The β-1,3-glucanase that we have known are all members of the17th family. In the plants, β-1,3-glucanase is one of the most important resistance material which can resist fungal disease. Most studies in vitro showed that β-1,3-glucanase can hydrolyze the cell wall of fungus and inhibit its growth. In addition, β-1,3-glucanase plays an important role in hydrolyzing β-glucan in cereals. Nowadays, β-1,3-glucan-ase is widely used in beer, feed industries. In the study, we want to complete the cloning and expres...
