Project description:Dynamic cell identities underlie flexible developmental programs. The stomatal lineages in the Arabidopsis leaf epidermis feature asynchronous and indeterminate divisions that can be modulated by environmental cues. The products of these lineages, stomatal guard cells and pavement cells, regulate plant-atmosphere exchanges, and the epidermis as a whole influences overall leaf growth. How flexibility is encoded in development of the stomatal lineage, and how cell fates are coordinated in the leaf are open questions. Here, we offer single-cell transcriptomes to uncover models of cell differentiation within Arabidopsis leaf tissue.

Project description:Developmental transitions can be described in terms of morphology and individual genes expression patterns, but also in terms of global transcriptional and epigenetic changes. Most of the large-scale studies of such transitions, however, have only been possible in synchronized cell culture systems. Here we generate a cell type specific transcriptome of an adult stem-cell lineage in the Arabidopsis leaf using RNA sequencing and microarrays. RNA profiles of stomatal entry, commitment, and differentiating cells, as well as of mature stomata and the entire aerial epidermis give a comprehensive view of the developmental progression.

Project description:Identifying interaction partners and protein complex compositions for transcription factors (TFs) can produce valuable information on the mechanisms by which they regulate gene expression or are themselves regulated by signaling pathways in the cell. FAMA is a TF that is specifically expressed in the last stages of stomatal guard cell development in the epidermis of young leaves and other aerial tissues of higher plants. It is a master regulator of guard cell development and promotes terminal differentiation of the guard cell precursor by both activating and repressing hundreds of genes. How this is achieved mechanistically is still unclear. We therefore isolated putative FAMA interaction partners from young Arabidopsis seedlings expressing FAMA-CFP under the FAMA promoter using proteasome inhibitor treatment and formaldehyde crosslinking, followed by a classical co-immunoprecipitation mass spectrometry approach. Plants expressing nuclear GFP under a stomatal lineage specific promoter were used as controls. In two independent experiments with different crosslinking and immunoprecipitation conditions, we found ICE1, a known heterodimerization partner of FAMA, to be enriched in FAMA-CFP versus control samples. Other proteins with known transcriptional regulator or co-regulator function were not identified, presumably due to the low abundance of the bait protein. The interaction of FAMA with BRXL2, another regulator of guard cell development, which was detected in one experiment, is likely an artifact since BRXL2 does not localize to the nucleus under normal conditions.

Here we generate a cell type specific transcriptome of an adult stem-cell lineage in the Arabidopsis leaf using RNA sequencing and microarrays. RNA profiles of stomatal entry, commitment, and differentiating cells, as well as of mature stomata and the entire aerial epidermis give a comprehensive view of the developmental progression. To obtain pure cell populations corresponding to different stomatal lineage cell types we used Fluorescent Activated Cell Sorting (FACS) in combination with markers of early (SPCHp::SPCH-YFP, SSY), middle (MUTEp::nucGFP, MG), and late (FAMAp::GFP-FAMA, FGF) precursor stages, as well of mature stomata (enhancer trap E1728::GFP, E1728G) and a marker of the entire epidermis (ML1p::YFP-RCI2A, ML1Y). To minimize transcriptional differences due to age, all cell types were sorted from 14-day old aerial rosettes, and the specificity of expression pattern at this common time point confirmed via confocal microscopy. Total RNA was extracted from purified protoplasts (2,000 to 20,000 cells/replicate; 3 replicates/marker line) and transcript abundance measured using ATH1-121501 microarrays.
