TranscriptomicsTranscription profiling of Medicago truncatula root meristem cells
The root apical meristems (RAM) is established during embryogenesis and serves as a source of stem cells for plant growth and organogenesis. Young roots have a simple structure and meristeamtic and non-meristematic cells can be differentiated based on their location. We have used the Affymetrix Medi...

TranscriptomicsTranslatome analyses of opposing tissue-specific brassinosteroid signals orchestrating root meristem differentiation
The mechanisms ensuring balanced growth remain a critical question in developmental biology. In plants, this balance relies on spatiotemporal integration of hormonal signaling pathways, but the understanding of the precise contribution of each hormone is just beginning to take form. Brassinosteroid ...

TranscriptomicsThe CLE40 and CRN/CLV2 signaling pathways antagonistically control root meristem growth in Arabidopsis
Differentiation processes in the primary root meristem are controlled by several signaling pathways that are regulated by phytohormones or by secreted peptides. Long term maintenance of an active root meristem requires that the generation of new root meristem cells and the loss of cells from the mer...

TranscriptomicsExpression data of Soybean root apical meristem and leaf
we used soybean genome chips to investigate the expression pattern of about 37,500 unique ESTs locating on soybean Affymetrix chips (Affymetrix Inc.). KEYWORDS: Tissue comparison we compared soybean root meristem samples with non-meristematic tissues in 10 days old vegetative stage seedlings to defi...

MetabolomicsPb Stress and Ectomycorrhizas: Strong Protective Proteomic Responses in Poplar Roots Inoculated with Paxillus involutus Isolate and Characterized by Low Root Colonization Intensity
The commonly observed increased heavy metal tolerance of ectomycorrhized plants is usually linked with the protective role of the fungal hyphae covering colonized plant root tips. However, the molecular tolerance mechanisms in heavy metal stressed low-colonized ectormyocrrhizal plants characterized ...

TranscriptomicsTranscription profiling by array of Arabidopsis wild type and an ARF7/ARF19 double knockout mutant roots dissected into 5 developmental zones
Arabidopsis seedlings, of both wild-type and an ARF7/ARF19 double knockout mutant, were grown to 7 days post-germination. The roots were then dissected into 5 developmental zones, the meristem, early elongation zone, late elongation zone, mature root and lateral root zone. The sections then underwen...

TranscriptomicsEffects of drought on gene expression in Maize reproductive and leaf meristem tissue revealed by RNA-seq
Purpose: To study the effects of drought at the transcriptomic level on two different actively dividing maize tissue: the ovaries, and the leaf meristem Methods: The Illumina reads were mapped to the maize B73 reference genome using Tophat followed by transcriptome reconstruction using Cufflinks. T...

TranscriptomicsNodal Root Bud Development - Transcriptome Analysis
Bioenergy sorghum’s large and deep nodal root system and associated microbiome enables uptake of water and nutrients from and deposition of soil organic carbon into soil profiles, key contributors to the crop’s resilience and sustainability. The goal of this study was to increase our understanding o...

TranscriptomicsmicroRNA profiling of root tissues and root forming explant cultures in Medicago truncatula
To identify key miRNAs involved in root meristem formation in M. truncatula, deep sequencing was used to compare the miRNA populations dreived from four tissues. These were; root tip tissue, containing the root apical meristem, elongation zone tissue, root forming callus tissue and non-root formi...

TranscriptomicsCell- and tissue-specific transcriptome analyses of Medicago truncatula root nodules
We used laser-capture microdissection (LCM) to isolate specific cells from the Medicago truncatula nodule meristem (M), the distal infection (DIZ), the proximal infection zone (PIZ), infected cells (IC) and uninfected cells (UIC) from the fixation zone. Based on Medicago GeneChips, we identified the...
