Fig. 1From: Rapid identification of causative insertions underlying Medicago truncatula Tnt1 mutants defective in symbiotic nitrogen fixation from a forward genetic screen by whole genome sequencingOverview of forward genetic screening for symbiotic mutants and identification of causative genes. Steps in forward genetic screening and identification of causative genes responsible for M. truncatula Tnt1 mutants defective in nodule development and symbiotic nitrogen fixation are shownBack to article page
