ePlant helps biologists visualize the natural connections between DNA sequences, natural variation (polymorphisms), molecular structures, protein-protein interactions, and gene expression patterns by combining several data visualization tools with a zoomable user interface.

ePlant connects to several publicly available web services to download the latest genome, interactome, and transcriptome data for any number of genes or gene products you may be interested in. Data is displayed with a set of visualization tools that are presented with a conceptual hierarchy from big to small. Links between the different views help underscore connections between multiple levels of analysis.

Seamlessly explore data from the kilometre to nanometre scales for Arabidopsis, including natural variation data, organ and cell-type-specific gene expression patterns, subcellular localization, protein-protein interactions, and protein tertiary structures predicted for ~70% of the proteome.

Expression Angler 2016 is a graphic user interface for our original Expression Angler. We have given the tool a complete UX makeover with the goal of making it easier to use.

This tool finds genes with similar expression patterns by calculating the correlation coefficients for all gene expression vectors as compared to an expression pattern that you define, or to an expression pattern associated with an AGI ID or gene name that you specify. The output of this tool displays an eFP image depicting the expression data and correlation coefficients for each gene that meets your cut-off criterion, or specified number of hits.

Legacy Expression Angler finds co-expressed, anti-correlated, or condition/tissue-specific genes in 5 of the data sets from the AtGenExpress Consortium, from our in-house database, or from NASCArrays. An example output image shows a selection of genes identified as co-expressed with ABI3 in the AtGenExpress Developmental Map data set from Detlef Weigel's group in Tübingen

This verson of the tool still works but we recommend using Expression Angler 2016instead.

Poplar Expression Angler finds co-expressed, anti-correlated, or condition/tissue-specific genes in two poplar data sets from the Campbell Laboratory.

Sampler Angler identifies samples exhibiting similar expression profiles, that is it will answer the question, 'which samples have the most similar expression profiles as the profile from my sample of interest?' Useful for chemical genomics or typing mutant tissues. Genes contributing the least or the most are highlighted in blue or red in the output scatterplot, shown as an example in this panel. In beta-testing, so feedback is welcome.

Perform electronic Northerns using the Expression Browser, i.e. ask how up to 125 genes of interest are being expressed, with the gene expression data sets accumulated to date in the Botany Array Resource (BAR) DB or public data sets from the AtGenExpress Consortium (Developmental - see the Schmid et al. publication, Abiotic Stress - Kilian et al. 2007, Pathogen, and Hormone Series), or others. Automatic clustering can be performed. Our databases contains more than 75 million expression measurements.

Make long sequence logos and zoom in and out of them with Gene Slider. Use the search panel to automatically highlight motifs of interest, even when there is a high degree of wobble. Slider controls for each position of a search query make it possible to assign certainty thresholds to control whether the search function will recognize partially conserved matches. A navigation slider at the bottom of the screen indicates which region of the sequence is currently being displayed. Coloured markers along this slider indicate where query motifs have been identified, making it easy to see where multiple matches have been found.
