The identification of novel loci required for appropriate nodule development in Medicago truncatula.

ABSTRACT:

Background

The formation of functional symbiotic nodules is the result of a coordinated developmental program between legumes and rhizobial bacteria. Genetic analyses in legumes have been used to dissect the signaling processes required for establishing the legume-rhizobial endosymbiotic association. Compared to the early events of the symbiotic interaction, less attention has been paid to plant loci required for rhizobial colonization and the functioning of the nodule. Here we describe the identification and characterization of a number of new genetic loci in Medicago truncatula that are required for the development of effective nitrogen fixing nodules.

Results

Approximately 38,000 EMS and fast neutron mutagenized Medicago truncatula seedlings were screened for defects in s
