TranscriptomicsOverexpression of NtmybA2 in tobacco BY-2 cells
Promoters of many G2/M phase-specific genes in plants contain mitosis-specific activator (MSA) elements, which act as G2/M phase-specific enhancers and bind with R1R2R3-Myb transcription factors. A least three R1R2R3-Myb proteins are expressed in tobacco (Nicotiana tabacum). To examine the genome-wi...

TranscriptomicsCell cycle-regulated gene expression in tobacco cells
Tobacco BY-2 cells can be highly synchronized by treatment with an inhibitor of DNA synthesis, aphidicolin. For comprehensive understanding of cell cycle-regulated gene expression in tobacco, microarray analysis was conducted in synchronized cultures of BY-2 cells. Cells were treated with aphidicoli...

TranscriptomicsContribution of NAC transcription factors to plant adaptation to land
The development of cells specialized for water conduction or support is a striking innovation of plants that has enabled them to colonize land. The NAC transcription factors regulate differentiation of these cells in vascular plants. However, the path by which plants with these cells have evolved fr...

TranscriptomicsTranscriptional profiling of leaf blades and petioles subjected to shade avoidance syndrome
Plants grown under a canopy recognize changes in light quality and modify their growth patterns; this modification is known as shade avoidance syndrome. In leaves, leaf blade expansion is suppressed, whereas petiole elongation is promoted under the shade. However, the mechanisms that control these r...

TranscriptomicsCYTOKININ HYPERSENSITIVE1 (CKH1) and CKH2 affect to cytokinin responses in tissue culture
Analysis of calli derived from the wild type (Ler), the ckh1 and ckh2 mutants cultured on media in the absence of cytokinin (control), in the presence of low (25 ng/ml kinetin) or high (200 ng/ml kinetin) levels of cytokinin, or in the presence of Trichostatin A (TSA). In these conditions, a constan...

TranscriptomicsFinding direct target genes of VND7
Direct target genes of VND7 were explored with inducible expression system using glucocorticoid receptor (GR). Transgenic plants expressing 35S:VND7-VP16-GR were treated with dexamethazone (DEX) and/or protein synthesis inhibitor cycloheximide (CHX). A number of genes related to the formation of vas...

TranscriptomicsTranscription profiling by array of Arabidopsis transgenic plants overexpressing YFP and VND7-YFP
The Arabidopsis thaliana NAC domain transcription factor, VASCULAR-RELATED NAC-DOMAIN7 (VND7), acts as a master regulator for differentiation of xylem vessels. In order to identify a set of genes regulated by VND7, we carried out a microarray experiment with the Arabidopsis full-genome GeneChip arra...

TranscriptomicsExpression data from Arabidopsis myb3r mutants
Temporal and spatial regulation of cell division is central for generating multicellular organs with predictable sizes and shapes. However, it remains largely unclear how genes with mitotic functions are transcriptionally regulated during organogenesis in plants. Here, we showed that a group of R1R2...

TranscriptomicsTranscriptomic analysis of the myb3r1 myb3r4 double mutant in Arabidopsis thaliana
R1R2R3-Myb proteins represent an evolutionarily conserved class of Myb family proteins important for cell cycle regulation and differentiation in eukaryotic cells. In plants, this class of Myb proteins are believed to play important roles in cell cycle regulation through transcriptional regulation o...

no omics definedTranslation profiling of Arabidopsis cell cultures exposed to elevated temperature and high salinity
We investigated genome-wide changes in mRNA translation in Arabidopsis thaliana suspension cell cultures exposed to brief perids of two types of stress: elevated temperature (37 degree_C) and high salinity (200 mM NaCl). To this end, we subjected polysomal RNA and non-polysomal RNA from sucrose grad...
