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 ...
In a stem, the cells on the shaded side contain more auxin and grow longer than the cells on the light side. This causes the stem to grow towards the light. It is vital to note that the plant does ...
However, certain bacteria can hack this system. Another key player in this evolutionary back-and-forth are plant hormones called auxins. Auxins are an important class of hormones that affect how ...
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 ...
