Newly identified gene offers options for breeding nematode resistant crops
Although a few receptors, so-called resistance genes, providing protection against specific types of plant-parasitic nematodes have already been identified, NILR1 recognizes rather a broader spectrum of nematodes. "The nice thing about NILR1 is that it seems to be conserved among various crop plants and that it provides protection against many nematode species," says group leader Dr. Shahid Siddique. "The discovery of NILR1 also raises questions about the nematode derived molecule, whose recognition is thought to be integral to this process." Now that an important receptor is discovered, the scientists are working to find the molecule which binds to NILR1 to switch on the immune responses. The two first authors, PhD students at the department share tasks in the project. Whereas Mary Wang Ombe focuses on the receptor protein and its function, Badou Mendy concentrates on isolating the signal molecule released by the nematodes.
