Hormonal Regulation of Root Development Under Water Stress

Part of the Advances in Agricultural Biotechnology book series (AABI, volume 21)


Root growth studies have been receiving greater attention in recent years than before. In the early years, detailed studies on the physiology of above-the-ground parts were carried out, whereas the investigations on root development received scant attention. However, with the advent of growth chamber facilities with controlled environmental conditions and clear understanding of the multifarious roles of the root in plant’s life, extensive investigations have been launched during the last two decades in different laboratories around the world. Besides its essential role in the absorption of water and nutrients, the root also performs the main function of synthesising growth hormones and of facilitating their translocation, like water and mineral nutrients, to the shoot. Thus, shoot development is greatly influenced by the supply from roots.
