E) protein tyrosine kinases

Question

Quizplus · Accepted Answer

The most predominant signaling mechanism in plants is the phosphorylation of proteins by protein serine/threonine kinases. These kinases play a key role in regulating a variety of cellular processes, including growth, development, and stress responses. While other signaling mechanisms, such as G protein-coupled receptors and protein tyrosine kinases, are also present in plants, they are not as important as protein serine/threonine kinases.
