Unbelievable research has been made in understanding Auxin biosynthesis and its effect on physiological process and developments in plants over the last few years. Auxin is a phytohormones that’s involved in many physiological and biological functions of the plants i.e. basic cellular processes and cell cycle control over localized responses such as cell elongation and differential growth. Both plants and some plant pathogens produce Auxin for completing normal life cycle. But, however, how Auxin produces in plant this process is difﬁcult to be proven. Number of research studies had discovered biochemical reactions and several genes in tryptophan-dependent Auxin biosynthesis pathway. Even though the history of auxin research reaches back more than a hundred years, we are still far from a comprehensive understanding of how auxin controls plant growth and physiological process. Some answers to this question may lie in the auxin molecule itself. Naturally occurring auxin-like substances have been found and they may play roles in specific developmental and cellular functions. The molecular mode of auxin action can be further explored by the utilization of synthetic auxin-like molecules i.e NAA (naphthalene acetic acid) and IBA (indole-butynic acid). Auxin is actively modified, metabolized, and intra-cellular compartmentalized, that’s have a great impact on its availability and activity. In this review, we will give an overview of these recent and emerging areas of auxin and its effect on plant physiological process and developments and try to formulate some of the open questions. Without doubt,
the manifold facets of auxin biology will not cease to amaze us for a long time to come.
