Question

Quizplus · Accepted Answer

Protein serine/threonine kinases are the most predominantly used signaling mechanism in plants. This is because they are involved in a wide range of cellular processes including stress responses, hormone signaling, and development. While other signaling mechanisms may also be present in plants, the importance of protein serine/threonine kinases in regulating plant growth and development is well established.
