Symbiotic nitrogen-fixing rhizobia release nodulation (Nod) factors as signaling agents as they near the surface of a legume root. The interaction between specific nod factors and their corresponding receptors. Which of the following statements is incorrect?

#Question id: 10377

#Unit 6. System Physiology – Plant

Nod factors are recognized by the Nod factor receptor (NFR) in legumes, Upon binding to Nod factors, the NFR heterodimer initiates two main separate processes mediated by SYMRK such as;

a) A signaling pathway that facilitates the infection process itself

b) Activation of the symbiosis receptor-like kinase (SYMRK)

c) Activating an extracellular domain that includes a leucine rich repeat (LRR) region and an intracellular protein kinase domain

d) The activation of a set of genes that regulate the formation of root nodules

Which of the following are the two main separate processes of NFR heterodimer?

#Unit 6. System Physiology – Plant

Two separate processes, the first involves a signaling pathway that facilitates the infection process itself and  the second involves the activation of a set of genes that regulate the formation of root nodules. Which of the following receptor is thought to participate in both processes?
