Medicago Omics Repository

Medicago-Omics Repository

Legumes have the unique ability to form a symbiotic association with soil bacteria, named rhizobia, and host them intracellularly in specialized organs called root nodules. Inside of nodule cells, the rhizobia can fix atmospheric nitrogen and transfer it to the plants in exchange of a carbon source. This interaction is generally characterized by a high level of host specificity and commences with an exchange of diffusible signals between legumes and rhizobia. Flavonoids and isoflavonoids present in the legume root exudates induce the expression of nod genes in rhizobia, and are responsible for the production and secretion of bacterial lipochitooligosaccharides (LCOs), known as Nod factors (NFs). Here we present quantitative transcriptomic, proteomic, and phosphoproteomic analysis of NF induced regulation within Medicago.


To search this database:

Enter a Medicago gene ID number (e.g, Medtr4g030140) or protein description (e.g., Dynamin-2B) in the appropriate line and check the appropriate box (gene ID or protein description). After clicking search a list of protein entries will be displayed. Clicking the (+) button displays overall quantitative information for RNA, protein, and phosphorylation sites for the given gene ID entry. Results from individual experiments can be displayed by clicking (+) next to the protein or phosphorylation site entry.
