Abstract
One of the major challenges in Brazilian sugarcane production is the weevil Sphenophorus levis. The major digestive proteins of S. levis belong to cysteine peptidases (cathepsins L -like). Sugarcane, on the other hand, presents endogenous defense by the production of phytocystatins, cysteine peptidases inhibitors. Based on sugarcane EST library (SUCEST), Laboratory of Molecular Biology …
