Abstract: Circuitous roots Normally, legumes develop nitrogen-fixing root nodules only when invaded by rhizobia bacteria. In an unusual Lotus japonicus mutant, nodulation occurs spontaneously in the absence of bacteria, due to the activity of a modified signalling pathway kinase. This has major implications for plant biotechnologists, since the transfer of root nodule formation to non-leguminous crops might be an elegant way of making them independent of nitrogen fertilizers.
