11. During his career Bisseling has done research on the symbiosis between root nodules and rhizobia bacteria. 12. Like other legumes, they can rhizobium root nodule symbiosis, fertilizing the soil for other plants. 13. Larvae are found on fresh and decaying vegetation, carrion, human corpses, and root nodules . 14. It forms nitrogen-fixing root nodules on legumes in the genus " Galega ". 15. The American genus " Ceanothus ", which has several showy nitrogen-fixing root nodules . 16. The plant hormones called cytokinins initiate root nodule formation, in a process closely related to mycorrhizal association. 17. The root nodule formation by " Sinorhizobium meliloti " is apparently dependent on the flavonoids pathway. 18. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules . 19. In addition, soybean uses isoflavones to stimulate soil-microbe rhizobium to form nitrogen-fixing root nodules . 20. In this interaction, rhizobia bacteria induce root nodule formation in legume plants via an exchange of molecular signals.
