Effect of Chitinolytic enzymes on the structure germ tubes of H. vastatrix after 18 h of treatment application. MBP (Maltose binding protein). Germinating uredospores treated with a. water, showing normal growth; b. BSA (Bovine Serum Albumin) displaying increased cell wall thickness; c. MBP/endochitinase and d. MBP/exochitinase, resulting in germ tubes either broken or shrunken. (Bar = 20 μm).
