Abstract:

Water is a key factor influencing the growth and development of rice. Exploring mechanisms for efficient water utilization is vital for rice production. During the process of plant growth and development, the root system secretes various compounds into the surrounding environment, known as root exudates. These substances regulate plant growth and development by triggering rhizosphere effects and constitute an indispensable part of plant growth process. This paper systematically reviews the types, biosynthetic pathways of root exudates, and their physiological response mechanisms under drought stress. By providing an in-depth analysis of the function mechanisms of rice root exudates in water regulation, this review identifies existing problems in current research and proposes suggestions for future research directions.

Key words: Rice, Drought stress, Root exudates, Rhizosphere environment
