Early plant embryogenesis condenses the fundamental processes underlying plant development into a short sequence of predictable steps. The main tissues, as well as stem cells for their post-embryonic maintenance, are specified through genetic control networks. A key question is how cell fates are instructed by unique cellular transcriptomes, and important insights have recently been gained through cell type-specific transcriptomics during post-embryonic development. However, the poor accessibility and small size of <em>Arabidopsisem> (<em>Arabidopsis thalianaem>) embryos have obstructed similar progress during embryogenesis. Here, we review the current situation in plant embryo transcriptomics, and discuss how the recent development of novel cell-specific analysis technologies will enable the identification of cellular transcriptomes in the early <em>Arabidopsisem> embryo.
