Takeaways:
- Researchers have found that plants use a system called hydrosignalling to manage where roots branch in response to water availability in the soil.
- They also found that leaves can stop water loss during drought by closing micro-pores on their surfaces.
- Roots from tomato, thale cress, maize, wheat and barley all respond to moisture in this way.
