PLANT SCIENCE: GRAS Genes and the Symbiotic Green Revolution
Michael K. Udvardi and Wolf-Rüdiger Scheible
The symbiotic relationship between legumes and their resident nitrogen-fixing bacteria (rhizobia) begins when the plant senses the bacteria and develops a specialized nodule to house them. The signaling system that triggers nodule development is now known to activate two newly described transcription factors (Kaló et al. and Smit et al.). In their Perspective, Udvardi and Scheible explain that this new information completes a missing link and that we can now trace the molecular events from initial rhizobium detection to nodulation gene activation.
