symbiosis receptor-like kinase (SYMRK) is another type of receptor involves several function. Which of the following is incorrect?

#Unit 6. System Physiology – Plant

This receptor also contains two types of domain−LysM domain and Kinase domain
SYMRK is thought to activate subsequent steps including fluctuations in the calcium concentration, called calcium spiking
These fluctuations, inside and around the nucleus of the infected epidermal cell, which causes the activation of the core symbiotic genes
The final steps leading to nodulation involve cytokinin signaling
