TXK and viral infectious disease: This coevolutionary triad is supported by various aspects: (i) meristematic tissues exhibit high LRRII-RLK activity and low viral infection activity, (ii) viruses have strategies that manipulate proteins, which participate in plant growth/development, just as several LRRII-RLK coreceptors, (iii) plants dynamically adjust coreceptor activity to balance growth and immunity, defining a highly specialized interaction landscape.
