(Submitter supplied) Analysis of gene expression in Arabidopsis thaliana leaf, stem and flower tissues. Columbia (Col-0) Arabidopsis thaliana plants were grown at a density of 4 plants per 5 inch square pot either in a growth chamber or a green house set to 25*C by day, 20*C by night. Days were set to a 16hr photoperiod with 125 micro mol m-2s-1 fluorescent irradiation. Expanding leaves were harvested 15 days post germination in the middle of the photoperiod (3 replicates). more...

Examination of gene expression in 7 days post-germination seedlings with either an inactive or a constitutively active YODA MAPKK. Inactivating YODA results in excess stomata, and constitutively activating YODA eliminates stomata.

(Submitter supplied) 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. more...

(Submitter supplied) We initiated a study to investigate the transcriptional profiles associated with cell states of the stomatal lineage. A stem-cell like precursor of stomata, a meristemoid. reiterates asymmetric divisions and renews itself before differentiating into guard cells. The transient and asynchronous nature of the meristemoid has made it difficult to study its molecular characteristics. Through combinatorial use of genetic resources that either arrest or constitutively drive stomatal cell-state progressions due to loss- or gain-of-function mutations in the key transcription factor genes, SPEECHLESS, MUTE, and SCRM, we obtained seedlings highly enriched in pavement cells, meristemoids, or stomata. more...

(Submitter supplied) In plants, formation of functional stomatal guard cells is a highly regulated event so that this cell differentiation model constitutes an interesting genetic system to explore cell differentiation in response to cell cycle controllers or cell fate determinants such as transcription factors. The latest acting bHLH in the stomatal lineage circuit is FAMA that appears to be absolutely required to promote stomatal development by controlling the GMC to GC transition. more...

(Submitter supplied) 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. more...

(Submitter supplied) Wild type and yda-2 plants were germinated and grown on commercial potting mix in walk-in chambers with constant illumination (~150 micromoles per square meter per second) at 22oC. The aerial parts of the plants were harvested at the rosette stage, prior to bolting. Total RNA was prepared using Trizol reagent (Invitrogen) with the additional steps recommended for polysaccharide-rich tissues. Hybridization probes for the GeneChip AtGenome1 microarrays (Affymetrix) were prepared from 20 mg total RNA. more...

(Submitter supplied) The Arabidopsis thaliana defense regulator EDM2 was previously shown to be specifically required for disease resistance to the pathogenic oomycete Hyaloperonospora parasitica aradidopsis mediated by the R protein RPP7. We found EDM2 to have a promoting effect on several distinct developmental processes, such as leaf pavement cell development, vegetative phase change or the floral transition. We further identified the atypical protein kinase WNK8 to physically interact with EDM2 in nuclei. more...

(Submitter supplied) Precise cell division control is critical for developmental patterning. For the differentiation of a functional stoma, a cellular valve for efficient gas exchange, the single symmetric division of an immediate precursor is absolutely essential. Yet, the mechanism governing the single division event remains unclear. Here we report the complete inventories of gene expression by the Arabidopsis bHLH protein MUTE, a potent inducer of stomatal differentiation. more...

(Submitter supplied) We have previously identified genes that are induced by MUTE, key transcription factor for stomatal lineage fate commitment and symmetric cell division that create stomata surrounded by a pair of guard cells in Arabidopsis. To test whether these genes are indeed direct MUTE targets, we performed genome-wide MUTE ChIP-sequencing.

(Submitter supplied) The root epidermis of Arabidopsis provides a simple and experimentally useful model for studying the molecular basis of cell fate and differentiation. The goal of this study was to define the transcript changes in the root epidermis of mutants associated with root epidermis cell specification, including mutants that lack a visible phenotypic alteration (try, egl3, myb23, and ttg2). Transcript levels were assessed by purifying populations of root epidermal cells using fluorescence-based cell-sorting with the WER::GFP transgene. more...
