We propose a role for the plant hormone auxin as an integrator of the activities of multiple plant hormones to control plant growth in response to the environment. Plants are sessile organisms and ...

The researchers found a novel mechanism in which auxin production is stimulated by ABA, leading to increased root gravitropism and the ability to grow at steeper angles in response to drought.

Just like phototropism, gravitropism is also caused by an unequal distribution of auxin. When a stem is placed horizontally, the bottom side contains more auxin and grows more - causing the stem ...

Scientists have discovered how plants adapt their root systems in drought conditions to grow steeper into the soil to access deeper water reserves. Plant scientists from the University of ...
