Summary Introduction
To review:
The oldest signaling pathway based on the distribution among different group of organisms.
Introduction:
Cell communication is the process of sending cell signals from one cell to another cell, which triggers response for activation of many proteins molecules. It takes place in unicellular as well as in multicellular organisms including plants,
