TLDR
Genevestigator as mentioned in this paper is a web-browser interface for gene expression analysis using Affymetrix GeneChip data, which allows users to retrieve the expression patterns of individual genes throughout chosen environmental conditions, growth stages, or organs.Abstract:
High-throughput gene expression analysis has become a frequent and powerful research tool in biology. At present, however, few software applications have been developed for biologists to query large microarray gene expression databases using a Web-browser interface. We present GENEVESTIGATOR, a database and Web-browser data mining interface for Affymetrix GeneChip data. Users can query the database to retrieve the expression patterns of individual genes throughout chosen environmental conditions, growth stages, or organs. Reversely, mining tools allow users to identify genes specifically expressed during selected stresses, growth stages, or in particular organs. Using GENEVESTIGATOR, the gene expression profiles of more than 22,000 Arabidopsis genes can be obtained, including those of 10,600 currently uncharacterized genes. The objective of this software application is to direct gene functional discovery and design of new experiments by providing plant biologists with contextual information on the expression of genes. The database and analysis toolbox is available as a community resource at https://www.genevestigator.ethz.ch.read more

Tyrosine and Phenylalanine Are Synthesized within the Plastids in Arabidopsis
TL;DR: Analysis of the subcellular localization of the two TYRAAts and the six AtADTs eliminated the possibility of Tyr and/or Phe synthesis within the cytosol, at least in green leaves and Arabidopsis cultured cells.

The arabidopsis zinc finger-homeodomain genes encode proteins with unique biochemical properties that are coordinately expressed during floral development
TL;DR: It is proposed that the zinc finger-homeodomain (ZF-HD) gene family encodes a group of transcriptional regulators with unique biochemical activities that play overlapping regulatory roles in Arabidopsis floral development.

Post-transcriptional RNA silencing in plant-microbe interactions: a touch of robustness and versatility
TL;DR: These studies simultaneously unravel a staggering degree of complexity and flexibility in endogenous RNA silencing pathways, a likely reflection of the plants' faculty to adapt to their environment.

Arabidopsis thaliana T-DNA Mutants Implicate GAUT Genes in the Biosynthesis of Pectin and Xylan in Cell Walls and Seed Testa
TL;DR: The wall glycosyl residue compositional phenotypes observed among the gaut mutants suggest that at least six different biosynthetic linkages in pectins and/or xylans are affected by the lesions in these GAUT genes.

PSK-α promotes root growth in Arabidopsis
Anke Kutschmar,Guillaume Rzewuski,Nils Stührwohldt,Gerrit T.S. Beemster,Gerrit T.S. Beemster,Dirk Inzé,Margret Sauter +6 more
TL;DR: The results indicate that PSK-α signaling through AtPSKR1 affects root elongation primarily via control of mature cell size, while Root organogenesis, on the other hand, is not controlled by PSk-α.

Gene Expression Omnibus: NCBI gene expression and hybridization array data repository
TL;DR: The Gene Expression Omnibus (GEO) project was initiated in response to the growing demand for a public repository for high-throughput gene expression data and provides a flexible and open design that facilitates submission, storage and retrieval of heterogeneous data sets from high-power gene expression and genomic hybridization experiments.

Analysis of the genome sequence of the flowering plant Arabidopsis thaliana.
TL;DR: This is the first complete genome sequence of a plant and provides the foundations for more comprehensive comparison of conserved processes in all eukaryotes, identifying a wide range of plant-specific gene functions and establishing rapid systematic ways to identify genes for crop improvement.

Expression monitoring by hybridization to high density oligonucleotide arrays
TL;DR: In this article, the authors proposed a method for monitoring the expression levels of a multiplicity of genes by hybridizing a nucleic acid sample to a high density array of oligonucleotide probes and quantifying the hybridized nucleic acids in the array.
Journal ArticleDOI
Hierarchical Organization of Modularity in Metabolic Networks
TL;DR: It is shown that the metabolic networks of 43 distinct organisms are organized into many small, highly connected topologic modules that combine in a hierarchical manner into larger, less cohesive units, with their number and degree of clustering following a power law.
