Roots, the hidden half in stressed environment

Abstract

The root as it grows below ground supports and anchors the plant body. It likewise performs significant roles in water uptake, efficient acquisition of minerals from the growth medium, modification of the rhizosphere, and in association with the soil microflora. The simple structure of the root makes it suitable not only for studying growth and morphogenesis but also serves as a model system for biochemical studies and in biotechnology. Under adverse conditions of the environment, roots are able to carry out morphogenetic and physiological adaptation. This paper presents our studies and some of others on how the root acclimates when exposed to various abiotic stresses experienced both by itself and the shoot.
