Medicago truncatula is a model system for studying crop species in the family Fabaceae. The Plant Genome Research Program of the National Science Foundation funded the first of a growing number of genomics projects involving this species in 1998. The goals of the initial project included EST sequencing and microarray development, comparative genetics and genomics between Medicago truncatula, the crop legumes pea, alfalfa, and soybean, and bioinformatics. The project was recently renewed through 2006 with a focus on transcriptional profiling, physical map development, and bioinformatics. The Center for Medicago Genomics Research was established at The Samuel Roberts Noble Foundation in 1999. The objectives of the center pertinent to genomic biology are to provide the organization for large-scale EST sequencing and to facilitate the construction of an information engine that can bring the genomic data to bear upon other biological questions concerning Medicago truncatula.
The sequencing project of the approximately 500-Mbp genome is a US/EU collaboration. The Mt2.0 is available. Annotation is being performed by the International Medicago Genome Annotation Group, IMGAG: TIGR, INRA Toulouse, MIPS, University of Minnesota, Ghent University, University of Oklahoma, and NCGR.
Four genetic maps are available in Map Viewer. Detailed information for the maps is available in the BioProject database.
