Research Progress of Sucrose Invertase in Higher Plants

Sucrose is the main product of photosynthesis of higher plants,one of the main modes of transport in plants are sugar,which plays an important role in the process of plant growth and development. Sucrose Invertase( Sucrose invertase,INV) could not reversible catalytic sucrose hydrolysis to glucose and fructose,which plays an important role for the use of sucrose and transportation. Many studies suggest that there are many kinds of sucrose invertase isoenzyme in the plant tissue. Invertase genes are evolving in the process of environmental stress and evolution,eventually forming the sucrose invertase gene families what we see now. Regulation of sucrose invertase mainly includes two aspects: the mRNA level of regulation and inhibiting protein regulation after translation. In the translated regulation of inhibitor protein,there is a certain type of small 20 kD sucrose invertase inhibiting protein( Sucrose invertase inhibitor,INVINH) can inhibit the activity of sucrose invertase,rising to adjust the action of plant physiological activities.
