Auxin is a plant hormone that significantly plays important role in plant growth cell division and differentiation, in fruit development, in the formation of roots from cuttings, and in leaf fall. Auxin has many important functions for plant growth. The main function of auxin is to help the plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant is one of the main places that auxin is produced. It promotes stem elongation, inhibits the growth of lateral buds maintains apical dominance. Auxin is produced in different parts of plants such as the stem, buds, and root tips in the form of chemical compounds such as indole acetic acid that significantly increase the growth of plants. Auxin is a plant hormone produced in the stem tip that promotes cell elongation. Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. Auxin biosynthesis plays essential roles in many developmental processes including gametogenesis, embryogenesis, seedling growth, vascular patterning, and flower development. The aims of this review are the potential roles of auxins in plants such as roles in root development, functions in the growth of leaves structures and lastly, the formation of flowers by increasing auxins have been studied in this review. The functions of auxins in plants have not been completely studied.
