The Medicago Genome Initiative: a model legume database

Area of Science:

• Plant Genomics
• Functional Genomics
• Legume Biology

Background:

• The Medicago Genome Initiative (MGI) database houses expressed sequence tag (EST) data for the model legume Medicago truncatula.
• MGI is a collaborative effort between the Samuel Roberts Noble Foundation and the National Center for Genome Resources.
• It is part of a larger integrated functional genomics program focused on Medicago truncatula.

Purpose of the Study:

• To create a publicly accessible database of Medicago truncatula EST sequences.
• To support a global approach to studying the genetic and biochemical events in legume growth, development, and environmental interactions.
• To provide an integrated set of tools for legume biology research.

Main Methods:

• Large-scale EST sequencing.
• Gene expression profiling.
• Generation of insertion mutants (activation-tagged and promoter trap).
• High-throughput metabolic profiling and proteome studies.

Main Results:

• Establishment of the MGI database with EST sequences.
• Integration of multidisciplinary data pools (genomics, transcriptomics, proteomics, metabolomics).
• Development of a public interface for database access.

Conclusions:

• The MGI database offers a holistic resource for scientists studying legume biology.
• The integrated approach facilitates fundamental research questions in plant genomics and functional genomics.
• Public accessibility promotes collaborative research and advances understanding of Medicago truncatula.
