When the stem grows against the force of gravity (upwards), this is known as a negative gravitropism. When a root grows in the direction of the force of gravity (downwards), this is known as a ...
which enhances root gravitropism to grow them at steeper angles in response to drought. Experiments showed that plants with genetic mutations that block ABA production had shallower root angles ...
