Protein signaling between soybean root hairs, bacteria reveals core cellular processes

(Phys.org)—Understanding what happens to a soybean root hair system infected by symbiotic, nitrogen-fixing soil bacteria, Bradyrhizobium japonicum, could go a long way toward using this symbiosis to redesign plants and improve crop yields, benefitting both food and biofuel production. Because of their extensive genomes, it is especially difficult to use conventional proteomic technologies to get meaningful information from plants. With the availability of a complete soybean genome, soybean root hairs represent an excellent model for the study of single-cell systems biology.
