The bioluminescent reporter system is a powerful tool for the long-term monitoring of gene expression because of its noninvasive nature. Furthermore, in combination with high-sensitive imaging technology, spatiotemporal analysis on regulation and heterogeneity in gene expression is possible. We developed a single-cell bioluminescent imaging system for plants through a transient gene transfection by particle bombardment. By applying this system to a duckweed species, we succeeded in monitoring circadian rhythms of individual cells in an intact plant for over a week. Here we describe methods for gene transfection by particle bombardment and single-cell bioluminescence monitoring by a high-sensitive camera. This technique provides a platform for characterizing gene expression patterns of individual cells in the same tissue.
