TranscriptomicsMolecular Dissection of Pea Shoot Apical Meristem
Knowledge about an organism’s cell and tissue-specific transcriptional repertoire is essential for understanding the gene regulatory circuits that control key developmental events. The shoot apical meristem (SAM) is responsible for development of all the above ground parts of plants. Our underst...

TranscriptomicsTranscript profiling of the pea shoot apical meristem highlights processes underlying its function and maintenance
Plant growth is the result of cell proliferation in the meristems, which requires a dynamic balance between the formation of new tissue and the maintenance of a set of undifferentiated stem cells. There is much that remains unknown about this vital developmental process. In this study, we have repor...

TranscriptomicsArabidopsis AGO1 and AGO10 bound sRNAs
The shoot apical meristem (SAM) comprises a group of undifferentiated cells that divide to maintain the plant meristem and also give rise to all shoot organs. SAM fate is specified by class III HOMEODOMAIN-LEUCINE ZIPPER (HD-ZIP III) transcription factors, which are targets of miR166/165. In Arabido...

ProteomicsProteome of rice shoot apical meristem
DNA methylation is an epigenetic modification that specifies the basic state of pluripotent stem cells and regulates the developmental transition from stem cells to various cell types. In flowering plants, the shoot apical meristem (SAM) contains a pluripotent stem cell population which generates th...

TranscriptomicsTranscription profiling of Arabidopsis thaliana shoot apical meristem stem cell niche
A gene expression map of Arabidopsis thaliana shoot apical meristem stem cell niche was generated by isolating the specific cell type using the cell sorting methods. We used ap1-1;cal1-1 mutant background to enrich the sufficient number of cells for microarray analysis. Spatial and temporal regulat...

TranscriptomicsAnalysis of the effect of auxin biosynthesis inhibitor L-AOPP on the gene expression profile (shoot apical meristem)
Recently, 2-aminoxy-3-phenylpropionic acid (L-AOPP) had been demonstrated to possess an inhibitory activity against IAA biosynthesis but the molecular basis of the action was unclear. To investigate the function of L-AOPP, we conducted microarray analysis using the shoot apical meristem (SAM) part o...

TranscriptomicsAnalysis of the Arabidopsis shoot meristem transcriptome during floral transition identifies distinct regulatory patterns and an LRR protein that promotes flowering
We sequenced cDNA synthesized from mRNA from 3 time points of a time course of Arabidopsis thaliana shoot apical meristems. Plants were grown two weeks in short days (time point +0LD) and then exposed to long days for 1 day (time point +1LD) and 3 days (time point +3LD). Meristem cells were collecte...
