Abstract:

As one of the serious environmental factors, soil salinization has severely restricted plant growth and development worldwide. Root system plays significant role in the regulation of plant responded to stress. However, most previous studies about plant stress tolerance focused on the aboveground. As the first organ to perceive and response to the environmental stress, stress tolerance of root system was still unclear. For this reason, the mechanism of plant roots responded to soil saline-alkali stress was summarized from the perspectives of root system architecture, structure, growth, physiology and molecular biology, and shortcomings and prospects were also put forward in this manuscript. The aim was to provide a scientific basis for further revealing the function of plant root system and its saline-alkali stress tolerance mechanism.

Key words: root, salt stress, alkaline stress, root architecture, physiological mechanism
