Abstract Tomato(Solanum lycopersicum L.)resistance to drought is controlled by many microeffect locus and hundreds genes affecting drought morphology and physiological response.It is helpful to expound tomato drought resistance molecule mechanism and develop molecule marker assisted selection for accelerating the process of breeding new tomato varieties with drought resistance.This paper reviewed the research progress made in studying tomato drought resistance molecule mechanism,changes in tomato morphological characteristics under drought condition,and drought resistance breeding.The paper laid emphasis on illustrating the research progress in tomato drought resistant gene engineering,so as to further applying modern biological technology to provide method and thoughts for plant drought resistance gene engineering improvement and molecule marker assisted selection and breeding.
