(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) 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...

(Submitter supplied) Purpose: Identify SLGC cell fate by transcriptomes Methods: Cells expressing SLGC markers (BASLp:BRX-YFP, BASLp:myrBRX-YFP and myrBRXp:myrBRX-YFP) and stomatal commitment stage marker (MUTEp:MUTE-YFP) were collected by FACS. 9dpg plants were used for protoplasting and subjected to cell sorting. Around 20,000/sample were cellected and used for library preparation. Results: SLGCs are renriched in mitotic genes. 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) Lineage-specific stem cells are critical for the production and maintenance of specific cell types and tissues in multicellular organisms. In higher plants, the initiation and proliferation of stomatal stem cells is controlled by the basic helix-loop-helix transcription factor SPEECHLESS (SPCH). The stomatal stem cells and SPCH, which represent an innovation in seed plants, allow flexibility in the production of stomata, but how SPCH generates these stem cells is unclear. more...

(Submitter supplied) Our aim was to identify which stand alone amplification protocol performed best in our lab when the starting amount of total RNA was limited to 50 ng (A typical amount of total RNA we obtained by laser capture microdissection of tissues from silique samples). Since the quality of extracted RNA is very often tissue dependent and will affect the amplification efficiency, we decided to use total RNA extracted from whole siliques; better representing tissues targeted by LCM. more...

(Submitter supplied) Laser capture microdissection (LCM) provides a useful method for isolating specific cells or tissues from biological samples. Here, we adapted microdissection protocols to allow high-resolution transcript analysis of different tissues from developing Arabidopsis seed. However, to obtain enough RNA for microarray analyses it was necessary to amplify the RNA. Microarray analyses, using endosperm derived RNA amplified by two-round IVT, reproducibly identified endosperm enriched marker genes. more...

(Submitter supplied) Plant-specific DOF-type transcription factors regulate various biological processes. Here, we characterized a silique-abundant gene AtDOF4.2 for its functions in Arabidopsis. AtDOF4.2 is localized in the nuclear region and has transcriptional activation activity in both yeast and plant protoplast assays. The Thr-Met-Asp motif in AtDOF4.2 is essential for its activation. AtDOF4.2-overexpressing plants exhibit an increased branching phenotype, and the mutation of Thr-Met-Asp motif in AtDOF4.2 significantly reduces the branching in transgenic plants. more...
