![HvRLK4 and HvRLK10 can activate the symbiotic pathway in Medicago. (A) Representative bright-field and YFP fluorescence (transformation control) images of Medicago roots expressing RLK4-2xLaG16 and RLK10-GFP depicted to the right. Scale bar = 1 mm. (B) Number of nodules formed on plants expressing the indicated constructs in the absence of rhizobia. Nodules were counted nine weeks after hairy root transformation. Circles represent individual plants. Numbers below the boxplots specify number of nodulated plants out of total number of plants. Lowercase letters indicate significant differences between samples [analysis of variance (Kruskal-Wallis) and post-hoc analysis (Dunn’s test), p < 0.05].

Novel strategy for engineering root nodule symbiosis into important crops for more sustainable agri-food systems
Legume plants do not depend on externally supplied nitrogen, because they can form a symbiosis with nitrogen-fixing bacteria, called rhizobia. The ...
