Abstract excerpt

To address a critical gap in understanding amino acid transport in legume-Rhizobium symbiosis, we investigated the role of symbiosis-associated USUALLY MULTIPLE ACIDS MOVE IN AND OUT TRANSPORTERS (UMAMITs) in Medicago truncatula nodulation. Transcript profiling, phylogenetic analysis and promoter-reporter fusions identified five symbiosis-associated MtUMAMIT genes. CRISPR-Cas9 genome editing generated two triple...
