Live cell imaging has tremendously promoted our understanding of cellular and subcellular processes such as cell division. Here, we present a step-by-step protocol for a robust and easy-to-use live cell imaging approach to study male meiosis in the plant as recently established. Our method relies on the concomitant analysis of two reporter genes that highlight chromosome configurations and microtubule dynamics.

- Plant development is generally consistent, but some variability exists due to noisy gene expression.
- Using Arabidopsis thaliana and a special marker, researchers found that protein expression in individual cells changes over time.
- They discovered that extrinsic noise (variation from external factors) is greater than intrinsic noise (variation within the gene), with stomata exhibiting lower extrinsic noise compared to other tissues, and demonstrated that younger plant cells show interconnected stochastic behavior in protein expression, unlike mature leaves.
