Roots of plants too, respond to the changes in climate.
It has been found in a study that plant roots extend their branches or stop extension according to availability of moisture.
In this research scientists have discovered that specific hormones in plant roots cast impact on the ramification of roots as per the availability of water.
The effect of climate change on soil side by side the growth and development of plants has been studied, but very few studies have been done on roots. In this study it has been found that roots change their ramification according to drought conditions. Thus, they protect the life of plant in droughts.
When plant roots loose contact with water, they stop their development.
Scientists of Nottingham University have found that there is a system of Hydro signaling in plant roots.
Results of this study show how the activities of hormone is related to the availability of water. The climate change has increased the pressure of water on water.
This is because an irregularity in the forms of rains has been reported and more impact has been seen on the crops depending more on rain.
Roots develop adaptations to reduce the pressure of water on plants so that they can absorb more water.
By x-ray imaging, researchers have found that roots change their shapes by developing a connection with hormones.
These researches have reported about certain genes that help coordinate availability of water with the crop production.
Dr. Poonam Mehra has reported that when roots come in contact of moisture, a specific hormone called auxin becomes active and it accelerates the formation of new roots. But when roots loose contact with water, the hormone stops their further growth.
