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

TL;DR: In this paper, the role of DNA polymerase e during gametophyte and seed development using forward and reverse genetic approaches was investigated in Arabidopsis, where the catalytic subunit of this complex is encoded by two genes, AtPOL2a and AtDP2b, whereas the second largest regulatory subunit AtDPB2 is present as a unique complete copy.

Genome-wide analysis of the GH3 family in apple (Malus × domestica).
TL;DR: This study indicated that some GH3 genes were significantly induced in M. sieversii after various phytohormone and abiotic stress treatments, and that ABA, SA, salt, and cold treatments reduce the endogenous level of axuin.

Mutation of Arabidopsis BARD1 Causes Meristem Defects by Failing to Confine WUSCHEL Expression to the Organizing Center
Pei Han,Qing Li,Yu-Xian Zhu +2 more
TL;DR: It is suggested that BARD1 regulates SAM organization and maintenance by limiting WUS expression to the organizing center and either full-length Bard1 or a clone that encoded the C-terminal domain was sufficient to complement the bard1-3 phenotype.

Characterization of a small auxin-up RNA (SAUR)-like gene involved in Arabidopsis thaliana development.

TL;DR: The root of Arabidopsis thaliana is used as a model system to unravel the molecular nature of cell elongation and its arrest and it is concluded that the expression of SAUR76 is mainly regulated by the increase in auxin that results from the addition of ACC, rather than by ACC itself.

The arginine decarboxylase gene ADC1, associated to the putrescine pathway, plays an important role in potato cold-acclimated freezing tolerance as revealed by transcriptome and metabolome analyses
Shuang Kou,Lin Chen,Lin Chen,Wei Tu,Federico Scossa,Federico Scossa,Yamei Wang,Jun Liu,Alisdair R. Fernie,Botao Song,Conghua Xie +10 more
TL;DR: The present research has identified that the ADC1-associated putrescine pathway plays an important role in cold-acclimated freezing tolerance of potato, probably by enhancing the expression of CBF genes.

TL;DR: The goal of the Gene Ontology Consortium is to produce a dynamic, controlled vocabulary that can be applied to all eukaryotes even as knowledge of gene and protein roles in cells is accumulating and changing.

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.
