Mind Map for Auxin
Auxins are a group of naturally occurring and artificially synthesised plant hormones. They play an important role in the regulation of plant growth. Auxins were initially isolated from human urine.
Auxin means to “enlarge” or “increase”. They induce cell division, differentiation and elongation.
Charles Darwin detected phototropism movement (bending of plants towards light) in the coleoptile of canary grass. He observed that there was some influencer at the tip of the coleoptile, which was responsible for the bending towards the light.
Later, Frits Went isolated and named the substance as “Auxin”, which was responsible for phototropic movement in oat coleoptile.
Kenneth Thimann purified and elucidated the structure of primary auxins, e.g. IAA (Indoleacetic acid).
Naturally Occurring Auxins: Indole-3-acetic acid (IAA), Indole butyric acid (IBA)
Artificially synthesized Auxins: 2,4-dichloro phenoxy acetic acid (2,4-D), Naphthalene acetic acid (NAA)
