Sucrose is the main output form of plant photosynthate.During the growth of the plants,sucrose could be decomposed by both sucrose synthase and invertase,and the latter catalyzes the irreversible hydrolysis of su-crose into glucose and fructose,which provides carbon framework and energy for plants and affects their growth,development and morphogenesis.In addition to affecting the primary metabolism of plants,invertase genes are specifically expressed under stress conditions,and invertase plays an important role in cellulose biosynthesis.In this paper,the classification,biochemical characteristics,physiological functions and expression regulation of in-vertases in plants were summarized,with emphasis on the corresponding functions of invertase during the stress re-sponse in plant,which has certain reference value for further research on the physiological function of invertase in the process of the cellulose synthesis.
