Development is a dynamic process occurring at the microscopic scale. The ability to see
how it unfolds in detail is invaluable not only for helping us appreciate its full complexity but
also to experimentally dissect its mechanisms. The sophistication of experimental
approaches and imaging technologies has increased over the past decade at an astounding
pace. In this review we highlight and discuss several studies that illustrate the latest
advances in the application of live-imaging to dissect plant development.
