MetabolomicsStress-related mitogen-activated protein kinases stimulate the accumulation of small molecules and proteins in Arabidopsis thaliana root exudates
A delicate balance in cellular signaling is required for plants to distinguish mutualist from parasitic organisms in its environment. Mitogen-activated protein kinase (MAPK) cascades are one of the signaling modules that mediate transduction of extracellular microbial signals into appropriate cellul...

MetabolomicsPlant-to-plant variability in root metabolite profiles of 19 Arabidopsis thaliana accessions is substance-class dependent
Natural variation of secondary metabolism between different accessions of Arabidopsis thaliana has been studied extensively. In this study, we extended the natural variation approach by including biological variability and analyzed root metabolic patterns as well as their variability between plants ...

TranscriptomicsExpression data from Arabidopsis wild type and ibr1 ibr3 ibr10 triple mutant seedlings root tip segments treated with indole-3-butyric acid (IBA)
The root cap-specific conversion of the auxin precursor indole-3-butyric acid (IBA) into the main auxin indole-3-acetic acid (IAA) generates a local auxin source which subsequently modulates both the periodicity and intensity of auxin response oscillations in the root tip of Arabidopsis, and consequ...

TranscriptomicsTranscriptome analysis of rice roots and tips in early development by massive parallel sequencing
Despite the major physiological dissimilarities between roots and their tips, differences in their gene expression profiles remain largely unexplored. In this research, the transcriptome of rice (Oryza sativa L. subsp. Japonica) mature root tissue and root tips was monitored using mRNA-Seq at 2 time...

ProteomicsImpact of nitrate on the proteome of the primary root tip of Medicago truncatula
The impact of nitrate on the proteome of the primary root tip of Medicago truncatula were compared in R108, a wild and sensitive genotype, and npf6.8, a mutant and insensitive line by shotgun analysis. Each genotype were cultivated in N-free condition or with 5mM of nitrate in three independent biol...

Transcriptomicstranscripomics on the arabidopsis root tip during phosphate starvation-Transcripomics on the Arabidopsis Root tip during phosphate starvation
The objective of this project is to identify genes that are expressed in the Arabidopsis thaliana root tip and that are early induced (or repressed) by phoshate deficiency. Seedlings were germinated and grown (for 6 days) on phosphate rich medium and transfered to either a phosphate poor medium (Pi-...

TranscriptomicsCellular and gene expression patterns associated with root bifurcation in Selaginella
To identify possible molecular mechanisms with a role in root branching initiation in S. moellendorffii, we employed the developmental root branching assay for an RNA-seq experiment and sampled root tips on each day from 0 to 5 d after the first branching (time point 0), in which 300 µm apical parts...

TranscriptomicsGene expression in Maize root region 1 at low water potential
Previous work showed that the maize primary root adapts to low water potential (-1.6 MPa) by maintaining longitudinal expansion in the apical 3 mm (region 1), whereas in the adjacent 4 mm (region 2) longitudinal expansion reaches a maximum in well-watered roots but is progressively inhibited at low ...

TranscriptomicsA study of transcriptome response to salt treatment across three zones of the root in a barley landrace and malting cultivar
Paired-end RNA-Seq libraries were constructed for three root sections of the roots of barley cv. Clipper, and landrace Sahara, grown under control and salt-treated (100 mM NaCl) conditions on agar plates in quadruplicate. Experiments were conducted in a temperature-controlled growth cabinet at 17 C ...
