Auxin
Auxin is a vital plant hormone which regulates growth and development processes in plants. It plays an important role in cell elongation, root initiation, and apical dominance. Auxin promotes phototropism by stimulating cell elongation on the shaded side of plant stems, leading to bending towards light. It also influences gravitropism, directing root growth downward and stem growth upward. Additionally, auxin is involved in tropic responses like geotropism and thigmotropism. Its distribution within plant tissues is tightly regulated through polar transport which ensures control over plant growth and responses to environmental stimuli.
Auxin
Auxin is a plant hormone. Auxin hormone function is to control growth and developmental processes in plants, including cell expansion, root initiation, and bud and flower growth. Auxin, discovered by Charles Darwin and his son Francis, was first isolated from human urine.
Auxin plays a key role in plant adaptation to the environment, and its functions are associated with signal transduction, transport, homeostasis, and biosynthesis pathways. In this article, we will study the auxin, its types, mechanism of action, and functions in detail.
