MaizeGGM gene network
MaizeGGM is a gene network for maize functional genomics studies. It was constructed using the graphical Gaussian modle (GGM), based on large scaled RNA-Seq data. The network contains 20,269 genes that assemble into 964 gene modules. These modules function in an array of maize development, nutrients uptake & utilization, metabolism, stress response, and cellular organization processes.The detailed information of this network are provided in this web-page, as listed below.
The MaizeGGM program (Click here to download)
This program, written in R, can be used to extract the gene modules’ information from the MaizeGGM network. The program’s major functions are: (A). Extracting sub-networks for genes of a specific module or for genes connected with a gene of interest. The extracted sub-networks can then be visualized to see how genes interact with each other. (B). Generating heatmaps for selected gene modules, showing their genes’ tissues-specific expression patterns.
Detailed information for every module within the network
For each module, a web-page was created to show the module’s detailed information, including the list of gene within the module, Gene Ontology enrichment analysis results, developmental heatmap, and a gene sub-network extracted for the module, etc.
Here are some example of the modules (click the links to reach their web-pages).
For examples, Module #16,
Module #XX, for …
Module #XX, for …
Or the Module # 1 – 100,
To reach other modules, use the buttons and links below:
101 – 200, 201 – 300, 301 – 400, 401 – 500, 501 – 600, 601 – 700, 701 – 800, 801 – 900, 901 – 964
