Belowground plant-plant interaction by common mycorrhizal network (CMN)

We all know that Plants are sessile organisms they cannot go and talk like us, but plants continuously interact with each other and share their environment by different ways of communication. One of the important ways of interplant communication is belowground communication through Common Mycorrhizal Network, Plants are so kind they care and share each other, they use Common Mycorrhizal Network for sharing the nutrients and defence signals.
