According to researchers at the University of Queensland, when plants are stressed, they send defensive signals like humans do. The researchers found that plants have genetic machinery used by people to smell and see their environment, and to repel threats.
Professor Jimmy Botella, a plant biotechnologist, reported that the University of North Carolina carried a research on a family of proteins known as G-proteins in the Brassica family. According to the professor, plants have adopted the machinery used by human beings to see in order to protect themselves against water stress and pathogens.
In humans, G-proteins assist people to sense Adour, flavour, light, and are involved in mood regulation and behavior through things such as serotonin, dopamine, histamine, and adrenalin. Almost all living organisms have G-proteins. Nearly half of all human medications attain their effects via G-protein–coupled receptors.
“The main difference between most animals and animals – that while animals avoid stress situations by moving, plants are stuck in one location and need to develop ingenious solutions to survive,” Professor Botella said.
G-proteins have been broadly studied in animal systems. However, this genetic machinery in plant systems is still mostly unknown.
