Medicago Gene Expression Atlas
Medicago truncatula is a model or reference species for legume genetics, genomics, and breeding. Transcriptomics using DNA microarrays enable researchers to measure gene expression throughout the plant on a genome-wide scale. Bioinformatic analysis of microarray data yields insight into the potential role of genes and gene products in plant growth, development, and response to the environment. With funding from the NIFA National Research Initiative Plant Genome Program, researchers at the Samuel Roberts Noble Foundation and partner institutions describe a novel repository of such data for the legume family: The Medicago Gene Expression Atlas. Data were generated for three biological replicates of all the major organ systems of this model legume using the Affymetrix Medicago GeneChip, which contains over 50,000 probe-sets for Medicago genes. The data described here and contained in the corresponding database is the most comprehensive set of transcriptome data available for any legume, and the database will be up-dated regularly with complementary data as it becomes available.
Bioinformatic analysis of microarray data yields insight into the potential role of genes and gene products in plant growth, development, and response to the environment. This data will increase knowledge about legumes, which account for one-third of the world’s primary crop production.
Their research was featured on the cover of Volume 55, Issue 3 of The Plant Journal published in August 2008.
