this new computer-assisted imaging technology to the fascinating field of plant surface microbiology. The chapter includes many figures that exemplify how the awesome resolving power of the microscope has significantly enhanced our understanding of plant surface microbiology, and richly illustrates how this topic area is even more enhanced with the added dimension of quantitation using computer-assisted digital image analysis.
