Abstract
Fluorescence-activated cell sorting (FACS) is a powerful method for the analysis of cell type-specific transcriptome profiles, DNA or histone modifications, and chemical compounds. In plants, it has been employed mainly with root and shoot tissue in combination with cell wall digestion on cellular and nuclear content. However, many tissues are recalcitrant to cell separation and are therefore not readily accessible for FACS analysis. Here, we lay out a detailed protocol for the generation of transcriptional profiles from fluorescently labeled nuclei. The protocol described in this chapter has been used successfully to generate a transcriptional map of the early Arabidopsis thaliana embryo.
