Auxins are involved in a variety of plant growth responses. The elongation of stems is promoted by
auxins, as is the growth of stems so that they bend toward light. Auxins also promote fruit
development and inhibit leaf abscission. Auxins also promote dormancy in lateral buds. In the roots,
auxin promotes lateral growth. Auxin also is involved in orientation of growth with respect to gravity
in both shoots and roots.
